Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

Example (b): sealed integral type bearing frame

Including fixing base 1, fixing base 1 is round platform shape, and generating line inclination is 7, the bottom of fixing base 1 is equipped with rather than integrative injection moulding's encapsulation board 2. The thickness of the package plate 2 is 15mm, the package plate 2 is square in the example, the central line of the package plate 2 is flush with the axis of the fixed seat 1, and the package plate and the fixed seat are arranged in the middle relatively. The packaging plate 2 is provided with a rib plate with the thickness of 5mm, the packaging plate 2 is provided with a hole matched with the bolt and used for installing and fixing the packaging plate 2, and the hole is formed in the edge of the rib plate.

For the cooperation machine tool, be equipped with circular shape boss 3 on the bottom installation face of encapsulation board 2, boss 3 is coaxial with

mounting hole

5, 3 external diameter 108mm of boss, protrusion 4mm with the cooperation of the 108 frock holes on the machine tool, can effectively prevent to be the bearing frame offset that vibrations lead to because of the machine operation, improve the machining precision, reduce the processing degree of difficulty.

The fixing base 1 is gone up along its axial and is equipped with pilot hole 4 that link up between two parties, pilot hole 4 is used for installing the insert bearing, pilot hole 4 is the inner wall and insert bearing standard component matched with spherical curved surface.

The packaging plate 2 is provided with a mounting hole 5 which is coaxially communicated with the assembly hole 4 in a penetrating manner in the middle, an oil seal groove 7 is formed in the bottom edge of the mounting hole 5, the diameter of the oil seal groove 7 is 75mm (plus or minus 0.02mm), 35 x 75 x 12 oil seals 6 are installed in the oil seal groove, dust and splashed water are prevented from directly contacting the bearing to influence the service life of the bearing, the structure and the oil seals 6 and a bearing seat form an integral product structure, the assembly hole 4, the mounting hole 5 and the oil seal groove 7 are processed in a one-step forming mode, the concentricity is high, the inner ring of the bearing can be guaranteed to be coaxial with the inner ring of the oil seal 6 after the bearing is assembled, and the problems that the tolerance fit caused by the fact that the plastic plate is externally arranged in the assembly of the existing bearing is poor, the shaft and the bearing are not concentric.

The technology groove of current spherical bearing seat generally sets up in the below of bearing frame originally in this design the top annular end face of pilot hole goes up the symmetry and sets up technology groove 8 for the installation with dismantle inside complex spherical bearing, let dismouting complex structure expose externally, keep away from the installation face, made things convenient for the dismantlement of bearing installation and maintenance.

The existing bearing seat and the bearing with the bearing seat have the common thickness of about 20mm, the end face of the outer end of the bearing seat is also of an exposed structure, and after the bearing seat meets water and runs dust, water and sewage are accumulated, and a fastening screw is rusted on a shaft when the bearing is replaced. This bearing frame is still including the leather cup end cover 9 of independent setting, leather cup end cover 9 uses nitrile rubber for the rubber spare, and flexible deformable, and has certain extensibility can, through cup jointing, and the outside of fixing base 1 rises to jam in leather cup end cover 9, lets outside exposure part more pleasing to the eye, and the important can protect inside the bearing, waterproof dustproof, improvement bearing's life. In order to match with the special assembly leather cup end cover 9 of the design, the fixing part is extended outwards by 4-6mm to form an extension part, so that the overall height of the fixing part is 26mm, and the leather cup end cover 9 can be conveniently buckled on the outside.

The bearing seat is usually installed and used for the horizontal arrangement of the axis when in use, although the problem of water inflow is basically eliminated through the arrangement, in case of prevention, a water drainage hole 10 is arranged at the root part (the edge connected with the packaging plate 2) of the fixed seat 1, and the inner end opening of the water drainage hole 10 is positioned in the space between the installed spherical outside surface bearing and the oil seal 6, so that in case of water leakage of the oil seal 6 can be prevented, accumulated water can be effectively drained, the bearing seat can be cleaned in time, and long-term corrosion of the bearing caused by water can be reduced. The drain hole 10 is provided with a sealing plug for controlling the opening and closing of the hole.

The middle part of the assembly hole 4 is provided with an oil filling groove 11 along the circumferential direction thereof.

The bearing seat mainly comprises two independently arranged components. Wherein fixing base 1 and encapsulation board 2 are all whole injection moulding, and its inside and the plane of bottom surface are the later stage processing, and this method precision is very guaranteed, compares current bearing frame, and the installation is used still to cooperate other subassembly to see, has improved greatly in the aligning setting of bearing, has realized fine maintenance, extension bearing's application precision and life to the maintenance and the operating condition of bearing.

The leather cup end cover 9 and the drain hole 10 are arranged, so that the overall waterproof effect is further improved, and the damage of the soaking operation to the bearing is greatly reduced.
