The industries such as lifting transport are widely used.The structure of majority cycloidal-pin gear speed reducer at present are as follows: input shaft is connected to the motor,
Drive entire retarder operation.Input shaft does high speed centrifugation rotation and drives Cycloidal Wheel rotation, and two Cycloidal Wheels are in eccentric 180 ° of cloth
It sets, Cycloidal Wheel is realized deceleration transmission and spread out of movement by output panel by needle roller and needle tooth engagement.
However, currently, the pinwheel of cycloidal-pin gear speed reducer is all monolithic construction, since lubricant effect is poor, Ge Geling
Component wear is serious, and common failure is that spot corrosion, gluing and needle roller and pin fracture, are glued, fatigue crack, the cracking of pinwheel
Deng.Application No. is a kind of cycloidal-pin gear speed reducer is disclosed in 201611127691.7 patents, by using in each needle tooth shaft
On load onto the needle tooth of bearing structure to reduce the coefficient of friction between Cycloidal Wheel and needle tooth, improve transmission efficiency, reduce cycloid
Abrasion between wheel and needle tooth.But there are still following shortcomings in use for monoblock type pinwheel configuration:
1, the cycloidal-pin gear speed reducer of monoblock type pinwheel configuration is not easy to dismantle in use, and lubricating grease can only be smeared
It outside retarder, then penetrates into inside retarder and is lubricated, so that lubricant effect is poor, frictional force is big, leads to each zero
Part is easy to appear failure.
2, the cycloidal-pin gear speed reducer of monoblock type pinwheel configuration is difficult to be replaced after needle roller is worn in use, holds
It easily leads to retarder complete machine to scrap, causes greatly to waste.
3, the cracked necessary integral replacing in pinwheel abrasion part of the cycloidal-pin gear speed reducer of monoblock type pinwheel configuration, increases
Production cost is added.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, a kind of split type needle of fastening means simplicity is provided
The cycloidal-pin gear speed reducer of wheel.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of cycloidal-pin gear speed reducer, including input shaft, Cycloidal Wheel, pinwheel, output panel, it is characterised in that: the pinwheel
To be split type, several sub- pinwheels that it is 360 ° that it, which is by the sum of angle of circumference, are spliced to form complete pinwheel configuration, adjacent sub- needle
Mating surface between wheel is vertical with pinwheel cross section or out of plumb；The sub- pinwheel is to be meshed by needle roller with Cycloidal Wheel,
Its arc end surface is equipped with the affixed mechanism for realizing the splicing and partition of sub- pinwheel.
The sub- pinwheel is 2 or 3.
The arc end surface of the sub- pinwheel, which is equipped with, realizes that sub- pinwheel splicing and the affixed mechanism of partition refer in every sub- needle
The outside for taking turns arc end surface is equipped with the component for positioning and fixing for sub- pinwheel accordingly.
The positioning and fixed component refer to that the outside of sub- pinwheel arc end surface is equipped with corresponding boss, open on boss
There is the dowel hole for realizing positioning finger setting and realizes the fixed through-hole of bolt.
The positioning and fixed component refer to that the outside of sub- pinwheel arc end surface is equipped with corresponding boss, boss following table
Face is provided with the convex cone platform or concave cone platform for realizing conical surface positioning.
Compared with prior art, the invention has the following advantages:
1, the pinwheel of cycloidal-pin gear speed reducer of the invention is fastened by several sub- pinwheel connections, overcomes monoblock type
Shortcoming existing for pinwheel configuration cycloidal-pin gear speed reducer, the cycloidal-pin gear speed reducer of split type pinwheel configuration is in use process
In, sub- pinwheel can be removed, lubricating grease is applied on retarder inner body, substantially improve lubricant effect, reduce friction
Power, the service life of each components in prolonged deceleration device.
2, the cycloidal-pin gear speed reducer in the present invention is dismantled pinwheel after needle roller abrasion and is carried out more to needle roller in which can be convenient
It changes, guarantees the normal operation of retarder.
3, when part is cracked after the pinwheel abrasion in the present invention and damages, corresponding sub- pinwheel can be only replaced, effectively
Ground reduces production cost.
4, the cycloidal-pin gear speed reducer of split type structure of the present invention, fastening and disassembly mode are easy, and can be using difference
Positioning method reach positioning accuracy；Production cost is low, practical, and popularization and application foreground is good.
