Abstract
The utility model discloses a speed reducer with a buffer element. The speed reducer comprises a high-speed shaft and a middle shaft, wherein the high-speed shaft and the middle shaft are connected through a middle helical gear, and an elastic rubber pad is arranged between gear teeth of the middle helical gear. The speed reducer with the buffer element has the advantages that the elastic rubber pad is arranged between the gear teeth of the middle helical gear, the impact force received by the gear teeth can be buffered, the problem of load unbalance during teeth engagement because of processing assembly errors is solved, the bearing capability of the middle gear is enhanced, the service life of the speed reducer is prolonged, and in addition, the noise is reduced.
Description
Technical field
The utility model relates to speed reducer, is specifically related to a kind of speed reducer that is provided with shock absorber.
Background technique
Retarder is an enclosed transmission device independently between motor and the main shaft of hoister device; Be used for reducing rotating speed and increase torque; Existing retarder adopts conventional type of belt drive; Can occur because Gear Processing and the assembly error unbalanced phenomenon of load when causing a tooth engagement, not only noise is bigger, and causes the gear damage easily.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, and a kind of flimsy retarder of not allowing is provided.
For realizing above-mentioned purpose; The technological scheme of the utility model is a kind of speed reducer that is provided with shock absorber of design, comprises high speed shaft and jack shaft, and said high speed shaft is connected through middle helical gear with jack shaft; It is characterized in that, between the helical gear gear teeth in said centre, be provided with elastic rubber fitting.
Wherein, said elastic rubber fitting is arranged between the adjacent gear teeth through the rubber cushion groove.
Wherein, the said gear teeth comprise the revolver tooth and the right gear teeth that are oppositely arranged, and the said revolver tooth and the right gear teeth are installed in the wheel tube that is provided with on the above-mentioned middle helical gear.
Between the said revolver tooth and the right gear teeth, be provided with dividing plate and pass through bolt, nuts and washers connection.
The advantage and the beneficial effect of the utility model are: this speed reducer that is provided with shock absorber is through being provided with elastic rubber fitting between the gear teeth of intermediate gear; Can cushion the impact force that the gear teeth receive; The unbalanced problem of load during the individual tooth engagement that solved that error owing to processing and assembling causes; Strengthen the bearing capacity of intermediate gear, not only prolonged the working life of retarder, and reduced noise.
