Problems solved by technology

However, since the fan is connected to the output shaft of the reducer, the rotation of the fan will drive the reducer to shake a lot during operation, which will cause the reducer to shake relative to the grid and generate a lot of noise

Abstract

The invention discloses a speed reducer, which is arranged on a cooling tower. The output shaft of the speed reducer is connected with a fan. A support frame and a net are arranged on the upper part of the cooling tower. The speed reducer is arranged on the support frame; it includes an upper casing and The lower casing; the output shaft is arranged on the lower casing; the connecting device is used for fixing the limit of the reducer to the bracket; the shock absorbing seal has a sealing part, a shock absorbing part and is used for connecting the shock absorbing part and the The connecting part of the sealing part, the sealing part is placed at the joint of the upper and lower casings, and the upper and lower surfaces are respectively sealed and matched with the upper and lower casings; the shock absorbing part is arranged between the lower casing and the bracket to realize deceleration shock absorber operation. The present invention can realize the shock absorption of the reducer, avoid the possibility of noise generated by the reducer during operation, and at the same time strengthen the sealing effect of the connection between the upper and lower casings, prevent leakage after long-term use, and have a long service life.

Description

technical field [0001] The invention belongs to the technical field of reducers, in particular to a reducer. Background technique [0002] The current cooling tower reducer is usually a combined assembly structure, and the upper and lower shells are connected to each other by screws and other structures. However, the sealing of the connection between the upper and lower casings has always been a long-term problem. After long-term use, the sealing performance is prone to failure, causing the reducer to leak, the internal lubricating oil is gradually reduced, and the external water will enter the lubrication chamber, seriously affecting the reducer. service life. [0003] And when the reducer is connected to the cooling tower, the usual method is to connect the reducer housing to the grid frame on the upper part of the cooling tower through screws. However, since the fan is connected to the output shaft of the reducer, the rotation of the fan will drive the reducer to shake ...
