Abstract

The utility model provides an axial-mounting cycloidal speed reducer which is the other driving machine model of a cycloidal speed reducer, and the utility model replaces the original cylindrical gear axial-mounting speed reducer, and is widely applied to bucket type lifters, belt conveyers and scraper conveyers in the industries of grain, food, fodder, etc. Compared with the original axial-mounting machine model, the utility model has the advantages that the weight is reduced by from 25 to 35 percent, the external size is reduced by from 20 to 40 percent, the service life is extended by 60 percent and the noise is reduced by from 3 to 5 db.

Description

Axially mounted cycloidal reducer
The utility model relates to the speed reducer mechanical field, a kind of novel axially mounted cycloidal reducer.
Be extensive use of the shaft-mounted speed reducer of cylindrical gears on modern noria, belt conveyor and the scraper conveyor.This is can adopt the mounting type that directly is assemblied on the matched host machine power input shaft because of shaft-mounted, and has saved connection annex and speed reducer mountion plate between the two.But the shaft-mounted speed reducer of cylindrical gears has many places not fully up to expectations in actual use: the 1. serious leakage of oil of high speed shaft and influenced working efficiency greatly; 2. volume is big, and heaviness is brought bigger trouble to installation; 3. the life-span low, noise is big.
The utility model purpose provides that a kind of sealability is reliable, boundary dimension is little, in light weight, noise low and the axially mounted cycloidal reducer of long service life.
According to analysis, research to existing many speed reducers, think that few tooth is poor, advantages such as the cycloidal-pin wheel planetary speed reducer that particularly is most widely used possesses in light weight, and low noise and life-span are long, but owing to structural reason it can't be applied in always shaft-mounted on.The utility model adopts following technological scheme: the input belt pulley connects with capacity eccentric bearing, belt pulley is bearing on the front cover by bearing, the output shaft two ends are positioned in front cover and the belt pulley endoporus with bearing respectively, it is characterized in that through hole is arranged in the output shaft, make retarder be installed in the matched host machine input shaft and be positioned on the fixing pin by suspension plate, pin wheel housing and front and rear cover are connected into one.
The utility model is shaft-mounted than cylindrical gears: good seal performance, and weight can reduce 25~35%, and boundary dimension can reduce 20~40%, and the life-span increases by 60% approximately, and noise reduces by 3~5db, therefore can all replace former shaft-mounted speed reducer.
Accompanying drawing is the utility model embodiment's a structure principle chart.
With reference to accompanying drawing the utility model is illustrated in detail.
Mainly by input belt pulley [16], capacity eccentric bearing [12], cycloid wheel [9], pin gear axial pin type mechanism forms axially mounted cycloidal reducer, and wherein pin gear is made of pin wheel housing [21], needle pin [20] and pin gear sleeve [19].Output mechanism is made of straight pin [7], roller [8] and discoid output shaft [1].Be primarily characterized in that: 1. in the output shaft [1] through hole is arranged, retarder is installed on the matched host machine input shaft, the pin of uniform close-fitting [7] on its disk, output shaft [1] one end is bearing in sleeve [14] endoporus with bearing [18], the other end is bearing in the endoporus of end cap [5] with bearing [4], and the cylindrical of cover letter [14] is bearing in rear end cover [11] endoporus with bearing [13]; 2. import belt pulley [16] rear end cover [11] and connect one; 3. end cap [11], pin wheel housing [21] and front cover [5] connect one; 4. suspension plate [6] one ends connect with front cover together with gland, and the other end has a hole in order to be suspended on the locating stud.
Its working principle is: when belt pulley [16] rotation drives capacity eccentric bearing [12], so outer pin gear sleeve [19] engagement of the gear teeth of cycloid wheel [9] and pin tooth [20] relies on pin [7], roller [8] and plate-like input shaft [1] to realize power output.For making moving equilibrium, cycloid wheel [9] is two, and two capacity eccentric bearings then stagger according to 180 °.One spacer ring [10] is arranged between two cycloid wheel.Ring washer [2] is done the spacing of bearing [4].Suspension plate [6] connects with front cover with screw together with platen.Rubber oil sea [3], [15], [17] prevent oil leak.
