Abstract
The utility model relates to a cycloidal planet speed reducer used for mechanical transmission, which is mainly composed of an input shaft, an output shaft, inner cycloidal wheels, outer cycloidal wheels, rolling bodies, balance blocks, etc. The utility model is characterized in that two outer cycloidal wheels which are fixedly connected into integration trough connecting screw bolts are meshed with two inner cycloidal wheels through two groups of rolling bodies, and each rolling body is correspondingly fixed by a holder which is matched with the rolling body. The utility model has the advantages of high transmission ratio, high transmission efficiency, low noise, small size, etc.
Description
The utility model is the cycloid in planet retarder that a kind of mechanical transmission is used.
As is well known, present general cycloid in planet retarder, the form that generally adopts the locking pin tooth to be meshed with two epicyclodial wheels, two epicyclodial wheels are installed on the rotary arm bearing.Therefore some complexity seems with regard to its structure.Volume is bigger, and because its output mechanism adopts pin-type load, column pin hole has limited the size of rotary arm bearing, must have influence on the operating life of rotary arm bearing, simultaneously, because the form with slip is meshed between the epicyclodial wheel gear teeth and the pin tooth that is installed in the housing, resistance is bigger, so transmission efficiency is on the low side relatively, and this kind retarder single staged transmission ratio scope is still big inadequately.
The purpose of this utility model is to provide a kind of novel cycloid in planet retarder, makes it to compare with present same category of device, and is progressive to some extent technically, obtains transmission effect preferably in the use.
According to above-mentioned purpose, technical solution adopted in the utility model is that the sliding friction that becomes cycloid wheel wheel between cog is rolling friction, be to be meshing with each other by rolling element between epicyclodial wheel and the hypocycloid wheel, thereby promptly reduced friction factor, will improve transmission efficiency again.
Figure of description is a concrete structure schematic representation of the present utility model, as seen from the figure, the utility model mainly is by input shaft 1, eccentric shaft 2, epicyclodial wheel 3 and 9, rolling element 4 and 8, hypocycloid wheel 5 and 7, end cap 6, rotary arm bearing 10, output shaft 11, equilibrium block 12 and 14, support 13, the attachment bolt heart, output rotating disk 16, housing 17 component such as grade constitute, wherein input shaft 1 has a style of one's own with eccentric shaft 2, be same part, two connect firmly all-in-one-piece epicyclodial wheel 3 and 9 by attachment bolt 15 and are meshed with two hypocycloid wheels 5 and 7 by rolling element 4 and 8, each rolling element by retainer with matching with its position relative fixed, input end hypocycloid wheel 5 is welded on the housing 17, output terminal hypocycloid wheel 7 be installed in output shaft 11 on the output disc 16 of same component, input shaft 1 and output shaft 11 respectively are provided with the rotary arm bearing 10 of oneself, equilibrium block 12 and 14 is fixedly mounted on the input shaft 1, in the gear-profile curve is designed to, epicycloid.
According to said structure, the feature that newly-designed retarder had is: two epicyclodial wheels 3 and 9 are connected firmly by attachment bolt 15 and are integral, be meshed with two hypocycloids wheel 5 and 7 by two groups of rolling elements 4 and 8, each rolling element by the retainer that cooperates with it with its position relative fixed.
The said rolling element in front can be a cylindrical body, also can be spheroid.
The utility model has been cancelled pin-type load output mechanism in the past, and change the sliding friction of common epicyclodial wheel into rolling friction, realized theoretic " no friction driving ", therefore, the rolling friction cycloid in planet retarder of designing has that volume is little, noise is low, the transmission efficiency height, compact structure, advantages such as long service life.Can be widely used in mine, metallurgy, petrochemical industry, light industry and food, textile printing and dyeing, lifting transportation, various mechanical transmission occasions such as pharmaceutical machine are as a kind of novel retarder, in can replacing, low power other various retarders use.
Concrete structure and situation shown in the drawings during the utility model design are basic identical, and it is cylindrical wherein making epicyclodial wheel and hypocycloid take turns intermeshing rolling element.
