Abstract
The utility model relates to a speed reducer, in particular to a worm wheel and worm speed reducer. The worm wheel and worm speed reducer comprises a box body, wherein the box body is internally provided with a worm and a worm wheel; the worm is meshed with the worm wheel; both ends of the worm are respectively fixed with the box body through bearings; the left end of the worm is fixed in location through a check ring and the bearing positioned on the left end; the tail end of the worm is provided with an output flange; and the output flange and the box body are sealed through an oil seal. The worm wheel and worm speed reducer has the advantages of simple structure, high tightness, stable transmission and prolonged service life.
Description
Technical field
The utility model is a kind of speed reducer, particularly a kind of worm-gear speed reducer.
Background technique
Speed reducer of the prior art, the structure relative complex, and also sealing is relatively poor relatively, and unstable during use, product is produced certain influence.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the existing technology, and it is not good to have solved stability, provides a kind of raising to transmit worm-gear speed reducer stably working life.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of worm-gear speed reducer; Comprise casing, be provided with worm and worm wheel in the described casing, described worm and worm wheel are meshed; The two ends of described worm screw fix through bearing and casing respectively; The bearing of the left end of described worm screw through back-up ring and left end be maintenance mutually, and the afterbody of described worm screw is provided with output flange, and described output flange seals with casing through oil sealing mutually.
As preferably, the pairing wall box of the head of described worm screw is provided with oil seal cover, is provided with positioning ring in the described oil sealing.
As preferably, described output flange is located at the sidewall of casing.
Therefore, a kind of worm-gear speed reducer that the utility model provides, simple in structure, sealing is strong, and transmission steadily improves working life.
