Abstract
The utility model relates to a reducer, in particular to a structurally simple reducer with an oil seal bearing, which comprises a box. A worm and a worm gear are arranged in the box and meshed with each other, one end of the worm is provided with an end seal mechanism, and the end seal mechanism includes a seal bearing, a shaft retainer ring and an oil seal cap, wherein the seal bearing is sleeved to the tail end of the worm, the seal bearing and the worm fixedly contact with the shaft retainer ring, the oil seal cap is arranged in the rear of the tail of the worm, and the oil seal cap is fixed to the box. The reducer is simple in structure and high in sealing performance, while the operational stability is increased.
Description
Technical field
The utility model is a kind of speed reducer, particularly a kind of speed reducer that has sealed-bearing simple in structure.
Background technique
Speed reducer of the prior art, the sealing between worm screw and the casing is not enough, and transmission stability is not good when causing the speed reducer running.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of speed reducer that has sealed-bearing is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of speed reducer that has sealed-bearing, comprise casing, the worm and worm wheel of establishing in the casing, described worm and worm wheel are meshed, and the end of described worm screw is provided with lateral end seal mechanism, and described lateral end seal mechanism comprises stuffing box bearing, shaft retaining ring and oil seal cover, described stuffing box bearing is enclosed within the tail end of worm screw, described stuffing box bearing and worm screw contact fixing with shaft retaining ring, described oil seal cover is located at the afterbody rear of worm screw, and described oil seal cover and casing fix.Lateral end seal mechanism makes the sealing of worm screw tail end increase widely, safeguards very convenient simultaneously.
As preferably, described shaft retaining ring and casing fix.
Therefore, a kind of speed reducer that has sealed-bearing that the utility model provides, simple in structure, sealing is strong, improves run stability.
