Clutch gearbox for slurry pump

Abstract

The invention discloses a clutch gearbox for a slurry pump, which mainly consists of an air clutch and a four-gear mechanical gearbox, wherein the air clutch is respectively connected with a power machine and the four-gear mechanical gearbox; the four-gear mechanical gearbox comprises a plurality of transmission shafts, and each transmission shaft is provided with a transmission gear; the air clutch is installed at the front end of a first shaft which is meshed and connected with a second shaft by transmission gears; the second shaft is also provided with the plurality of transmission gears; a third shaft is provided with transmission gears which have the number corresponding to that of the transmission gears on the second shaft and are meshed and connected with the transmission gears on the second shaft; a needle roller bearing is respectively arranged between each transmission gear on the third shaft and the third shaft; a meshing sleeve is respectively installed between every two transmission gears on the third shaft; the rear end of the third shaft is provided with a sun gear and a planetary gear set; a plurality of planetary gears of the planetary gear set are evenly distributed on a planet wheel frame and are meshed and connected with the sun gear; the planet wheel frame is connected with an output shaft; and an output end of the four-gear mechanical gearbox is connected with the slurry pump.

Description

technical field [0001] The invention belongs to the technical field of mud pumps, and mainly relates to a clutch gearbox for mud pumps. It is mainly used for the transmission of 1000HP mud pumps for oil field drilling and workover. Background technique [0002] In oil field drilling and workover operations, the mud pump set, which is an important equipment necessary for drilling and workover operations, puts forward the following requirements during use: [0003] 1. Portability requirements: The mud pump set will often move during use. As the power of the mud pump increases, the volume of the mud pump also increases, and the weight of the mud pump unit increases. Therefore, portability requirements are put forward for mud pump sets in drilling and repair operations. [0004] 2. Shifting requirements: During the working process of the mud pump group, according to the different working conditions in the well, corresponding shifting requirements are put forward for the strok...
