Description

Electromagnetism-Gear Planet Transmission buncher

The utility model relates to buncher, particularly a kind of electromagnetism-Gear Planet Transmission buncher by electromagnetic slip clutches and the combination of mechanical type planetary gear speed reducing mechanism.

The infinite variable speed occasion of low speed in industrial transmission, requiring at present, except using mechanical stepless speed change or electric regulation and control speed change, the another kind of technology that generally adopts is respectively to become the product of system to be docking together for these two kinds electromagnetic slip clutches and mechanical reducer, with the infinite variable speed purpose of low speed in reaching.This technology has following weak point:

One, owing to be the product that respectively becomes system, height of center is inconsistent, need do mounting seat in addition during butt joint, and material takies many, and weight increases, the cost height.

The diaxon axiality is strict when two, docking, and the butt joint difficulty of construction is big, and it is many to expend man-hour.

Three, not compact, it is big to take up room.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of compact conformation is provided, and installs and uses simplely, and it is few that space, material take, the middle low speed buncher that cost is low.

Above-mentioned purpose of the present utility model is to realize by such technical scheme, it is electromagnetism-Gear Planet Transmission buncher that the utility model provides, comprise by armature, magnetic pole, magnet exciting coil, the speed measuring device rotor, electromagnetism slip clutch and planetary gear speed reducing mechanism that the speed measuring device stator constitutes, it is characterized in that: described armature, magnetic pole, magnet exciting coil, the speed measuring device rotor, speed measuring device stator and planetary gear speed reducing mechanism all make up on same central axis, described magnetic pole, the speed measuring device rotor is installed on the planetary gear speed reducing mechanism power shaft, and described speed measuring device stator is installed in the magnet exciting coil.

Magnet exciting coil in the above-mentioned technical solution, speed measuring device can external various known exciting current regulation devices.

Speed measuring device in the above-mentioned technical solution can be a tachogenerator, also can be the speed measuring device of pulsed counting speed measuring device and various known other forms.

Epicyclic type of the present utility model mechanism can adopt planetary involute gear reducing gear.

Epicyclic type of the present utility model mechanism also can adopt the few tooth difference speed reducing mechanism of planetary involute gear.

Epicyclic type of the present utility model mechanism also can adopt planetary cycloid tooth reducing gear.

The embodiment progress explanation that said structure of the present utility model can provide by accompanying drawing.

The utility model has following accompanying drawing:

Accompanying drawing 1 is the structural representation of the utility model embodiment 1;

Accompanying drawing 2 is the structural representation of the utility model embodiment 2;

Accompanyingdrawing 3 is the structural representation of theutility model embodiment 3.

Referring to Fig. 1, in this embodiment, adopted planetary involute gear reducing gear.Electromagnetism slip clutch is by armature 1, magnetic pole 2, magnetexciting coil 3, speed measuring device rotor 4, speed measuring device stator 5 constitutes, wherein armature 1 and magnetic sheet 2 no rigid connection in mechanism, borrow air gap to separate, magnetic pole 2, speed measuring device rotor 4 are installed and are connected on the power shaft 6 of planetary involute gear reducing gear A.Armature 1 has the butt hole that docks with motor reel, needs only during butt joint motor reel is inserted the butt hole of armature 1, and utilize the flange of motor end and this electromagnetism-Gear Planet Transmission buncher just can finish butt joint in end flange with bolted.Magnetexciting coil 3 and speed measuring device can external exciting current regulation devices.Do the constant speed rotation by motor drives armature 1 during work, by changing the size of magnet exciting coil electric current, the rotating speed of magnetic pole 2 is changed smoothly and pass to epicyclic type mechanism after just reach by reducer output shaft 7 outputs again in the infinite variable speed purpose of low speed.

Referring to Fig. 2, adopt the few tooth difference speed reducing mechanism B of planetary involute gear among this embodiment, its power shaft 6 is installed and is linked together with magnetic pole 2, speed measuring device rotor 4.The connection of other parts is with embodiment 1.

Referring to Fig. 3, adopt its power shaft 6 of planetary cycloid tooth reducing gear and magnetic pole 2, speed measuring device rotor 4 to install and be linked together in this embodiment.The connection of other parts is with embodiment 1.

The device connected mode of the utility model and load was both horizontal also can be vertical.

The utility model thereby has following advantage owing to electromagnetism slip clutch and epicyclic type mechanism are made up in aggregates at same central axis:

1, install and use simple;

2, compact conformation, it is few to take material, weight saving, cost is low;

3, take up room little, sturdy and durable;

4, overload capacity is strong;

5, speed adjustable range is wide, good speed adjustment features, and speed regulating control power is little, is convenient to Automatic control, team control, remote control.
