Abstract

The utility model belongs to the technical field of the bearing technique and specifically relates to a tilting pad slide bearing is related to, including bearing body, end cover, tilting pad, location throttle screw, fastening screw, tilting pad is packed into the bearing body inside from bearing body front end opening part, and the end cover passes through fastening screw to be fixed on the opening of bearing body front end, and location throttle screw connects tilting pad, and the bearing body hole adopts cambered surface structure, and the bearing body hole is circumference linear contact with the tilting pad back. The beneficial effects of the utility model reside in that: the bearing body inner hole adopts the cambered surface structure, and the bearing body inner hole is circumference linear contact with the tilting pad back, therefore, the pad can be along with the proper certain angle of beat of hole high point, in the use in practice, has certain self-aligning from the centering function, allows the certain axle of rotor to be not centering, and this design has avoided designing into spherical surface cooperation structure for the self-aligning from the centering function of designing the bearing with bearing structure is complicated.

Description

Tilting pad sliding bearing

Technical Field

The utility model belongs to the technical field of the bearing technique and specifically relates to a tilting pad slide bearing is related to.

Background

A tilting-pad multi-oil-wedge bearing is a bearing form with the best stability, a tilting pad block is generally formed by pouring Babbitt metal into 4, 5 or more inner holes, the inclination of the pad block can be adjusted in a white motion mode along with the change of load and speed, multi-oil wedges are formed around a shaft neck, a pad back arc of each pad block is in line contact with an inner hole of a bearing body, an oil film gap can be adjusted in a white motion mode during operation, and therefore the tilting-pad bearing has good vibration attenuation performance and is mainly applied to high-speed light-load equipment such as a steam turbine, a compressor, turbine equipment and a pump.

From the stability, the tilting pad bearing has better vibration suppression performance, but has higher installation requirement on unit equipment, and the conventional tilting pad bearing adopts the matching of the bearing and the spherical surface of the unit to achieve the self-aligning function, but the structure causes the defects of complex structure, higher precision requirement, complex process and the like.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a tilting pad slide bearing to solve the technical problem among the prior art.

The utility model provides a tilting pad slide bearing, including bearing body, end cover, tilting pad, location throttle screw, fastening screw, the tilting pad is packed into the bearing body inside from bearing body front end opening part, and the end cover passes through fastening screw to be fixed on the opening of bearing body front end, and location throttle screw connects the tilting pad, and the bearing body hole adopts cambered surface structure, and the bearing body hole is circumference linear contact with the tilting pad back.

The beneficial effects of the utility model reside in that: the bearing body inner hole adopts the cambered surface structure, and the bearing body inner hole is circumference linear contact with the tilting pad back, therefore, the pad can be along with the proper certain angle of beat of hole high point, in the use in practice, has certain self-aligning from the centering function, allows the certain axle of rotor to be not centering, and this design has avoided designing into spherical surface cooperation structure for the self-aligning from the centering function of designing the bearing with bearing structure is complicated.
