Anti-vibration device of vertical thrust sliding bearing

Abstract

The invention discloses an anti-vibration device of a vertical thrust sliding bearing. A bearing structure comprises a shell, a guide seat, a cooler and an anti-vibration device body, the shell is arranged outside the guide seat and the anti-vibration device body in a surrounding mode, an oil tank is formed by the shell in a surrounding mode, the anti-vibration device body is provided with an installation spigot and an oil passing hole, and a buffer part is arranged at the contact position of the anti-vibration device body and the guide seat; and the anti-vibration device body is installed between the guide seat and the shell and divides the oil tank into an upper layer and a lower layer, and the cooler is located on the oil tank on the lower layer. According to the anti-vibration device of the vertical thrust sliding bearing, damping and additional radial supporting are provided for the radial load of the bearing, when vibration impact exists, it is guaranteed that the radial rigidityof the bearing is sufficient, displacement deformation is small, and safe operation of the bearing is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of bearing structures, and in particular relates to an anti-seismic device of a vertical thrust sliding bearing. Background technique [0002] When mechanical equipment uses dynamic pressure sliding bearings, there will be shafting and equipment body vibrations in actual operation due to small oil film stiffness or large calculation errors. The increasing application requirements of various industries have also raised the vibration and noise of mechanical equipment. Increasingly stringent low noise requirements. Adding a damping structure between the back of the bearing and the bearing seat can effectively reduce the vibration and noise of mechanical equipment and solve the problem of low noise requirements of mechanical equipment. [0003] At present, the supporting part of the radial bearing of the integral vertical sliding bearing of the SM structure is a cylindrical guide seat structure. The guide seat ...

AI Technical Summary

Problems solved by technology

Therefore, under the impact load, the instantaneous rigidity is not enough, the structural damping is small, the displacement deformation is large, the impact load cannot be absorbed, and the overall radial stiffness of the shafting is affected.

[0004] Most of the cooled oil tank of the cooler is the outer lubricating oil. The bearing oil chamber has no specific oil circuit planning. The bearing lubricating oil circuit is open, and the hot and cold oil are freely mixed. Only part of the hot oil is cooled by the cooler, and the heat transfer efficiency is low. Low, the size of the cooler and bearing oil tank needs to be designed very large
