Gearbox sealing mechanism

Abstract

The invention discloses a gearbox sealing mechanism, including a bearing installing seat which is provided with an installing hole, wherein a gear shaft is arranged in the installing hole in a penetrating manner, a transparent cover is arranged on the outer side of the gear shaft in a sleeving manner and fixed on the bearing installing seat, a bearing is arranged between the gear shaft and the bearing installing seat and positioned in the installing hole, an adjusting ring is arranged between the bearing and the transparent cover and arranged on the outer side of the gear shaft in a sleeving manner and positioned in the installing hole, the transparent cover is provided with an oil hole communicating with the installing hole, and an oil cup is installed in the oil hole. The gearbox sealing mechanism adopts grease with high viscosity for sealing, thus being unlikely to leak, and a cylindrical pin is assembled between the transparent cover and the adjusting ring, thus ensuring the smoothness of a return oil path. Two oil seals are also designed at the output end, thus further ensuring that gear oil is not leaked; long-time effective operation can be provided, meanwhile the oil cup is designed on the transparent cover, thus being capable of supplementing grease periodically, and preventing from wearing by lubricating oil seal.

Description

technical field [0001] The present application belongs to the technical field of gear boxes, and in particular relates to a sealing mechanism of a gear box. Background technique [0002] At present, the high-speed gearboxes used by users have a relatively fast speed, and most of them are sealed with oil seals. Only oil seals are used for sealing. , The losses caused by downtime, disassembly and maintenance cannot be estimated. [0003] Due to the high speed of the high-speed gearbox, a large amount of gear oil is required for the lubrication of the bearings. If the oil is not returned in time and the oil seal material is worn, oil leakage will occur. Contents of the invention [0004] The purpose of the present invention is to provide a gearbox sealing mechanism to overcome the deficiencies in the prior art. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006] The embodiment of the present application discloses...
