Problems solved by technology
The current static pressure support system generally adopts a fan-shaped plane structure. When the applied load is unevenly distributed, especially when the partial load is serious, it is easy to cause the temperature of the support system to be too high, or even burn out.
In addition, the existing device for supplying oil to the static pressure support system only simply distributes the flow, without compensating and adjusting the flow of each oil supply port. The stable oil supply makes the static pressure support system unable to form a stable working oil film, which affects the normal operation of the reducer

Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing.
[0015] Depend on figure 1 As shown, the cylindrical spherical surface pressure bearing system of the present invention includes 12-16 independent spherical surface pressure bearings, wherein every 4 to 8 independent spherical surface pressure bearings form a group, figure 1 There are 16 of them, and every 4 spherical hydrostatic bearings form a group, and the spherical hydrostatic bearings in each group share a high-pressure valve block 6, and each spherical hydrostatic bearing connects with the high-pressure valve block 6 through its own independent oil passage. connected, the oil passage is also provided with a one-way valve 7, and each set of spherical hydrostatic bearings is evenly distributed on the same annular plane in a staggered order; see image 3 , one path of high-pressure oil (I) enters the high-pressure valve block 6 and is divided into 4 paths for oil supply...

The invention discloses an adaptive variable working condition cylindrical spherical pressure bearing system. The system comprises 12 to 16 independent spherical hydrostatic bearings, wherein every 4 to 8 independent spherical hydrostatic bearings form a group; the spherical hydrostatic bearings in each group share a high-pressure valve block; each spherical hydrostatic bearing is connected with the high-pressure valve blocks through own independent oil passages; each oil passage is also provided with a one-way valve; and each group of spherical hydrostatic bearings are uniformly distributed on the same circular plane in a sequential staggering way. The system can automatically swing to perform adjustment along with the change of the action direction of a load, also prevent the change of an oil supply flow along with pressure or temperature fluctuation and ensure stable oil supply to ensure that a stable working oil film is formed.
Description
technical field [0001] The invention relates to a cylindrical spherical pressure bearing system used in a large vertical roller mill reducer. Background technique [0002] The static pressure support system is one of the most important components in the large vertical roller mill reducer. It needs to bear the weight of the mill and the grinding force during the grinding process. Its working performance is directly related to the safe and reliable operation of the reducer. The current static pressure support system generally adopts a fan-shaped plane structure. When the applied load distribution is uneven, especially when the partial load is serious, it is easy to cause the temperature of the support system to be high, or even burn out. In addition, the existing device for supplying oil to the static pressure support system only simply distributes the flow, without compensating and adjusting the flow of each oil supply port. The stable oil supply makes the static pressure su...
