如图1至图7所示，移相器传动装置100包括壳体101、主轴103、换档结构105、第一动力机构(即辅助动力机构)107、第二动力机构(即主动力机构)109、斜齿轮1130a-1130j、齿轮113a-113j以及输出单元111a、111b、111c、111d、111e、111f、111g、111h、111i、111j，齿轮113a-113j分别通过传动轴(图中未标注出)与斜齿轮1130a-1130j相连接，每个输出单元设有与齿轮113a-113j中的相应的蜗杆啮合的齿条，使得齿轮113a-113j转动时能够带动相应的输出单元移动，从而驱动相应的移相器产生运动。其中，壳体101包括子壳体101a和与子壳体101a适配的子壳体101b，主轴103设置在子壳体101b中(应理解的是，主轴103也可以设置在子壳体101a上)。As shown in Figures 1 to 7, the phaseshifter transmission device 100 includes ahousing 101, amain shaft 103, ashifting structure 105, a first power mechanism (i.e. an auxiliary power mechanism) 107, a second power mechanism (i.e. a main power mechanism) 109.Helical gears 1130a-1130j,gears 113a-113j andoutput units 111a, 111b, 111c, 111d, 111e, 111f, 111g, 111h, 111i, 111j, andgears 113a-113j respectively pass through transmission shafts (not marked in the figure) Connected with thehelical gears 1130a-1130j, each output unit is provided with a rack meshed with the corresponding worm in thegears 113a-113j, so that thegears 113a-113j can drive the corresponding output unit to move when rotating, thereby driving the corresponding moving gear The phaser produces motion. Wherein, thehousing 101 includes asub-housing 101a and asub-housing 101b adapted to thesub-housing 101a, themain shaft 103 is arranged in thesub-housing 101b (it should be understood that themain shaft 103 can also be arranged on thesub-housing 101a ).

如图2、图3a和图7所示，主轴103上设有可沿主轴103的轴线方向移动的蜗杆104a、104b。在此，设置两个蜗杆104a和104b仅仅是示例性的而非限制性的，可以根据需要设置一个或者多个蜗杆。主轴103上还设有蜗轮103g，本领域的技术人员应当了解，此处的主轴103和涡轮103g通常固定连接，即不会发生相对转动。换档结构105可移动地(例如，沿着垂直于主轴103的轴线方向的方向上)设置在壳体101内。应理解的是，尽管图中所示的实施例中，主轴103上设有两个蜗杆，但是在另外的实施例中，主轴103上仅设有一个蜗杆或者三个以上的蜗杆。As shown in FIG. 2 , FIG. 3 a and FIG. 7 , themain shaft 103 is provided withworms 104 a , 104 b that can move along the axial direction of themain shaft 103 . Here, setting twoworms 104a and 104b is only exemplary and not limiting, and one or more worms can be set as required. Themain shaft 103 is also provided with aworm gear 103g. Those skilled in the art should understand that themain shaft 103 and theworm wheel 103g are usually fixedly connected, that is, there is no relative rotation. The shiftingstructure 105 is movably (eg, along a direction perpendicular to the axial direction of the main shaft 103 ) disposed inside thehousing 101 . It should be understood that, although in the embodiment shown in the figure, themain shaft 103 is provided with two worms, in other embodiments, themain shaft 103 is provided with only one worm or more than three worms.

继续如图3a和图7所示，换档结构105上设有沿平行于主轴103的轴线方向的方向布置的齿条105a。当换档结构105处于第一位置时，蜗杆104a和蜗杆104b与齿条105a啮合，此时通过第二动力机构109的驱动将使得蜗杆104a借助于齿条105a改变蜗杆104a和104b在主轴103上的位置，从而实现对于不同的输出单元111a、111b、111c、111d、111e、111f、111g、111h、111i、111j的选择，进而实现对于不同的移相器的选择。此时，涡轮104a和涡轮104b并不与其上方的斜齿轮1130a-1130j啮合。相应地，当换档结构105处于与第一位置不同的第二位置时，蜗杆104a和蜗杆104b不与齿条105a啮合而与其上方的斜齿轮1130a-1130j啮合，此时通过第二动力机构109的驱动将使得蜗杆104a借助于其上方的斜齿轮1130a-1130j啮合传动至相应的输出单元111a、111b、111c、111d、111e、111f、111g、111h、111i、111j，进而实现对于相应的移相器的驱动。As shown in FIGS. 3 a and 7 , the shiftingstructure 105 is provided with arack 105 a arranged in a direction parallel to the axial direction of themain shaft 103 . When the shiftingstructure 105 is in the first position, theworm 104a and theworm 104b are engaged with therack 105a, and the driving of thesecond power mechanism 109 will make theworm 104a change theworm 104a and 104b on themain shaft 103 by means of therack 105a. position, so as to realize the selection ofdifferent output units 111a, 111b, 111c, 111d, 111e, 111f, 111g, 111h, 111i, 111j, and then realize the selection of different phase shifters. At this time, theturbines 104a and 104b are not meshing with thehelical gears 1130a-1130j above them. Correspondingly, when the shiftingstructure 105 is in the second position different from the first position, theworm 104a and theworm 104b do not mesh with therack 105a but mesh with thehelical gears 1130a-1130j above it, and at this time thesecond power mechanism 109 The driving of theworm 104a will make theworm 104a be meshed and transmitted to thecorresponding output units 111a, 111b, 111c, 111d, 111e, 111f, 111g, 111h, 111i, 111j by means of thehelical gears 1130a-1130j above it, and then realize the corresponding phase shift device driver.

