Abstract
A kind of buncher belongs to drive technology field, mainly solves traditional speed change gear speed-change process and runs out of steam, and produces interim card, the jiggly problem of speed change.The utility model is by gearbox case, speed changer end cap, main shaft, flywheel, power input module, steel ball component, power output component, input stator, output stator, roller gear, eccentric gear composition.Under spindle assemblies fixing situation, flywheel is by the presence of external force, around main axis, power input module is driven, power input module drives steel ball component to rotate, and steel ball drives power output component, power output component drives casing assembly to rotate, being rotated during speed change by roller gear drives eccentric gear to rotate, and it is steady smooth in speed-change process so as to realize to drive steel ball component angle change, solves the problems, such as traditional gear speed change interim card.Available for the speed governing such as bicycle, electric car and automobile field.
Description
Technical field
The utility model relates to transmission device, particularly a kind of buncher.
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, the change of gear needs multiple sprocket wheels to coordinate, and in general, which refers to group speed change, the change of 5-7 shelves
Speed, then mutually in requisition for 5-7 sprocket wheel cooperating, substantially increase the complexity of variable ratio drive system.And the regulation of gear
It is one-level one-level transition, produces that transition is unsmooth and the problem of pause and transition in rhythm or melody.
The content of the invention
Goal of the invention：In view of the above-mentioned problems, overcoming above-mentioned deficiency, a kind of buncher is developed, realizes speed-change process
It is steady smooth.
Technical scheme：A kind of buncher, it is characterised in that including gearbox case, output cam, output retainer,
Export bail, output stator, main shaft, idle pulley, steel ball component, input stator, eccentric gear, cylindricality gear, input cam, drive
Dynamic flywheel, speed changer lid, flywheel, input bail, input retainer composition, the steel ball component is by steel ball and pin group
Into steel ball is rotatable by axle of pin, and steel ball component is arranged between output stator and input stator in pairs, and steel ball component can be put
Dynamic to form angle with main-shaft axis direction, idle pulley, output stator and input stator are installed on main shaft, and output stator and input are fixed
Sub rotatable, idle pulley is in contact with steel ball, and output cam is in contact with gearbox case inner bottom part, and output cam, output are kept
Frame is in contact, and output retainer is in contact with output bail, and output bail is in contact with steel ball surface, and steel ball surface is simultaneously
Contacted with input bail, input bail contacts with input retainer, and input retainer is in contact with input cam, and input is convex
Wheel is connected with driving flywheel, and driving flywheel is connected with flywheel, and cylindricality gear is arranged on main shaft, eccentric gear and columnar tooth
Wheel is meshed, and eccentric gear is connected with input stator.
Further, it is described go out to export retainer, input retainer is plastic material.
Further, the steel ball surface of the steel ball component scribbles lubricating oil.
Preferably, the steel ball component quantity is 3-6 pairs.
The utility model principle：Under spindle assemblies fixing situation, flywheel is turned by the presence of external force around main shaft
It is dynamic, driving flywheel is driven, driving flywheel drives input cam to rotate, and in the presence of retainer is inputted, drives input bail
Rotate, bail, which rotates, causes steel ball component to rotate, while drives the output bail on other one side to rotate, and drives output to keep
Frame component movement, output cam is driven to rotate, output cam drives casing assembly to rotate, so as to realize the rotation of whole wheel.
Being rotated during speed change by roller gear drives eccentric gear to rotate, and drives steel ball component angle change, steel ball invariablenes turning speed, steel ball
When assembly angle changes, the radius for inputting bail and exporting contact point to the steel ball component axle of bail and steel ball occurs
Corresponding change, corresponding linear velocity changes, so as to realize stable speed change.
Beneficial effect：Compared with prior art, the utility model has the advantages that realizing stepless shift function by frictional force,
Compact-sized, speed change is steadily smooth, and speed change implements response response, and no impact is noiseless.Relative to traditional Chain conveyer speed change
Device, the utility model greatly reduce number of components, without multiple sprocket wheels, simplify overall structure, save overall volume and weight,
Reduce cost.
