[0002] In the electric lifting table structure, the motor gear box is the core transmission component, responsible for converting the high-speed low-torque output of the motor into low-speed high-torque power suitable for the use of the lifting table. The structure of the gear directly affects the noise, smoothness, carrying capacity and life of the lifting table.

[0003] The maximum reduction ratio of the lifting table motor gear box gear currently in use is 1:39. When outputting the same torque, the input torque needs to be larger, and a worm gear is usually used for easy meshing with the worm, which is more cumbersome in the processing process, resulting in higher overall cost. Therefore, a novel gear for lifting table motor gear box is proposed. SUMMARY

[0004] The utility model discloses a novel gear for lifting table motor gear box to solve the shortcomings in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A novel gear for lifting table motor gear box, comprising a toothed disc, an outer gear ring is provided on the outer side of the toothed disc, an outer gear is formed on the outer gear ring, a center support block is installed at the center position of the toothed disc, an outer ring piece is provided on the outer side of the center support block, a center through hole is formed on the center support block, and an outer ring through groove is formed on the outer side of the center through hole.

[0007] Preferably, the outer gear ring is arranged in an annular shape on the annular surface of the outer gear ring, and forty-nine outer gears are arranged in an annular shape.

[0008] Preferably, the two sides of the toothed disc are symmetrically provided with center support blocks.

[0009] Preferably, the center through hole is horizontally formed between the two center support blocks, and the center through hole is a hexagonal through groove.

[0010] Preferably, the outer ring through groove is formed in multiple, and is arranged in an annular shape on the outer side of the center through hole. The outer ring through groove is also formed between the two center support blocks.

[0011] The utility model has the advantages of:

[0012] The present scheme can reduce the input torque by a ratio of one to forty-nine, the external teeth on the gear disc are helical, the machining operation is more convenient, the overall gear is an injection molding part, the cost is low, and the maintenance cost in the later period is reduced.

[0013] The present scheme reduces the input torque required during gear rotation, reduces the cost of gear manufacturing, improves the machining effect of the gear, and improves the possibility of cheaper gear replacement. BRIEF DESCRIPTION OF DRAWINGS
