Description

Technical Field

[0001] The utility model relates to the technical field of revolving supports of elevators, and particularly relates to a single-row revolving support structure for elevators. Background Technique

[0002] Revolving supports are widely used in the real industry and are known as "the joints of machines". They are important transmission components necessary for machinery that needs to make relative revolving movements between two objects and simultaneously bear axial forces, radial forces, and tipping moments. Revolving supports can be divided into single-row revolving supports, double-row revolving supports, and three-row roller-type revolving supports, etc. The revolving support used for the work of an elevator is usually a single-row revolving support structure.

[0003] The existing single-row revolving support structure usually consists of spacer blocks, balls, an outer ring, and an inner ring. The part of the elevator used for operation is installed on the outer ring. Through the cooperation of the spacer blocks and the balls, the outer ring and the inner ring rotate, so as to realize the rotation of the part of the elevator used for operation. To ensure the use effect of the single-row revolving support structure, lubricating oil is usually added to the revolving support. The lubricating oil accumulates in the gaps between the spacer blocks and the balls, and the waste oil after use will still accumulate in the gaps between the spacer blocks and the balls. The accumulated waste oil may affect the use effect of the new oil and may reduce the use effect of the spacer blocks and the balls. Therefore, a single-row revolving support structure for elevators is proposed to solve the above problems. Summary of the Invention

[0022] Please refer to Figure 1-2 , the present utility model provides a technical solution:

[0023] A single-row slewing bearing structure for a lift, comprising an outer ring 1, an inner ring 2, spacer blocks 3 and balls 4. An upper sealing ring 5 is snap-fitted to the inner side of the outer ring 1. A plurality of first damping balls 6 of equal size are fixedly connected to the outer side of the upper sealing ring 5. An annular oil storage pipe 7 is arranged on the inner side of the upper sealing ring 5. An oil inlet pipe 8 is communicated with the inner side of the annular oil storage pipe 7. Eight oil outlet pipes 11 of equal pipe diameter are communicated with the bottom of the annular oil storage pipe 7. An oil waste box 13 is fixedly connected to the bottom of the inner ring 2. Eight oil leakage pipes 12 of equal pipe diameter are communicated with the top of the oil waste box 13. A lower sealing ring 14 is sleeved on the outer side of the oil waste box 13. A plurality of second damping balls 15 are fixedly connected to the outer side of the lower sealing ring 14. An oil discharge pipe 16 is connected to the inner side of the oil waste box 13. Eight first leakage holes 9 of equal hole diameter are opened on the inner side of the inner ring 2. Eight second leakage holes 10 of equal hole diameter are opened on the inner side of the inner ring 2.

[0024] The inner ring 2 is arranged between the annular oil storage pipe 7 and the waste oil box 13. The annular oil storage pipe 7 is fixedly connected to the inner ring 2. This arrangement enables the positioning of the annular oil storage pipe 7 and the waste oil box 13. The oil outlet pipe 11 is arranged in one-to-one correspondence with the first leakage hole 9, and the oil leakage pipe 12 is arranged in one-to-one correspondence with the second leakage hole 10. This arrangement enables the oil outlet pipe 11 to be installed inside the inner ring 2 through the first leakage hole 9, and the oil leakage pipe 12 to be installed inside the inner ring 2 through the second leakage hole 10. A number of first damping balls 6 are arranged in an equiangular array with the same center, and a number of second damping balls 15 are arranged in an equiangular array with the same center. This arrangement enables the second damping balls 15 to increase the contact area between the lower sealing ring 14 and the outer ring 1, increase the friction between the lower sealing ring 14 and the outer ring 1, so that the lower sealing ring 14 can be stably placed outside the outer ring 1. The first damping balls 6 increase the contact area between the upper sealing ring 5 and the outer ring 1, increase the friction between the upper sealing ring 5 and the outer ring 1, so that the upper sealing ring 5 can be stably placed outside the outer ring 1. The outer ring 1 is sleeved outside the inner ring 2. The isolation block 3 and the rolling balls 4 are both arranged between the outer ring 1 and the inner ring 2. This arrangement enables the positioning of the single-row slewing bearing.

[0025] Working process: Install the part of the lift used for operation on the outer ring 1. Through the cooperation of the isolation block 3 and the rolling balls 4, the outer ring 1 and the inner ring 2 rotate, so as to realize the rotation of the part of the lift used for operation. Before the lift is put into use, lubricating oil is added to the annular oil storage pipe 7 through the oil inlet pipe 8. The lubricating oil flows out of the annular oil storage pipe 7 through the oil outlet pipe 11. The oil outlet pipe 11 is installed inside the inner ring 2 through the first leakage hole 9. The flowing lubricating oil acts on the isolation block 3 and the rolling balls 4 and lubricates them. The used lubricating oil flows into the waste oil box 13 through the oil leakage pipe 12. The oil leakage pipe 12 is installed inside the inner ring 2 through the second leakage hole 10. The waste lubricating oil is collected by the waste oil box 13 and then discharged through the drain pipe 16, reducing the occurrence of the situation that the lubricating oil accumulates in the gaps between the isolation block 3 and the rolling balls 4 and affects their use effect. The upper sealing ring 5 and the lower sealing ring 14 respectively corresponding to the top and bottom of the inner ring 2 can enhance the sealing performance between the outer ring 1 and the inner ring 2, reducing the occurrence of dust entering the inner ring 2. The first damping balls 6 increase the contact area between the upper sealing ring 5 and the outer ring 1, increase the friction between the upper sealing ring 5 and the outer ring 1, so that the upper sealing ring 5 can be stably placed inside the outer ring 1. The second damping balls 15 increase the contact area between the lower sealing ring 14 and the outer ring 1, increase the friction between the lower sealing ring 14 and the outer ring 1, so that the lower sealing ring 14 can be stably placed inside the outer ring 1.

[0026] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
