The utility model relates to a worm gear reducer, comprising a box body, a base, a worm wheel and a worm, wherein the worm wheel is sleeved on a worm wheel shaft; the worm wheel is meshed with the worm; two ends of the worm wheel shaft are respectively fixed on the box body through a first bearing and a second bearing; a front end cover of the worm wheel and a rear end cover of the worm wheel are arranged at two ends of the worm wheel shaft; worm wheel oil seal is respectively arranged between two ends of the worm wheel and the box body as well as the front end cover of the worm wheel; two ends of the worm are respectively fixed on the box body through a third bearing and a fourth bearing; two ends of the worm are provided with a front end cover of the worm and a rear end cover of the worm; and a worm oil seal is arranged between the worm and the box body as well as the front end cover of the worm. The worm gear reducer has the advantages of simple structure, good drive stationarity, good transmission efficiency, high accuracy and the like, and can save the installation space.

Description

A kind of worm-gear speed reducer
Technical field
The utility model belongs to field of mechanical technique, specifically relates to a kind of worm-gear speed reducer.
Background technique
Speed reducer is a kind of power transmission mechanism, utilizes the velocity transducer of gear, the winding number of motor (motor) is decelerated to desired winding number, and obtain the mechanism of larger torque.Be used for the mechanism of transferring power and motion at present, the application area of speed reducer is quite extensive.Almost can see its trace in the transmission system of various machinery, from boats and ships, automobile, the locomotive of the traffic tool, heavy machinery for building, the machining machine and tool that mechanical industry is used and automated production equipment, common household electrical appliances in the daily life, clock and watch etc.
Speed reducer is a kind of relatively accurate machinery, and the purpose of using it is to reduce rotating speed, increases torque.It of a great variety, model is different, and variety classes has different purposes.Retarder of a great variety can be divided into gear reducer, worm reducer and plane table thermoconductivity meter according to the transmission type; Can be divided into single-stage and multi-stage speed reducer according to transmission progression difference; Can be divided into cylinder gear speed reducer, cone gear reducer and circular cone-cylinder gear speed reducer according to gear shape; Setting type according to transmission can be divided into again expansion, flow deviding type and coaxial-type retarder.The main feature of worm-gear speed reducer is to have the reverse self-locking function, and larger reduction speed ratio can be arranged, and input shaft and output shaft be not on same axis, also not at grade.But general volume is larger, and transmission efficiency is not high, and precision is not high.
The model utility content
The defective that exists in order to solve existing design, the utility model provides a kind of worm gear worm-gear speed reducer.
A kind of worm-gear speed reducer, comprise casing, base, worm gear and worm screw, described worm gear set is located on worm-wheel shaft, described wormgear engaging worm, described worm-wheel shaft two ends are fixed on casing by clutch shaft bearing and the second bearing respectively, described worm-wheel shaft two ends are provided with worm gear front cover and worm gear rear end cover, and described worm gear two ends are provided with the worm gear oil sealing respectively and between casing, worm gear front cover; Described worm screw two ends are fixed on casing by the 3rd bearing and the 4th bearing respectively, and described worm screw two ends are provided with worm screw front cover and worm screw rear end cover, are provided with the worm screw oil sealing between described worm screw and casing, worm screw front cover.
Preferably, be connected by key between described worm gear and worm-wheel shaft.
Preferably, be provided with the O RunddichtringO between described worm gear front cover and worm gear rear end cover and casing.
Preferably, described casing top is provided with filler opening, and bottom half is provided with oil outlet.
Preferably, the overhanging end diameter of described worm screw is 30~40mm.
Preferably, the overhanging end length of described worm screw is 70~80mm.
The utility model is simple in structure, can save installing space, has simultaneously that transmission stability is good, transmission efficiency is good, the precision advantages of higher.
