Switching device for bearing seats

Abstract

The invention discloses a switching device for bearing seats. The switching device comprises a bearing cap, wherein an oil hole is formed in the top end of the bearing cap; a sealing cover is connected to the top end of the oil hole in a sleeving manner; two plunger holes are formed in the inner part of the bearing cap; a spring is fixedly connected to the interior of each of the plunger holes; afixing plate is fixedly connected to the upper part of each of the springs; a plunger is fixedly connected to one end of each of the fixing plates; a steel ball is arranged at the tail end of each ofthe plungers; a bearing seat is in bolted connection with the bottom of the bearing cap; a shaft is fixedly connected to the middle of the bearing cap and the bearing seat; an upper cover is arrangedin bearing cover; a bearing is rotatably connected with the interior of the upper cover; a bearing outer ring is arranged in the bearing; a bearing inner ring is arranged below the bearing outer ring;and a rolling body is clamped and connected between the bearing outer ring and the bearing inner ring. According to the switching device for bearing seats, the structure is simple, the operation is convenient, the service life is long, and the switching device is used for realizing the switching among bearing seats and quite suitable for long-time machining occasions.

Description

technical field [0001] The invention relates to the technical field of bearing seats, in particular to a bearing seat switching device. Background technique [0002] In mechanical equipment, bearings are widely used. It plays the role of fixing parts and reducing friction. The bearing seat as a fixed bearing also plays a great role in the installation of equipment. Common bearing seats are installed in steam turbine cylinders. The component used to support the bearing on the body or the foundation, the bearing seat is divided into: split bearing seat, sliding bearing seat, rolling bearing seat, bearing seat with flange, outer spherical bearing seat, etc., but in most cases, the bearing seat The use of bearings often has problems such as non-removable equipment, difficult lubrication, and short service life. For this reason, it is necessary to improve the structural use of the bearing seat. Contents of the invention [0003] The purpose of the present invention is to provi...
