Abstract
The utility model relates to a speed reducer, in particular to a worm gear speed reducer with an output mechanism. The worm gear speed reducer comprises a box body, an output shaft is inserted in the box body, a worm is sleeved on the output shaft, both ends of the worm are sleeved with bearings and are fixed together with the box body, both ends of the worm are respectively fixed with the box body via oil seals, and an output flange is sleeved at the head of the output shaft. The worm gear speed reducer with an output mechanism has simple structure, strong tightness and stable transmission, and the service life is prolonged.
Description
Technical field
The utility model is a kind of speed reducer, particularly a kind of worm-gear speed reducer with output mechanism.
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, and a kind of worm-gear speed reducer that improves the band output mechanism of good airproof performance in working life is provided.
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 with output mechanism; Comprise casing; Be plugged with output shaft in the described casing, be with worm gear on the described output shaft, the two ends of described worm gear are with bearing respectively and fix with casing; The two ends of described worm gear fix through oil sealing and casing respectively, and the head of described output shaft is with output flange.
As preferably, the afterbody of described output shaft keeps off mutually with worm gear through back-up ring and connecing, and is provided with pad between described back-up ring and worm gear.
As preferably, the socket separately of described output flange and output shaft is provided with positioning ring in the described oil sealing.
Therefore, the worm-gear speed reducer of the band output mechanism that the utility model provides, simple in structure, sealing is strong, and transmission steadily improves working life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