此外，换档结构105上还设有沿垂直于主轴103的轴线方向布置的切换齿条105b，换档结构105上的切换齿条105b具有限位A和限位B(如图7所示)。以此，换档结构105能够借助于具有限位A和限位B的切换齿条105b实现在上述的第一位置和第二位置之间的切换。In addition, the shiftingstructure 105 is also provided with ashifting rack 105b arranged along the axis direction perpendicular to themain shaft 103, and theshifting rack 105b on the shiftingstructure 105 has a limit A and a limit B (as shown in FIG. 7 ). . In this way, the shiftingstructure 105 can realize switching between the above-mentioned first position and the second position by means of theswitching rack 105b having a limit A and a limit B.

再者，如图3a至图7所示，第一动力机构107设置在子壳体101b上，第一动力机构107包括电机107a、传动轴107b和通过传动轴107b与电机107a相连接的蜗杆107c，蜗杆107c与切换齿条105b啮合，第二动力机构109也设置在子壳体101b上并且与主轴103耦接，具体地，第二动力机构109包括电机109a、传动轴109b、主动齿轮109c、从动齿轮109d、传动轴109e、蜗杆109f。Furthermore, as shown in Figures 3a to 7, thefirst power mechanism 107 is arranged on the sub-housing 101b, and thefirst power mechanism 107 includes amotor 107a, atransmission shaft 107b and aworm 107c connected to themotor 107a through thetransmission shaft 107b , theworm 107c meshes with theswitching rack 105b, and thesecond power mechanism 109 is also arranged on the sub-housing 101b and is coupled with themain shaft 103. Specifically, thesecond power mechanism 109 includes amotor 109a, atransmission shaft 109b, adriving gear 109c, Drivengear 109d,transmission shaft 109e,worm 109f.

移相器传动装置100工作时，电机107a通过传动轴107b驱动蜗杆107c转动从而使得蜗杆107c在切换齿条105b的限位A与限位B之间移动。当蜗杆107c位于限位B时，换档结构105使得蜗杆104a和104b处于换档选位模式的工作状态，此时，蜗杆104a、104b与齿条105a啮合，电机109a通过传动轴109b驱动主动齿轮109c转动，从动齿轮109d跟随主动齿轮109c转动。进一步地，从动齿轮109d通过传动轴109e带动蜗杆109f转动，从而带动蜗轮103g转动，进而带动主轴103转动，蜗杆104a、104b可以随着主轴103的转动移动到目标档位(即目标输出单元所在的档位)。When thephase shifter transmission 100 is working, themotor 107a drives theworm 107c to rotate through thetransmission shaft 107b so that theworm 107c moves between the limit A and the limit B of theswitching rack 105b. When theworm 107c is at the limit B, the shiftingstructure 105 makes theworms 104a and 104b in the working state of the gear selection mode. At this time, theworms 104a, 104b mesh with therack 105a, and themotor 109a drives the driving gear through thetransmission shaft 109b 109c rotates, and the drivengear 109d follows the rotation of thedriving gear 109c. Further, the drivengear 109d drives theworm 109f to rotate through thetransmission shaft 109e, thereby driving theworm wheel 103g to rotate, and then driving themain shaft 103 to rotate, and theworms 104a, 104b can move to the target gear with the rotation of the main shaft 103 (that is, where the target output unit is located) stalls).

