The front end of the worm is arranged inside the supporting cavity in the front end of the shell through a deep groove ball bearing, the rear end of the worm gear is arranged inside the supporting cavity in the rear end of the shell through two conical roller bearings, the two conical roller bearings are respectively arranged in an opposite mode, and the wall of the supporting cavity in the rear end of the shell is provided with axial limiting steps matched with the two conical roller bearings. The reinforced universal installation worm and gear reducer has the advantages of being large in whole bearing capacity, high in axial impact resistance, and convenient and flexible to use.
Description
Technical field
The utility model relates to the worm-gear speed reducer product technical field, and a kind of reinforced universal installation worm-gear speed reducer specifically is provided.
Background technique
At present, common worm-gear speed reducer, as shown in Figure 1, it comprises housing 101, worm screw 102 and worm gear 103 are installed in housing 101, and worm gear 103 forms reducing gears with worm screw 102 engagement driving, and housing 101 rear and front ends all have the supporting cavity, the two ends of worm screw 102 tapered roller bearing 104 respectively are arranged on described supporting cavity, and axially locating is realized by 105 pairs of tapered roller bearings 104 of jump ring in worm screw 102 rear ends.The axial impact ability that can bear due to jump ring 105 location is very little, and jump ring 105 easily damages, has then shortened the whole service life of bearing, the integrated carrying ability of reduction speed reducer.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of total bearing capacity is large, anti-axial impact ability is high, the reinforced universal installation worm-gear speed reducer of easy to use and flexible.
goal of the invention of the present utility model is achieved in that a kind of reinforced universal installation worm-gear speed reducer, it comprises housing, worm screw and worm gear are installed in housing, worm gear and worm meshing transmission form reducing gear, the housing rear and front end all has the supporting cavity, the two ends of worm screw are arranged on respectively on described supporting cavity, it is characterized in that: the front end of worm screw is arranged in the supporting cavity of housing front end by deep groove ball bearing, the rear end of worm screw is arranged in the supporting cavity of housing rear end by two tapered roller bearings, two tapered roller bearings are oppositely installed respectively, establish the axial limiting step that matches with two tapered roller bearings on the wall body of the supporting cavity of described housing rear end.
Reinforced universal installation worm-gear speed reducer described in the utility model, the front end of described worm screw is connected with input flange.
Furthermore, above-mentioned reinforced universal installation worm-gear speed reducer, described worm screw rear end is provided with tapered roller bearing is fixed on locking nut on worm screw.
Reinforced universal installation worm-gear speed reducer described in the utility model, it is equipped with expanding ring between described input flange and worm screw in any one above-mentioned technological scheme.
Preferably, above-mentioned reinforced universal installation worm-gear speed reducer is provided with oil sealing in the supporting cavity of described housing rear end.
The utility model is compared with worm-gear speed reducer of the prior art, has the following advantages:
Reinforced universal installation worm-gear speed reducer described in the utility model, the front end of worm screw is arranged in the supporting cavity of housing front end by deep groove ball bearing, the rear end of worm screw is arranged in the supporting cavity of housing rear end by two tapered roller bearings, two tapered roller bearings are oppositely installed respectively, two tapered roller bearings are arranged on housing by the axial limiting step, therefore the tapered roller bearing of worm screw rear end can bear larger axial impact force, effectively prevent damage of bearings, improved the axial carrying capacity of speed reducer.And, therefore the worm screw front end also can change the outfit into deep groove ball bearing, and when deep groove ball bearing is positioned at the lubricated liquid level of housing inner chamber when above, the lubricant oil that splashes also can be lubricated deep groove ball bearing, therefore speed reducer also can realize universal installation at any angle, speed reducer easy to use and flexible.
Description of drawings
Accompanying drawing 1 is the structural representation of worm-gear speed reducer in conventional art.
Accompanying drawing 2 is the most preferred embodiment structural drawing of reinforced universal installation worm-gear speed reducer described in the utility model.
