Abstract
The invention discloses a kind of drive mechanism, the drive mechanism includes output cam, retainer component, bail, steel ball component and input cam.Steel ball component both sides are arranged symmetrically bail, retainer component and input and output cam.Input cam rotation drives retainer component roller to rotate, roller drives bail to rotate, the opposite side of bail contacts with the steel ball of planetary position, bail drives steel ball rotation, steel ball rotation drives output end bail to rotate, bail drives retainer component and output cam to rotate, and reaches transmission effect.This drive mechanism is mainly used in bicycle buncher, stable drive, no pause and transition in rhythm or melody and can realize single-direction transmission, is slipped after being prevented when going up a slope.
Description
Technical field
The present invention relates to a kind of drive mechanism, particularly a kind of frictional drive structure.
Background technology
Bicycle, the transmission device of electric car typically use Chain conveyer, have reliability height, drive mechanism simply excellent
Point.Popular bicycle has shift speed change function mostly in recent years, conveniently adapts to the bicyclist of all ages and classes and different road conditions
Power transmission need, the gear digit of more high-grade bicycle is more.
But for Chain conveyer, shock loading is big in its transmission process, is not filled by Chain conveyer gear shift lubrication
Phenomenon is slipped after being also easy to produce when being short of power when being also easy to produce noise in the case of point, and pause and transition in rhythm or melody can be produced to influence experience of riding, and going up a slope,
Cause potential safety hazard.
The content of the invention
Goal of the invention：In view of the above-mentioned problems, overcome above-mentioned deficiency, there is provided a kind of drive mechanism, the drive mechanism is by rubbing
Wipe and realize the transmission of power, it is quiet, steady, without pause and transition in rhythm or melody phenomenon, the unidirectional delivery of power is realized by ratchet, solves to slip after going up a slope
The problem of.
Technical scheme：A kind of drive mechanism, including output cam, retainer component, bail, steel ball component and input are convex
Wheel.Steel ball component includes nut, bearing pin and steel ball, and bearing pin both ends are provided with screw thread, can by steel ball axial restraint, steel ball by nut
Along bearing pin rotation, steel ball component is 6 arrangements in pairs.The retainer component includes retainer, roller, and roller is justified along retainer
Circumferential direction is uniformly distributed, and roller can be along retainer radial rotating.The output cam, bail and input cam and retainer group
Part contact surface is provided with end face ratchet, and ratchet is clockwise, output cam and input cam is provided with keyway.The steel ball component
Both sides are arranged symmetrically bail, retainer component and input cam, output cam.
Further, the retainer material of the retainer component is plastics.
Further, the bail material is high-abrasive material.
Further, the roller of the retainer component is 16, is distributed on retainer circumference.
Further, the retainer component is also installed in retainer including spring, both ends of the spring and bail end face
Ratchet face perpendicular contact.
The principle of the invention：Input provides a turning moment by the keyway of input cam, when direction of rotation is suitable
During hour hands, input cam end face ratchet can drive the roller in retainer to rotate, and same roller drives the end above bail
Face ratchet rotates, and the opposite side of bail contacts with the steel ball of planetary position, and bail drives steel ball rotation, and similarly, steel ball is certainly
Turn to drive output end bail to rotate, bail drives plastic cage and output cam to rotate, and reaches transmission effect.If input
Cam rotates backward, and roller can be stuck on cam and can not rotate, then is unable to reach transmission effect.
Beneficial effect：Compared with prior art, it is an advantage of the invention that：It is driven using frictional force, solves sprocket wheel
Shock loading is strong in transmission process, and noise is big, compact-sized the problem of pause and transition in rhythm or melody, easy to maintain, passes through ratchet and realizes unidirectional pass
It is dynamic, solve because slipping phenomenon after caused by being short of power.

Embodiment
Be below specific embodiment, the present invention is furture elucidated, it should be understood that this embodiment be merely to illustrate the present invention and
Limitation the scope of the present invention is not used in, after the present invention has been read, various of equal value shapes of the those skilled in the art to the present invention
The modification of formula falls within the application appended claims limited range.
A kind of drive mechanism as shown in Figure 1, including drive mechanism include output cam 1, retainer component 2, bail 3,
Steel ball component 4 and input cam 5.Steel ball component 4 includes nut, bearing pin and steel ball, and bearing pin both ends are provided with screw thread, will by nut
Steel ball axial restraint, steel ball can be arranged in pairs along bearing pin rotation, 6 steel ball components.Retainer component as shown in Figure 5 includes keeping
201,16 frame, roller rollers 201 are uniformly distributed along retainer circumferencial direction, and roller 201 can be along retainer radial rotating；Such as figure
3rd, output cam 1 shown in Fig. 4, bail 3 and input cam 5 are provided with end face ratchet, ratchet direction with retainer component touch face
For clockwise, output cam 1 and input cam 5 are provided with keyway.As shown in Fig. 2 the ratchet face of input cam 5 and retainer group
Part 2 is in contact, and retainer component 2 first contacts with the ratchet face of bail 3, and bail 3 contacts with the steel ball of steel ball component 4, steel ball
Contacted with output end bail 3, output end bail 3 contacts with output end retainer component 2, output end retainer component 2 with
The ratchet face of output cam 1 contacts.Input provides a turning moment by the keyway of input cam, when direction of rotation is suitable
During hour hands, input cam end face ratchet can drive the roller in retainer to rotate, and same roller drives the end above bail
Face ratchet rotates, and the opposite side of bail contacts with the steel ball of planetary position, and bail drives steel ball rotation, and similarly, steel ball is certainly
Turn to drive output end bail to rotate, bail drives plastic cage and output cam to rotate, and reaches transmission effect.If input
Cam rotates backward, and roller can be stuck on cam and can not rotate, then is unable to reach transmission effect.
