Abstract
The invention relates to an oil leakage preventing worm gear and worm speed reducer which comprises a casing, a worm gear, a worm and an output shaft. Lubricating oil is contained in the casing, two ends of the output shaft are vertically supported in the casing through bearings, an oil seal is respectively arranged on the outer sides of the bearings, the worm gear is fixedly connected to the output shaft in series and partially soaked into the lubricating oil, the worm penetrates into the casing in a connecting mode and is meshed with the worm gear, an oil blocking disc is connected onto the output shaft in a sleeved mode, the head portion of the oil blocking disc is connected with the bottom of the worm gear through a seal ring, and the bottom of the oil blocking disc is fixedly connected with the bottom of the casing. The barrel-shaped oil blocking disc is arranged between the bottom of the worm gear and the bottom of the casing, the upper portion of the oil blocking disc is sealed to the worm gear through the O-shaped seal ring, and the bottom of the oil blocking disc is in sealing connection with the bottom of the casing to enable the bearings and the lubricating oil to separated and prevent the lubricating oil from being leaked from the bearing positions. The oil leakage preventing worm gear and worm speed reducer is simple and effective in structure.
Description
Technical field
The present invention is specifically related to a kind of oil-leakage-prevention worm-gear speed reducer.
Background technique
In the housing of worm-gear speed reducer, be conventionally all marked with lubricant oil, worm gear and worm screw partial wetting are in lubricant oil, and lubricant oil is lubricated to reduce wear to worm gear, worm screw.Overflow at lubricant oil The book of Changes bearing place in practical work process middle shell, has both polluted speed reducer, can overflow the wearing and tearing that cause worm and gear because of lubricant oil again.In prior art, have the scheme that increases oil baffle disc below worm gear, but lubricant oil still can overflow from the matching gap of oil baffle disc and axle or worm gear, can not stop oil leakage phenomenon completely.
Summary of the invention
For overcoming deficiency of the prior art, object of the present invention with the worm-gear speed reducer that a kind of oil-leakage-prevention is provided.
For reaching above object, the technological scheme that the present invention takes is:
A kind of oil-leakage-prevention worm-gear speed reducer, comprise housing, worm gear, worm screw and output shaft, in described housing, lubricant oil is housed, the two ends of described output shaft are supported on housing through the vertical shape of bearing, the outside of described bearing is respectively equipped with oil sealing, described worm gear is fixedly serially connected with output shaft partial wetting in lubricant oil, described worm screw is connected in housing and engages with worm gear, on described output shaft, be socketed with oil baffle disc, described oil baffle disc head is connected with worm gear bottom through seal ring, and described oil baffle disc bottom is fixedly connected with housing bottom.
Further, described worm gear bottom is provided with the annular groove coaxial with output shaft, and described oil baffle disc is tubular, and the head of oil baffle disc is socketed with O RunddichtringO, the inner crush seal of described O RunddichtringO and annular groove, is provided with Sealing between described oil baffle disc bottom and housing bottom surface.
Again further, the head of described oil baffle disc exceeds the liquid level of lubricant oil.
Take after above technological scheme, beneficial effect of the present invention is:
Between worm gear bottom and housing bottom, be provided with the oil baffle disc of tubular, oil baffle disc top is through O RunddichtringO and worm gear sealing, and oil baffle disc bottom is tightly connected with housing bottom, and Bearing and lubrication oil is intercepted and opened, place lubricant oil and spill from bearing place, simple in structure, effective.
