Gearbox body

Abstract

The invention discloses a gearbox body, which comprises an upper box body and a lower box body. The upper box body and the lower box body are connected in a fastened mode through bolts, an viewing maintenance window is arranged on the upper end face of the upper box body, a cover body covers a window opening of the viewing maintenance window, the viewing maintenance window is in a rectangle shape,blocking bars are arranged on the inner wall, around the viewing maintenance window, of the upper box body, and the height of the blocking bars is 3-5 cm; platform-like upper connecting edges are arranged on the two sides of the upper box body, platform-like lower connecting edges are arranged on the two sides of the lower box body, conical sealing teeth are arranged on the upper connecting edges, and conical grooves adapted to the conical sealing teeth are formed in the lower connecting edges. According to the gearbox body, splashing lubricating oil can be prevented from hitting the cover body of the maintenance window through the blocking bars, and the condition that the cover body is covered with the lubricating oil and consequently the interior of the box body cannot be viewed is avoided; and the conical sealing teeth and the conical grooves are matched, the sealing effect is ensured, and the positioning effect can further be ensured.

Description

[0001] Technical field: [0002] The invention relates to a gearbox case. [0003] Background technique: [0004] The gears in the existing reduction box are lubricated by an oil bath, the gears are lubricated by dipping oil in the oil pool, and the bearings are lubricated by splashing, which is characterized by a large load and is suitable for long-term operation. When the gear rotates, the lubricating oil is thrown out, and the splashed lubricating oil hits the inspection window, which affects the observation clarity of the inspection window. In addition, the sealing performance of the joint of the upper and lower casings in the existing gearbox is difficult to ensure, and the sealing effect of the junction of the upper and lower casings is difficult to guarantee. [0005] Invention content: [0006] The present invention provides a gearbox case in order to solve the above-mentioned problems in the prior art. [0007] The technical solutions adopted in the present inventio...
