Abstract
The utility model relates to a reducer, in particular to a gapless reducer. The gapless reducer comprises a box body, a worm is arranged in the box body and extends out of the box body to form an input end, and an assembly key is arranged on the input end. A worm gear vertically arranged with the worm in a crossing mode is arranged in the box body, and an output shaft is arranged in the worm gear. Two ends of the worm are respectively positioned with the box body through a support bearing, and the worm gear is contacted with the worm in a gapless mode. An oil filling hole is arranged in the upper portion of the box body, and an erosion resistant coating is coated outside the box body. The gapless reducer is compact in structure, capable of improving use performance and improving service life, strong in erosion resistance, and capable of improving transmission precision.
Description
Technical field
The utility model is a kind of speed reducer, particularly a kind of gapless speed reducer.
Background technique
Worm-gear speed reducer of the prior art, its worm couple are difficult to overcome the situation without sideshake in course of working, the existence of sideshake has greatly affected the precision of equipment.
Chinese patent 200520116829.4, a kind of reduction gears mechanism is disclosed, comprise sleeve, the input shaft that is provided with upper head plate, end plates and lower end sheet, the output shaft that is provided with out shaftgear, it comprises that also one connects the train of reduction gears of input shaft and output shaft, described train of reduction gears comprises the rotating shaft that is located between upper head plate and lower end sheet, the rotating shaft lower end is provided with and input shaft meshed gears one, and the rotating shaft upper end is provided with and goes out shaftgear meshed gears two.This complex structure, and adaptability is relatively poor, causes transmitting accuracy to descend, the stability that impact is used.
The model utility content
The utility model mainly is to solve the deficiencies in the prior art, compact structure, the tooth pitch difference of utilizing the different moduluses between the worm and gear tooth to form, by adjusting the axial position of worm screw in casing, make worm gear and worm screw realize the zero clearance of surface of contact, and the multimode number has guaranteed to remain between the surface of contact in the transmission process zero clearance, thereby realizes the gapless speed reducer of the transmission requirement of gapless speed reducer.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of gapless speed reducer, comprise casing, be provided with worm screw in the described casing, described worm screw forms input end to the casing extension, and described input end is provided with fitted key, be provided with in the described casing and the intersect worm gear of vertical distribution of worm screw, be provided with output shaft in the described worm gear, locate mutually by spring bearing and casing respectively at the two ends of described worm screw, and described worm gear contacts with the worm screw zero clearance, the top of described casing is provided with oil hole, and described casing scribbles anticorrosive coat outward.
As preferably, the left-hand end of described worm screw fixes by left end cap and casing, and the right side of described worm screw fixes by right end cap and casing, and described worm screw seals by oil sealing mutually with right end cap, and described spring bearing keeps off mutually with casing by back-up ring and connecing.
Therefore, the gapless speed reducer that the utility model provides, compact structure promotes usability, increases the service life, and has stronger corrosion resistance, improves transmission accuracy.
