Technical Field

The invention relates to the technical field of screw compressor assembly, in particular to a bearing mounting device and a bearing mounting method.

Background

In the running process of the screw compressor, the cylindrical roller bearings at the two ends of the rotor enable the rotor to realize radial positioning, bear radial force in the running process of the compressor, reduce the friction torque of the rotor, enable the rotor to rotate flexibly, have certain supporting precision and ensure the rotation precision of the rotor.

The existing installation tool for the cylindrical roller bearing is heavy, cumbersome and non-guiding, an installation hole with the size slightly smaller than the outer diameter of the bearing is formed in a shell, the inner wall of the installation hole has certain taper, the diameter of the deep hole is smaller, the bearing can be clamped and fixed, the bearing is generally required to be knocked into the installation hole by means of a hammer in the installation process, the surface of the bearing is easily damaged, and the installation tool is not guided, so that when the bearing is inclined, the bearing outer wall and the inner wall of a positioning hole are easily damaged, and the product quality and the performance are affected.

Disclosure of Invention

In order to solve the problems that the existing bearing is difficult to mount, is easy to damage and reduces the quality and performance of a product, the invention provides a bearing mounting device which can conveniently and accurately mount a bearing in place, cannot damage and improve the quality and performance of the product, and meanwhile, the invention also provides a corresponding mounting method.

The technical scheme is as follows: the utility model provides a bearing installation device, its characterized in that, it includes the gland, gland one end be provided with bearing complex clamping ring, scribble the abrasionproof coating on the clamping ring, the clamping ring external diameter corresponds with the mounting hole internal diameter.

The device is further characterized in that the gland is in 8-degree taper connection with the short connection cylinder, the short connection cylinder is in threaded connection with the lengthened connection cylinder, and the other end of the lengthened connection cylinder is in threaded connection with the connection cylinder cover;

the short connecting cylinder, the lengthened connecting cylinder and the connecting cylinder cover are all sleeved with PVC plastic sleeves.

A bearing installation method is characterized in that a bearing is aligned to an installation hole, a pressing ring presses the bearing by using a pressing cover, the pressing cover is knocked to press the bearing into the installation hole, and after the bearing completely enters the rear installation hole, the pressing ring enters the installation hole and is matched with the inner wall of the installation hole to realize guiding so that the bearing is accurately installed in place.

The device is further characterized in that a short connecting cylinder is installed on the press cover in a 8-degree taper connection mode, the short connecting cylinder is connected with a lengthened connecting cylinder in a threaded mode, and the other end of the lengthened connecting cylinder is connected with a connecting cylinder cover in a threaded mode; and then the pressing ring presses the bearing for subsequent operation.

After the anti-abrasion bearing pressing ring is adopted, the anti-abrasion coating is coated on the pressing ring, the knocking part is arranged on the pressing cover or the cylinder connecting cover, so that the pressing ring can not scratch the contact surface of the bearing when the bearing is pressed in, and the outer diameter of the pressing ring corresponds to the inner diameter of the rotation mounting hole, so that a guiding effect can be achieved, the bearing can be accurately installed in place, damage can not occur, and the product quality and performance are improved.
