Abstract
The utility model provides a gapless gear worm speed reducer. A worm gear output shaft with a bearing, anoil seal and a bearing cap is installed at the medium of the body, and the worm gear is sleeved on the shaft. A worm screw with a bearing and a worm gear meshed with each other is installed at the lower of the body, a receiving disk, a speed reducer and an electric motor are installed at one end from the left to the right, an active bevel gear is installed on the other top end, an adjustment bevel gear meshed with the active bevel gear is installed at one end of the adjustment worm screw meshed with the worm gear in longitudinal direction, the lower of the adjustment bevel gear has a adjusting nut, the upper has a adjustment nut, and the other end has a bearing and a top bearing cap. A air releasing cap and a suspension ring is fixed at the top of the body, and an oil level observation window is fixed at lower of one side of the body. The gapless gear worm speed reducer achieves gapless state after adjusting intermeshing gap. Different drive manners can be implemented by different drive classes for satisfying work require.
Description
Technical field
The utility model relates to a kind of mechanical field, especially the non-clearance worm and gear speed reducer.
Background technique
At present, worm-gear speed reducer, its worm gear and worm screw be through separately Bearing Installation, and bearing is installed in respectively in the bearing support on the casing, and worm gear and worm screw have the fixed center distance.Owing to have the making tolerance and the build-up tolerance of worm and gear, between worm gear and worm screw, can produce the back lash, this back lash the worm-gear speed reducer output shaft is existed and input shaft between reaction insensitive, influenced by load institute application of force square to make little angle reciprocally swinging etc.When this worm-gear speed reducer during as the higher actuator of precision prescribed, this back lash will influence the operating accuracy of actuator.The application of the backlash mechanism of worm and worm gear group elimination in the past is common in the design of index plate, this is designed to the anti-back clearance of twin worm mechanism, when power transmits via a worm screw, another root worm screw also has an opposition and output worm gear to offset to eliminate backlash, but this kind design need be simultaneously by adorning two worm screws, because two parallel installations of worm screw, a pair of gear centre distance that connects two worm screws is far away, cause body huge, install inconvenient.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel non-clearance worm and gear speed reducer, and this non-clearance worm and gear speed reducer reaches no gap state after the adjustment of meshing gap.According to different needs, realize the different kinds of drive by adorning different transmission ranks, satisfy the operating mode needs.
The technological scheme that its technical problem that solves the utility model adopts is: the non-clearance worm and gear speed reducer, it is to be equipped with at the middle part of body that tape spool holds and the worm gear output shaft of oil sealing, bearing cap, is with worm gear on the axle.The bottom of body is equipped with tape spool and holds and the worm gear engaged worm, its end is equipped with from right-to-left and connects dish, speed reducer, motor, drive bevel gear is equipped with on another top, vertically on the adjusting worm screw that meshes with worm gear, one end is equipped with the cone governor gear with drive bevel gear engagement, adjusting nut is arranged below the cone governor gear, and the nut of adjustment, bearing are arranged above, the other end has bearing, the top bearing cap.Vent cover, suspension ring are arranged at the body top, and oil level glass is arranged at the bottom of body one side.
This non-clearance worm and gear speed reducer is made up of single worm gear pair transmission of twin worm and regulating mechanism.The single worm gear pair transmission of described twin worm is by identical two worm screws and mutually meshing being installed on the body of worm gear.Mounting type is vertically installed.Described regulating mechanism is that the bevel gear adjusting mechanism vertically is installed.
This non-clearance worm and gear speed reducer is installed the column gear transmission speed reducer on the input end worm shaft of worm reduction gear, worm reduction gear, and cycloidal planetary gear speed reducer is formed the multistage combination of large speed ratio transmission, changes the kind of drive and satisfies different operating mode needs.
The beneficial effects of the utility model are that this novel non-clearance worm and gear speed reducer reaches no gap state after the adjustment of meshing gap.According to different needs, realize the different kinds of drive by adorning different transmission ranks, satisfy the operating mode needs.
