In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
As shown in fig. 1, the utility model provides a scraper conveyor speed reducer output shaft assembly, including output shaft 10, first bearing 20, second bearing 30, third bearing 40, position sleeve 50, sealed lid 60 and round nut 70. The first end and the middle part of output shaft 10 all are located the inside of speed reducer casing, and the second end of output shaft 10 extends to the outside of speed reducer casing along transversely. The first end of the output shaft receives power from the input shaft via a bevel gear 11.
The first bearing 20, the second bearing 30 and the third bearing 40 are all sleeved at the first end of the output shaft 10. Inner rings of the first bearing 20, the second bearing 30 and the third bearing 40 are in transmission connection with the output shaft 10, and outer rings of the first bearing, the second bearing and the third bearing are fixedly connected with a speed reducer shell. Preferably, the first bearing 20 is a spherical roller bearing, the second bearing 30 is a single-row deep groove ball bearing, and the third bearing 40 is a single-row cylindrical roller bearing, which can realize stable and flexible rotation of the output shaft 10. When in use, the used lubricating grease is added into the three bearings periodically.
The locating sleeve 50 is sleeved on the middle part of the output shaft 10.
The sealing cover 60 is sleeved on the middle part of the output shaft 10 and is fixedly connected with the reducer casing through a bolt 62. The sealing cover 60 is used for sealing between the positioning sleeve 50 and the speed reducer casing, so that dust in air is prevented from entering the speed reducer.
