Abstract
The patent of the utility model relates to a reduction gear, in particular to an output shaft mechanism for a worm-gear reduction gear. The output shaft mechanism comprises a box body, wherein an output shaft is arranged in the box body; an output flange is arranged on the side wall of the box body; one end of the output shaft outwardly extends to the box body and is arranged in the output flange; a worm is sleeved on the output shaft; bearings are respectively arranged at the two ends of the worm, and are sleeved with the output shaft; and the worm is meshed with a gear in the box body. The output shaft mechanism provided by the utility model has simple structure, high mounting precision, and good use effect.
Description
Technical field
The utility model patent relates to a kind of speed reducer, relates in particular to a kind of output shaft mechanism that is used for worm-gear speed reducer.
Background technique
Output shaft mechanism in the speed reducer of present existing technology, complex structure, and also operational effect is relatively poor relatively.
Chinese patent CN201020627721.2; Disclose a kind of accurate worm-gear speed reducer, comprise casing, end cap and be separately fixed at input flange, the capping of casing both sides, two helical pitch worm gear pairs are set in casing; Wherein two external input shafts of helical pitch worm screw; The two ends of two helical pitch worm screws are bearing in the casing by bearing, and the worm drive output sleeve is between the bearing and capping of two helical pitch worm screws rear end, all be provided with automatic adjustment spring between the bearing of two helical pitch worm screw front ends and the input flange.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the existing technology, provides a kind of simple in structure, and the outstanding output shaft mechanism that is used for worm-gear speed reducer of using effect.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of output shaft mechanism that is used for worm-gear speed reducer comprises casing, is provided with output shaft in the described casing; The sidewall of described casing is provided with output flange; One end of described output shaft extends outside casing and is located in the output flange, is with worm gear on the described output shaft, and the two ends of described worm gear are respectively equipped with bearing; Described bearing and output shaft socket-connect, and described worm gear is meshed with the interior worm screw of casing.
This is simple in structure, and assembly precision is high, and running steadily.
As preferably, described bearing and worm gear connect through back-up ring, and the head of described output shaft is provided with flat key, and the head of output shaft extends outside the output flange.
As preferably, described output flange and casing fix through bolt.
Therefore, the output shaft mechanism that is used for worm-gear speed reducer of the utility model, simple in structure, installation precision is high, and using effect is good.
