The invention discloses a bearing device. The device comprises a conical roller bearing, an angular contact bearing, a spring, a bearing end cover and a press plate. The conical roller bearing is close to the inner side wall of a device shell, and an outer ring of the conical roller bearing is blocked by the inner side wall; the angular contact bearing is arranged at the side, away from the innerside wall, of the conical roller bearing; the spring is arranged at the side, away from the conical roller bearing, of the angular contact bearing, and the spring presses the outer ring of the angularcontact bearing in the direction of the inner side wall; the bearing end cover can be connected to the machine shell and press an outer ring of the angular contact bearing through the spring; the press plate is used for being connected with an inner ring of the angular contact bearing and a rotor. According to the bearing device, the conical roller bearing and the angular contact bearing are arranged in parallel and used for bearing the radial force and axial force of the rotor respectively. The bearing device is simple in structure, and stable operation of the rotor can be guaranteed. The invention further discloses a screw compressor with the bearing device.
Description
technical field [0001] The invention relates to the field of screw compressors, more specifically, to a screw compressor and a bearing device thereof. Background technique [0002] A screw compressor includes a male rotor and a female rotor. The driving device is connected with the front end of the male rotor to drive the male rotor to rotate. The male rotor meshes with the female rotor, and the male rotor drives the female rotor to rotate. Both the rear ends of the male rotor and the female rotor are provided with bearing devices. The bearing device is used to support the male rotor or the female rotor, and bear the axial force and radial force of the male rotor or the female rotor. The existing bearing device is composed of roller bearings, four-point contact ball bearings, angular contact bearings and other bearings, and has complex structure, high cost and poor stability. [0003] Therefore, how to design a bearing device with a simple structure and stable operation ...