当蜗杆107c位于限位A时，换档结构105使得蜗杆104a和104b处于驱动模式，此时，蜗杆104a、104b分别与齿条105a分离，并且分别与例如斜齿轮1130a、1130f啮合，蜗杆104a、104b随着主轴103的转动而移动(应理解的是，移动方向取决于主轴旋转方向及蜗杆旋向)，进而带动斜齿轮1130a、1130f转动。相应地，带动齿轮113a、113f转动，进一步地，齿轮113a、113f通过与其啮合的齿条带动相应的输出单元111a、111f移动，从而驱动与输出单元111a、111f相连接的移相器产生运动。此外，换档结构105还设置有与档位数量相一致数量的限位部(例如限位槽105c)，限制蜗杆104a、104b沿轴线方向的自由度，即防止蜗杆104a、104b随着主轴103的转动而转动的同时沿着主轴103的轴线方向移动。When theworm 107c is at limit A, the shiftingstructure 105 makes theworms 104a and 104b in the driving mode. At this time, theworms 104a, 104b are respectively separated from therack 105a, and are respectively meshed with, for example,helical gears 1130a, 1130f. 104b moves with the rotation of the main shaft 103 (it should be understood that the moving direction depends on the rotation direction of the main shaft and the worm screw), and then drives thehelical gears 1130a, 1130f to rotate. Correspondingly, thegears 113a, 113f are driven to rotate, and further, thegears 113a, 113f drive the correspondingoutput units 111a, 111f to move through the gear racks meshed with them, thereby driving the phase shifters connected to theoutput units 111a, 111f to generate motion. In addition, the shiftingstructure 105 is also provided with a number of limit portions (such aslimit grooves 105c) corresponding to the number of gears to limit the freedom of theworms 104a, 104b along the axial direction, that is, to prevent theworms 104a, 104b from moving with themain shaft 103. It moves along the axial direction of themain shaft 103 while rotating.

在另一个实施例中，第一动力机构107与换档结构105上配置有电磁继电器，其中，电磁继电器的电磁铁设置在第一动力机机构上，电磁继电器的衔铁设置在换档结构上，可以通过电磁继电器实现第一蜗杆在驱动模式与换档选位模式之间的切换。In another embodiment, an electromagnetic relay is arranged on thefirst power mechanism 107 and the shiftingstructure 105, wherein the electromagnet of the electromagnetic relay is arranged on the first power mechanism, and the armature of the electromagnetic relay is arranged on the shifting structure, which can The switching of the first worm between the driving mode and the gear selection mode is realized through the electromagnetic relay.

应理解的是，尽管上述实施例中，输出单元111a、111b、111c、111d、111e、111f、111g、111h、111i、111j的数量为10个，但是在另外的实施例中，输出单元111a、111b、111c、111d、111e、111f、111g、111h、111i、111j可以有任意多个。此外，应理解的是，在另一个实施例中，第一动力结构107和第二动力机构109可以不局限于设置在移相器传动装置的中间位置，第一动力结构107和第二动力机构109可以设置在任意合适的位置。It should be understood that although in the above embodiment, the number ofoutput units 111a, 111b, 111c, 111d, 111e, 111f, 111g, 111h, 111i, 111j is 10, in another embodiment, theoutput units 111a, There can be any number of 111b, 111c, 111d, 111e, 111f, 111g, 111h, 111i, 111j. In addition, it should be understood that, in another embodiment, thefirst power structure 107 and thesecond power mechanism 109 may not be limited to be arranged at the middle position of the phase shifter transmission, thefirst power structure 107 and thesecond power mechanism 109 can be set at any suitable position.

在图1至图7所示的实施例中，诸如主电机的第二动力机构109通过直齿轮和蜗轮蜗杆的结合来传递动力。在图8和图9所示的实施例中，与图1至图7所示的实施例的不同之处在于，移相器传动装置200的换档结构与第一动力机构207啮合的齿条设置在平行于主轴的轴线方向的方向上。相应地，第一动力机构207通过传动轴带动的齿轮的方向也做了相应的调整。第二动力机构209略去了直齿条结合蜗轮蜗杆的传动结构，电机转动直接带动斜齿轮转动来驱动输出单元运动。在另一个实施例中，第二动力机构209也可以通过锥齿轮啮合传递动力来驱动输出单元运动。In the embodiment shown in FIGS. 1 to 7 , thesecond power mechanism 109 such as a main motor transmits power through a combination of spur gears and worm gears. In the embodiment shown in FIGS. 8 and 9 , the difference from the embodiment shown in FIGS. 1 to 7 lies in that the shifting structure of thephase shifter transmission 200 is engaged with the rack gear of thefirst power mechanism 207 arranged in a direction parallel to the axial direction of the main shaft. Correspondingly, the direction of the gear driven by the transmission shaft of thefirst power mechanism 207 is also adjusted accordingly. Thesecond power mechanism 209 omits the transmission structure of the spur rack combined with the worm gear, and the rotation of the motor directly drives the rotation of the helical gear to drive the movement of the output unit. In another embodiment, thesecond power mechanism 209 can also transmit power through bevel gear engagement to drive the output unit to move.

It should be understood that, in another embodiment, themain shaft 103 may also be arranged on the sub-housing 101a. In another embodiment, the sub-housing 101a and the sub-housing 101b can be integrally formed.
