Abstract

The utility model relates to a stepless speed change skid-proof band which comprises a band body (8) and skid-proof layers (4) with convex veins, wherein the skid-proof layers (4) with convex veins are arranged on working surfaces on both sides of the band body. The utility model is characterized in that the bottom of the band body (8) is evenly provided with geometric graphics with bulges (1), grooves (5) and smooth transition. The utility model not only has the advantages that the stepless speed change skid-proof band has simple structure and drainage action, the friction force is increased, slippage and rotation loss can be avoided, the band is prevented from dropping off and abrading, etc., but also has the advantages that the stepless speed change skid-proof band can be suitable for driving buffer strain with different speeds, driving heat generation can be prevented or reduced, thermal fatigue damage can be lowered, the service life of the driving belt is prolonged, the oil production cost is reduced, the production efficiency is improved, etc.

Description

The stepless change non-skid band

The utility model belongs to driving belt, particularly a kind of stepless change non-skid band.

At present; the driving belt that uses on the oil-field oil pumper all is common V-type driving belt usually, and this driving belt exists transmission efficiency low, and hysteresis loss is big; working life is short, particularly often occurs skidding at the rainy day driving belt throwing switch, falling band even blow band causing and stopping preceding or phenomenon such as shutdown.For this reason, our Development and design the anti-skidding V-belt of used for oil-field oil pumper and to have declared this band of patent (patent No. is 94217326.0) mainly be evenly to be provided with regularly arranged protruding pattern on the working surface of existing V-type belt body both sides.Though having drainage, it increases frictional force, but avoid skidding, throwing switch phenomenon, but it still exists driving belt life heat leakage in transmission process slow, and fatigue damage is big, and working life, relatively low grade was not enough.

The purpose of this utility model is: design provides a kind of simple in structure at the deficiencies in the prior art, both had drainage, increase frictional force, can avoid skids throws switch, when guaranteeing the driving belt proper functioning, driving belt is reduced give birth to heat, reduce fatigue damage, improve the stepless change non-skid band in working life.

The utility model is achieved by following manner: a kind of stepless change non-skid band, comprise the skidresistant course 4 of the protruding pattern of uniform setting on the belt body 8 that is made ofjoint group layer 6,buffer layer 7,strength layer 2,compression layer 3 and the both sides working surface thereof, it is characterized in that: belt body 8 bottoms evenly are provided with the geometric form of projection 1 and groove 5 and rounding off.Here said geometric form can be to go up lower semi-circle or go up the projection 1 of lower trapezoid and the geometric form of groove 5 and rounding off (similar wave), can certainly be that other is as triangle or square, the projection 1 of rectangle and the geometric form of groove 5 and rounding off (sawtooth like) up and down up and down.The geometric form of this projection 1 and groove 5 and rounding off can make driving belt adapt to the transmission buffering strain of variable speed in transmission process, significantly reduce transmission and give birth to heat, and heat fatigue damage etc., significantly improve the working life of driving belt, thereby reduced cost for oil production, improved manufacturing efficiency.

The utility model is compared with prior art, simple in structure except that having, drainage is arranged, increase frictional force, can avoid skids throws switch and falls band and burn outside the advantage such as band, also has the transmission buffering strain that can adapt to variable speed, prevent from or reduce to give birth to heat and heat radiation is slow, reduce the thermal fatigue loss, improve driving belt working life, reduce cost for oil production, characteristics such as enhance productivity.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model sectional view.And this figure is the sectional view of joint group (promptly three groups), and it can manufacture single or joint group (comprising two groups or more) structure according to user's needs.

Fig. 3 is the utility model working state schematic representation on belt pulley.

Among the figure: 1 projection, 2 strength layers, 3 compression layers, 4 skid resistant courses, 5 grooves, 6 joint group layers, 7 buffer layers, 8 belt bodies, 9 belt pulleys.

Most preferred embodiment of the present utility model, as Figure 1-3.A kind of stepless change non-skid band, comprise the skidresistant course 4 of the protruding pattern of uniform setting on the belt body 8 that is made ofjoint group layer 6,buffer layer 7,strength layer 2,compression layer 3 and the both sides working surface thereof, it is characterized in that: belt body 8 bottoms evenly are provided with the geometric form of projection 1 and groove 5 and rounding off.Here said geometric form can be to go up lower semi-circle or go up the projection 1 of lower trapezoid and the geometric form of groove 5 and rounding off (similar wave), can certainly be that other is as triangle or square, the projection 1 of rectangle and the geometric form of groove 5 and rounding off (sawtooth like) up and down up and down.The geometric form of this projection 1 and groove 5 and rounding off can make driving belt adapt to the transmission buffering strain of variable speed in transmission process, significantly reduces frictional heat and heat dissipation is slow, and the heat fatigue damage etc.Significantly improve the working life of driving belt, thereby reduced cost for oil production, improved manufacturing efficiency.Present technique can manufacture single or the joint group structure according to user's needs during fabrication, and joint group comprises two groups or more as three groups, four groups, five groups or the like, and Fig. 2 provides is three groups structural type.In addition, the skidresistant course 4 of the protruding pattern that is provided with on the belt body 8 both sides working surfaces can be chevron shaped decorative pattern or some face decorative pattern etc., can certainly be other decorative pattern etc.
