Description

Technical Field

[0001] The utility model relates to the field of gears, in particular to a small gear that can be disassembled and replaced. Background Art

[0002] Pinion gears are widely used in the field of mechanical transmission as a transmission component. Due to their wide application range and large number of uses, pinion gears are required to have good installation and positioning performance and high transmission efficiency. At present, pinion gears are widely used in various mechanical equipment and can be seen everywhere on various production lines. After searching, a pinion gear disclosed in the application number CN201922389886.4 is recorded to include a ring and a connecting disk. The ring is used to position the gear seat and the transmission seat on the outside to ensure the overall stability and avoid the impact of external objects on the operation of the gear. The connecting shaft is installed in the connecting disk, and the side plate covers the connecting shaft from the outside to make the overall connection position tighter. At the same time, it can also protect the connecting shaft. However, the above description still has the following defects in actual use: the existing pinion gear needs to replace the entire tooth teeth when in use, which increases the cost. At the same time, the surface of the tooth teeth lacks a wear-resistant protective structure, which makes the overall gear not durable. Therefore, it is necessary to design a practical and removable pinion gear. Utility Model Content
