Vertical thrust sliding bearing anti-shock device

Abstract

The invention discloses a vertical thrust sliding bearing anti-shock device. A bearing structure comprises a shell, a guide seat, a cooler and the anti-shock device. The shell is arranged outside theguide seat and the anti-shock device in an enclosing mode. The shell defines a space to form an oil tank. The anti-shock device is provided with a mounting rabbet and oil holes. A buffer part is arranged in the position, making contact with the guide seat, of the anti-shock device. The anti-shock device is mounted between the guide seat and the shell. The anti-shock device divides the oil tank into an upper layer and a lower layer. The cooler is located on the lower layer of the oil tank. The vertical thrust sliding bearing anti-shock device provides damping and additional radial supporting for a radial load of a bearing and ensures sufficient radial stiffness, small displacement deformation and safe operation of the bearing in case of vibration and shock.

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 ...

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
