Embodiment Construction

[0014] Such as figure 1 As shown, the supporting body of the heavy-duty reducer includes a housing 1 and a transmission shaft 2. The transmission shaft 2 is arranged in the housing 1 and is connected and fixed to the housing 1 through a bearing. One end of the transmission shaft 2 is provided with a gear I12, The other end is provided with a gear II8, the gear I12 is connected with the transmission shaft 2 to form an integral structure; the gear II8 is connected and fixed with the transmission shaft 2 through the key pin 13; the inner side of the gear I12 is provided with a bearing I, and the inner side of the gear II8 is provided with a bearing II.

[0015] In this embodiment, the bearing I is a tapered roller bearing 4 , and the bearing II is a spherical roller bearing 5 . The inner side of the bearing I is provided with an oil seal I6, and the outer side of the bearing I is provided with a stop washer 10 and a cap 11 in turn; the outer side of the bearing II is provided wi...

Abstract

The invention relates to a heavy reducer supporting body which comprises a shell and a drive shaft. A gear I is arranged at one end of the drive shaft, a gear II is arranged at the other end of the drive shaft, and the gear I and the drive shaft are connected into an integral structure; the gear II and the drive shaft are connected and fixed through key pins. A bearing I is arranged on the inner side of the gear I, and a bearing II is arranged on the inner side of the gear II. An oil seal I is arranged on the inner side of the bearing I, and a lock washer and a cap are sequentially arranged on the outer side of the bearing I. A bearing cap is arranged on the outer side of the bearing II, an oil seal II is arranged between the bearing cap and the bearing II, and the gear II and the drive shaft are connected and fixed through three key pins which are evenly distributed on the outer circumference of the drive shaft. Compared with the prior art, the shaft end of the drive shaft is directly provided with the corresponding gear to form the integral structure, and the other end of the drive shaft and the corresponding gear are connected and fixed through the three evenly distributed key pins, so that the drive efficiency of the whole supporting body is improved, and transmitted torque is more balanced and stable; the heavy reducer supporting body is suitable for a large or heavy reducer.

Description

technical field [0001] The invention relates to the technical field of transmission machinery, in particular to a support body of a heavy speed reducer. Background technique [0002] At present, the existing transmission structure of the reducer generally includes a support body, a transmission shaft and a transmission gear, and the transmission shaft and the transmission gear are usually connected by key pins to transmit torque. For large or heavy reducers, due to the large transmission torque, if a key pin is used for connection, there will be problems of unbalanced transmission torque, instability, and low transmission efficiency, and the transmission parts of the reducer are easily damaged, resulting in the failure of the reducer. Reduced service life and reduced reliability. Contents of the invention [0003] The purpose of the present invention is to provide a heavy-duty reducer support body with high transmission efficiency. The transmission shaft is directly provi...
