The utility model discloses an automobile steering gear installation bushing stripping force detection tool comprising a pressure head, a guide column, a guide block and a pedestal, the pedestal is internally provided with a through hole extending up and down, the upper part of the through hole is provided with a circle of sinking platform, the guide block is supported on the sinking platform and is limited in the through hole in the circumferential direction, and the guide block is provided with a through hole extending up and down. The guide column comprises an upper section and a lower section, the upper section and the lower section are in step transition, the diameter of the lower section is matched with the hole diameter of the through hole, the diameter of the upper section is smaller than that of the lower section, the upper section is matched with the inner diameter of the installation lining base body, the upper section is sleeved with the installation lining base body, and the outer diameter of the installation lining base body is consistent with the diameter of the lower section. The bottom face of the pressing head abuts against the top face of the installation lining base body and the top face of the installation lining rubber. The stripping force detection tool for the mounting bushing overcomes the defects of the existing stripping force detection tool for the mounting bushing, improves the accuracy and reliability of detection, and ensures the quality and performance of the mounting bushing.

This invention provides a screw drill bit, including a rotor, a stator housing, and a rubber bushing. The rubber bushing is disposed within the stator housing and has a first mounting hole along its axial direction. The rotor is disposed within the mounting hole and forms a conjugate sealing cavity with the mounting hole. The conjugate sealing cavity is connected to drilling fluid. The rotor has a first through hole along its axial direction and multiple second through holes spaced apart along its radial direction. The second through holes connect the first through holes to the conjugate sealing cavity, and the first through holes are connected to lubricant. By providing the first through holes on the rotor, which are connected to the lubricant, the drilling fluid enters the conjugate sealing cavity and drives the rotor to rotate. During the rotor's rotation, the lubricant enters the conjugate sealing cavity from the first through holes through the second through holes, achieving lubrication and drag reduction for the rotor and the rubber bushing. The screw drill bit of this embodiment has a simple structure and improves the service life of the rotor and the rubber bushing.

This utility model discloses a bass bearing with noise reduction function, including a hollow corrugated shell, an outer ring fixedly installed inside the hollow corrugated shell, and an inner ring rotatably installed inside the outer ring. Both ends of the inner ring surface are fixed with cages, and several equally spaced balls are embedded inside the cages, contacting the inner wall surface of the outer ring. A rubber bushing is fixed to the inner wall of the inner ring, and a fan-shaped protrusion is integrally formed on the outer wall of the rubber bushing. The end of the fan-shaped protrusion extends outward and penetrates to the outside of the inner ring. This utility model, through the interlocking structure of the inner ring, rubber bushing, fan-shaped protrusion, and cage, allows the inner ring to roll and rub against the outer ring via the cage and balls. During this rolling friction, the rubber bushing in the inner ring continuously contacts the double-wing elastic oil overflow structure via the fan-shaped protrusion, causing grease from the polyurethane foam block to overflow.

The invention provides a sealing bush for an air spring and the air spring, relates to the technical field of air springs, and aims to solve the technical problem that a linear motor type shock absorber cannot be mounted on the air spring in the prior art. A sealing bush for an air spring comprises a bush framework, a bush sizing material, a bush inner core and a shell, the bush framework is provided with a first through hole in the axial direction, and the bush framework comprises a connecting part used for being connected with a bag skin; the lining rubber material is connected into the first through hole, and a second through hole is formed in the lining rubber material in the axial direction; the lining inner core is connected into the second through hole, and a third through hole is formed in the lining inner core in the axial direction; the shell is connected into the third through hole, a mounting cavity for mounting the motor and the cooling device is formed in the shell, and the mounting cavity penetrates through the lower end face of the shell and forms an opening in the upper end face of the shell; the invention further relates to the air spring which comprises the sealing bush for the air spring, a piston and a bag skin, the upper end of the bag skin is connected with a connecting part, and the lower end of the bag skin is connected with the piston.

The utility model relates to a lining inner core structure which comprises a lining inner core, lining rubber, a lining outer pipe and a performance debugging block. The lining inner core is cylindrical, the lining rubber is arranged on the outer side of the lining inner core in a sleeving mode, and the lining outer pipe is arranged on the outer side of the lining rubber. A performance debugging block is arranged between the lining inner core and the lining rubber; according to the utility model, on the basis of a similar structure, the internal structure of the bushing is changed, and the scheme effect of a multi-scheme product can be quickly verified, so that the loading performance requirement is met.

The utility model relates to a large-swing-angle lining structure which comprises a lining shell, lining rubber and a lining inner pipe. The outer side of the lining inner pipe is sleeved with lining rubber, and the outer side of the lining rubber is sleeved with a lining shell. The bushing shell comprises a first bushing and a second bushing, the outer edge of the first bushing is provided with a first bushing horn mouth, and the outer edge of the second bushing is provided with a second bushing horn mouth; according to the large-swing-angle lining structure, the swing angle space of the lining inner pipe can be adjusted by adjusting the angle and the length of the horn mouth of the lining shell, the first lining structure and the second lining structure are adjusted respectively, the requirements of different road conditions are met, and therefore the large-swing-angle lining structure is suitable for verification of different schemes at the same time, economical, practical and low in cost.
