Background

A reduction gear is generally provided between the traction machine and the traction sheave of the elevator to reduce the rotational speed of the traction sheave while improving the torque of the traction sheave, so that the car has a large load capacity while stably lifting.

The general speed reducer comprises a box body, a plurality of gears, an input shaft and an output shaft, and can be divided into a gear reducer, a worm reducer and a planetary gear reducer, in order to reduce the abrasion of meshing between the gears, a lubricating oil cavity is formed in the box body, a certain amount of lubricating oil is arranged in the cavity, and a part of gears are immersed in a part of the lubricating oil, so that a lubricating effect is achieved.

In order to prevent leakage of lubricating oil, a general speed reducer body is provided with a sealing mechanism at the joint of two half-bodies and at the rotation position of an input shaft and an output shaft and the box body, wherein a skeleton oil seal ring is generally used for sealing between the rotation position of the input shaft and the output shaft and the box body, but along with rotation of the shaft, the outside rubber of the skeleton oil seal is aged, and the pressure in the box body is changed, so that the lubricating oil in the box body can permeate from the inner section of the box body of the shaft to the outer section of the shaft, thereby forming leakage of the lubricating oil.

The lubricating oil that leaks can flow down to the frame of installation box along the lateral wall of box gradually to stretch into in the bolt on the frame thereupon, again because of elevator operation can produce vibrations, lead to the bolt on the frame to take place not hard up, influence the security of elevator, need often clear up the lubricating oil that leaks to the frame, increased maintenance cost.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides an anti-leakage speed reducer box body, which avoids oil seepage and dip dyeing of a base bolt, prolongs the maintenance period and reduces the maintenance cost.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides an antiseep speed reducer box, be provided with a plurality of axles that are used for input and output on the box, be provided with the oil groove that connects of corresponding axle on the lateral surface of box, connect the below that the oil groove is located the axle, a plurality of connect to be provided with the spread groove between the oil groove, connect each oil groove through the spread groove intercommunication, one of them connect the side of oil groove to be provided with the oil drain hole, be provided with detachable plug on the oil drain hole.

Further, the bottom surface of the oil receiving groove is inclined, and the oil drain hole is positioned on the side surface of the bottommost part of the oil receiving groove.

Further, an oil absorption sheet is arranged between the oil receiving groove and the shaft, and the oil absorption sheet is detachably connected with the box body.

Further, an elastic pressing sheet is arranged on the box body, and the oil absorption sheet is positioned between the elastic pressing sheet and the box body.

Further, the oil receiving groove is integrated with the box body.

Compared with the prior art, the utility model has the beneficial effects that: through setting up oil absorption piece and oil receiving groove in the below of the external corresponding axle of speed reducer case, when lubricating oil oozes from the inside through the axle rotation department of box, the lubricating liquid that flows down along the box lateral wall is absorbed to the accessible oil absorption piece earlier, and the rethread receives unnecessary lubricating liquid to avoid lubricating oil to dip the bolt on the frame, can temporarily store lubricating oil through receiving groove simultaneously, the maintenance clearance cycle of the lubricating liquid of extension oozing reduces maintenance cost.
