Abstract
The utility model relates to a thin sheet shell gearbox, which belongs to the variable speed driving device. The utility model is mainly used for agricultural machinery. The utility model is characterized in that the gearbox is composed of a left and a right box shells which are butt jointed and are moulded by thin steel plates, a drive shaft and accessories thereof which are arranged in the left and the right box shells, various gear speed changing pieces, and screws which are distributed along the periphery of the box shells, integrating with the box shells. The utility model has the advantages of small size, light weight, steel saving, low cost, simple processing technology, accurate size, beautiful appearance, uniform size, more convenience for mass production, etc.
Description
A kind of thin sheet casing gearbox belongs to the variable speed drive technical field, is mainly used in farm machinery.
The used speed-changing gear box of farm machinery all is the casing that cast iron, cast aluminium or Plate Steel are welded in the prior art, casting or postwelding fine finishing again.This casing is not only heavy, and outward appearance is not beautiful, size inaccuracy, and processing technology complexity, cost height.
The purpose of this utility model is to provide a kind of volume little, in light weight, and processing technology is simple, and size is accurate, and is aesthetic in appearance, and cost is low, the thin sheet casing gearbox that is easy to produce in enormous quantities.
According to the compression molding basic principle, at the subject matter that exists in the prior art, basic design of the present utility model is to be molded into the opposite housing with sheet metal, and the border stamping goes out attachment hole, is connected to become a monolithic case with screw behind the speed change of packing into the parts.
Thin sheet casing gearbox described in the utility model, by left and right box shell 1 and 2 and dress transmission shaft and annex 3 and various gear graduation part 4 within it constitute, it is characterized in that this gearbox its above-mentioned left and right box shell 1 and 2 is with sheet metal is molded into opposite, and the two is interconnected as an integral body mutually by the screw 5 that passes along the uniform attachment hole of they peripheries.
Outstanding advantage of the present utility model is: in light weight because its housing is to adopt the sheet metal mold pressing one-time formed so not only volume is little, save steel, cost is low, and processing technology is simple, and size is accurate, aesthetic in appearance, use Mould Machining, the size unification is convenient to produce in enormous quantities.
Accompanying drawing 1 cuts open schematic representation for one of the utility model most preferred embodiment assembling back bulk shape side-looking office;
Accompanying drawing 2 is Fig. 1 schematic top plan view.
Further describe structure characteristic of the present utility model as follows with most preferred embodiment in conjunction with the accompanying drawings: in left and right box shell 1 and 2 with the opposite of the many uniform attachment holes of sheet metal compression molding week astragal, the gear of packing known transmission shaft and other class annex 3 into and being contained on the axle reaches after other gear iso-variable velocity parts 4 that are meshed with it, and being connected by the screw 5 that passes above-mentioned each attachment hole becomes an integral body.
