Abstract
The utility model relates to 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.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.
Description
Technical field
The utility model relates to a kind of speed reducer, 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, the purpose of this utility model with the worm-gear speed reducer that a kind of oil-leakage-prevention is provided.
For reaching above object, the technological scheme that the utility model is taked 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, the beneficial effects of the utility model are:
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.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: housing 1, lubricant oil 2, worm screw 3, worm gear 4, output shaft 5, oil baffle disc 6, oil sealing 7, O RunddichtringO 8, circular groove 9.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described:
A kind of oil-leakage-prevention worm-gear speed reducer, comprises housing 1, lubricant oil 2, worm screw 3, worm gear 4, output shaft 5, oil baffle disc 6, oil sealing 7 and O RunddichtringO 8.In described housing 1, be marked with lubricant oil 2, described output shaft 5 is vertical shape through bearing and is supported on housing 1, and bearing outside is provided with the oil sealing 7 that forms sealing with housing; Described worm gear 4 is fixedly serially connected with output shaft 5, described worm screw 3 is serially connected with housing and engages with worm gear 4, described worm gear bottom is provided with the circular groove 9 coaxial with output shaft 5, described oil baffle disc 6 is straight-tube shape, described oil baffle disc 6 heads are socketed with O RunddichtringO 8, and described oil baffle disc 6 heads stretch in circular groove 9, O RunddichtringO 8 and circular groove 9 inwall crush seals, described oil baffle disc 6 bottoms are fixedly connected with housing 1 bottom through screw, between oil baffle disc 6 bottoms and housing 1 bottom, are provided with seal ring.
