Description
Technical field
The utility model relates to a kind of speed reducer of being convenient to assemble, and belongs to the technical field of motor reduction gearbox.
Technical background
Manyly between the casing of speed reducer and the case lid tapped hole is set on casing, and counterbore is set on case lid by the screw assembling, screw passes counterbore and cooperates with tapped hole on the casing, thereby casing and case lid are assembled together.Usually, tapped hole and counterbore that many teams cooperate like this need be set on casing and case lid, when assembling, each double thread hole and counterbore all need be aimed at and just can be carried out the screw assembling, above-mentioned assembly manipulation need spend the more time, assembling inconvenience, thus caused the low problem of manufacturing efficiency.
Summary of the invention
The utility model purpose is to provide a kind of speed reducer of being convenient to assemble that improves the efficiency of assembling of speed reducer, has solved the assembling inconvenience that existing speed reducer exists, thereby has caused manufacturing efficiency to hang down inferior problem.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises casing, case lid with the casing assembling, be arranged at reduction gear and shaft in the casing, described case lid is provided with out axis hole, describedly go out the center of circle that axis hole departs from case lid and be provided with, be provided with two locating studs on the fitting surface of described casing and case lid, correspondingly be provided with two positioning holes that cooperate with locating stud on case lid, the center of circle of described two positioning holes becomes triangle to arrange with the center of circle that goes out axis hole.During assembling, only need shaft is passed the axis hole that of case lid, then the locating stud of casing is cooperated with positioning hole on the case lid, can realize the three points location between casing and the case lid, then just can by screw casing and case lid be locked easily, improve the efficient of assembling, be convenient to assembling.
As preferably, described cabinet exterior is corresponding to the other lower recess portion that is provided with of locating stud, and described case lid is provided with the corresponding depressed part of going up near positioning hole is other.Wherein, the lower recess portion on casing and the case lid and the lower recess portion on the case lid can indicate the position of positioning hole on the position of locating stud on the casing and the case lid on the one hand, and what also be convenient on the other hand point puts into, thereby is convenient to the assembling and the dismounting of speed reducer.
Therefore, the utlity model has the efficiency of assembling that can improve speed reducer, characteristics such as easy accessibility.
