Embodiment 1

[0031] Figure 1 to Figure 3 It shows the first embodiment of the anti-seismic device of the vertical thrust sliding bearing of the present invention. The bearing structure includes a shell, a guide seat, a cooler, a guide shoe, a thrust head and an anti-seismic device. Outside the tile, cooler, thrust head and anti-seismic device, the shell is surrounded by an oil tank. The thrust head is set on the rotor, the guide seat is set outside the thrust head, the guide shoe is located between the thrust head and the guide seat, and the cooler is set outside the guide seat.

[0032] In this embodiment, the anti-seismic device is provided with a mounting stop and an oil hole, and a buffer part is provided at the contact between the anti-seismic device and the guide seat. , the cooler is located in the lower tank.

[0033] In this embodiment, the anti-seismic device includes an inner ring, an outer ring, and bolts. There are multiple bolts, which are evenly distributed along the circ...

Embodiment 2

[0041] Figure 4 to Figure 6 The second embodiment of the anti-seismic device of the vertical thrust sliding bearing of the present invention is shown. The difference between this embodiment and Embodiment 1 is that the anti-seismic device is a circular anti-vibration plate, and there are multiple oil holes on the anti-vibration plate. The oil holes are distributed along the circumference, and the installation notches are arranged at the outer and inner circumferential ends of the anti-vibration plate. The anti-seismic plate is provided with a circular mounting hole, and the mounting hole is provided with multiple give way slots to ensure product installation and easy and compact disassembly.

[0042] In this embodiment, the anti-seismic plate is provided with an oil hole, and the hot oil part of the lubricating oil flows through the oil hole of the anti-vibration plate and then flows through the cooler to ensure that the cooler and the hot oil are fully contacted and exchange...

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 ...
