Abstract
The invention discloses an improved structure of a minitype planet gear speed changing box. The structure comprises a box body, a shell and a planet gear mechanism, wherein the shell is composed of a box cover; and the planet gear mechanism is arranged in the shell. The improved structure is characterized in that the box body and the box cover are riveted through a plurality of rivets (1), and the box body and the box cover are provided with rivet holes (1) corresponding to the rivets (1). The improved structure of the minitype planet gear speed changing box provided by the invention has the advantages of simple structure, and is convenient to produce and assemble, the product assembling procedure and time can be reduced, the working amount can be reduced, and the production efficiency is improved.
Description
Technical field
The present invention relates to planetary transmission.
Background technique
Existing planetary transmission is no matter be large-scale or small-sized, its casing is connected with case lid and is all adopted screw to connect, and the planetary pinion lower cover in gear-box is arranged on case lid by screw, and is cumbersome during these spline structure production and assembly, increase workload, extended the built-up time of product.
Summary of the invention
Technical problem to be solved by this invention just is to provide a kind of improved structure of small planetary gear transmission, has simple in structurely, and production and assembly are advantage easily, can reduce assembling product operation and time, reduces workload, enhances productivity.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: a kind of improved structure of small planetary gear transmission, comprise the housing that is formed by casing and case lid and be located at planetary gears in housing, it is characterized in that: described casing and case lid are by some rivet one riveted joints, and casing and case lid are provided with the rivet hole corresponding with rivet one one.
Preferably, described planetary gears comprises upper cover and the lower cover that connects by linkage structure, and some planetary pinions are installed between upper cover and lower cover.
Preferably, described lower cover edge is provided with some positioning holes, and casing and case lid are provided with the riveted holes corresponding with described positioning hole two, the located lateral that lower cover is realized in gear-box by rivet two.
Further, described upper cover and lower cover are connected to respectively on casing and case lid, planetary gears by under the positioning hole, upper cover, lower cover and the rivet two that cover realize location horizontal and vertical in housing.Structural design is ingenious, simplifies assembling procedure, reduces workload and time, raises the efficiency.
Described rivet one is tube-in-tube structure with rivet two.
Preferably, described linkage structure is rivet, and upper cover and lower cover be by described rivet, upper cover with under cover and be provided with the riveted holes that installs rivet.
Preferably, described rivet is tube-in-tube structure.
Preferably, described rivet hole cross section is the T font, makes its end face after rivet not protrude the end face of upper cover and lower cover.
Improved, described planetary pinion is positioned in space between upper cover and lower cover by rivet.
The present invention is with simple in structure, and production and assembly are convenient, can reduce the assembling product time, reduces the employee work amount, is fit to very much miniature planetary gear box, and after using, manufacturing efficiency obtains the raising of highly significant.
