Abstract
The utility model relates to an improved generation motorcycle infinitely variable belt pulley, its main technical characterized in that: the outer edge of the hub (1) and the powder metallurgy sliding sleeve (2) in the movable driven disc (4) adopt a polygonal plane and arc plane multiple matching modes to transmit torque, and during assembly, the powder metallurgy sliding sleeve (2) and the movable driven disc (4) can adopt static matching. Transition fit can also be adopted to realize the integration of the two, so that the screw fixing for the hole opening is adopted. The hub (1) and the powder metallurgy sliding sleeve (2) can only do axial movement and can not do rotary movement. The utility model discloses simple structure, processing is convenient, and transmission torque is steady, reliable, and light in weight, and advantage such as few with the material, long service life.
Description
The utility model relates to the centrifugal stepless speed changes devices of a kind of machine power transmission, refers more particularly to a kind of motorcycle stepless speed pulley.
In existing technology, the series motorcycle belt pulley has 3 kinds of kinds of drive, and a kind of is three claw convolutions, the defective that this old-fashioned belt pulley exists is a discontinuity, cause belt impaired, the wheel disc portion produces circular runout, and angle increases, the surface of contact of transmission pulley reduces, rolling appears in belt, damage belt, and manufacturability is poor, maintenance difficult needs often to refuel and special-purpose dismantling device.Second kind is steel ball lead key formula, to utilize steel ball or needle roller be spindle guide to and carry-over moment, its maximum shortcoming is axially directed poor performance, the guiding contact is too little, so very easy to wear, and clamping stagnation and circular runout appear, in addition, the axially directed half slot surface Machining of steel ball and needle roller precision is difficult to control, processing difficulties.The third is a Chinese patent, the patent No. 90216314.0, and involved powder metallurgy sliding sleeve and roll the Connecting format that pin cooperates the hole on the wheel hub in this patent, and the powder metallurgy spline housing cooperates wheel hub spline Connecting format; Roll the pin formula because the degree of depth in hole on the wheel hub has certain requirement, so the wheel hub cylindrical can't dwindle by original size (φ 34) again, in addition the wheel hub outer round surface be had the certain rigidity requirement, need heat treatment, so with material aspect requirement height.
It is good that the purpose of this utility model provides a kind of steering capability, and driving torque is reliable.Few motorcycle stepless speed pulley axially weares and teares.
The purpose of this utility model is to realize like this, it is by mobile driven disc, driven disc, spring, spring seat, draw-in groove, wheel hub is formed, its major technique is characterised in that: wheel hub outer rim and the powder metallurgy sliding sleeve in mobile driven disc adopt polygon plane and arc, the multiple fit system carry-over moment in plane, wherein powder metallurgy sliding sleeve and mobile driven disc can adopt stationary fit, also can use transition fit, adopt transition fit all to need perforate on powder metallurgy sliding sleeve and mobile driven disc, directly fixing with fastening piece, also the powder metallurgy sliding sleeve can be designed to take on arm-type, moving admittedly from end face again with fastening piece.
The utility model has following advantage compared to existing technology:
1, simple in structure, easy to process, easy to maintenance.
2, the belt pulley carry-over moment is steady, reliable, thus the working life of having improved belt pulley and belt.
3, in light weight, few with material.
Fig. 1 is the utility model half sectional view;
Fig. 2 is that the wheel hub in the utility model cooperates the A-A schematic representation with powder metallurgy sliding sleeve polygonal;
Fig. 3 is that wheel hub cooperates the A-A schematic representation with powder metallurgy sliding sleeve arc, plane in the utility model.
Below in conjunction with accompanying drawing the utility model embodiment is further described: the utility model is on the basis of former 90216314.0 patented technologies, further done improvement, both having overcome the former pin that rolls cooperates the degree of depth in the hole on powder metallurgy sliding sleeve (2) belt pulley hub (1) to have requirement and outer round surface to have certain rigidity, it is big to have overcome multiple spline hub matching spline sliding bush type belt pulley difficulty of processing again, the machining accuracy height, the cost height.Thereby changed its processibility, manufacturing process is further simplified, and the material aspect also reduces to greatest extent, and whole belt pulley weight is reduced to 0.71 kilogram weight by original 1 kilogram.
Embodiment 1: see Fig. 2 for details, powder metallurgy sliding sleeve (2) cooperates wheel hub (1) outer rim polygon plane centering pilot driving torque.
Embodiment 2: see Fig. 3 for details, powder metallurgy sliding sleeve (2) cooperates wheel hub (1) outer rim arc plane and the plane fit system carry-over moment that combines.
No matter the utility model is by implementing 1 manufacturing or can both reaching its effect by embodiment's 2 manufacturing.During installation, powder metallurgy sliding sleeve (2) and mobile driven disc (4) are stationary fit.Also can adopt transition fit to connect, adopt transition fit, can go up perforate at powder metallurgy sliding sleeve (2) and mobile driven disc (4), and be fixed with fastening screw trip bolt.Another kind of scheme is to adopt shoulder arm-type powder metallurgy sliding sleeve (2), and is fastening with screw from end face.Both can only move axially wheel hub (1) and powder metallurgy sliding sleeve (2), can not rotate, and need guarantee that mobile driven discs (4) drive under external force that powder metallurgy sliding sleeve (2) opens or should be flexible when closing up, and catching phenomenon must not be arranged.
Claims (3)
1, a kind of modified model motorcycle stepless speed pulley, it comprises mobile driven disc, driven disc, spring, spring seat, draw-in groove, wheel hub, it is characterized in that: wheel hub (1) outer rim and adopt polygon plane and arc, the multiple fit system in plane at mobile driven disc (4) lining powder metallurgy sliding sleeve (2).
2, motorcycle stepless speed pulley according to claim 1 is characterized in that: powder metallurgy sliding sleeve (2) can adopt stationary fit with mobile driven disc (4); Also can adopt transition fit.
3, motorcycle stepless speed pulley according to claim 2, it is characterized in that: powder metallurgy sliding sleeve (2) adopts transition fit with mobile driven disc (4), can go up perforate at powder metallurgy sliding (2) and mobile driven disc (4), and use fastening piece stop; Also powder metallurgy sliding sleeve (2) can be processed into the arm-type angle of shoulder from end face fastening piece stop.
