Description

Technical Field

[0001] The utility model belongs to the technical field related to mechanical manufacturing, and particularly relates to a high-sealing worm gear box end cover. Background Technique

[0002] A worm gear box generally refers to a speed reduction device equipped with a worm gear and a worm. It reduces the rotational speed of the input shaft and increases the torque of the output shaft through the meshing of the worm gear and the worm. Worm gear boxes are widely used in various mechanical equipment for speed reduction transmission, such as in the fields of industrial automation, transportation tools, construction machinery, etc.

[0003] The end cover of the worm gear box is a component of the worm gear and worm reducer. Its main function is to fix the axial position of the shafting components and bear the axial load. The end covers of the worm gear box are usually located at both ends of the reducer, cooperate with the box body, and are fixed by bolts to ensure the structural integrity and normal operation of the entire reducer. In some designs, the end cover may also include elements for sealing to prevent lubricating oil leakage or external contaminants from entering the interior of the reducer.

[0004] Since the worm gear reducer transmits power through the sliding friction between the worm gear and the worm, this friction generates heat. The end cover, as a component of the reducer, is usually used to enclose the bearing seat hole, fix the axial position and bear the axial load. During the operation of the worm gear reducer, the bearings and other transmission components near the end cover may heat up due to friction. If the heat dissipation is poor, the temperature of these components may rise, thereby affecting the normal operation and service life of the entire reducer.

[0005] The utility model improves the above problems and particularly relates to a high-sealing worm gear box end cover that can accelerate heat dissipation. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a high-sealing worm gear box end cover to solve the problem that during the operation of the worm gear reducer, the bearings and other transmission components near the end cover may heat up due to friction.
