Abstract
A combined duplicate gear comprises an adjusting shaft, a first combined gear body and a second combined gear body, wherein the first combined gear body is fixedly connected to a sleeve in a sleeved mode, the sleeve protrudes out of one side of the second combined gear body, a bearing is arranged in an inner cavity of the sleeve of the second combined gear body, and the adjusting shaft is connected to an inner cavity of the bearing in a sleeved mode. The first combined gear body is provided with a position hole matched with the outer wall of the sleeve of the second combined gear body, and the first combined gear body and the second combined gear body are circumferentially and fixedly connected through a key and are axially and fixedly connected through a screw. Four deep groove ball bearings are arranged in the sleeve of the second combined gear body in parallel, and the inner rings of the bearings are axially fixed through a screw and a compressing gasket at the end portion of the adjusting shaft. The combined duplicate gear has the advantages that the gear bodies of the combined duplicate gear can be machined by the adoption of a gear hobbing, the production efficiency is high, the situation that due to scrapping of one gear body, the whole gear is scrapped in the production process is avoided, and the scrap cost is reduced.
Description
Technical field
The utility model relates to the component of machine field, is specifically related to a kind of duplicate gear.
Background technique
Duplicate gear is widely used in some gears, and it mainly adopts the processing method (can not realize with hobbing method for processing) of gear shaping when manufacturing, and the working efficiency of Gear Shaping is very low, and cost of production is high, is not suitable for producing in enormous quantities.
The model utility content
For existing above-mentioned deficiency, this practicality provides a kind of combined type duplicate gear.
To achieve these goals, the technological scheme that its technical problem that solves the utility model adopts is: a kind of combined type duplicate gear, comprise adjusting axle, the first built-up gear, the second built-up gear, described the first built-up gear is fixedly sleeved on the side-prominent sleeve of the second built-up gear one, described the second built-up gear barrel bore is provided with bearing, and described bearing cavity is socketed with adjusting axle.
Be provided with the positioning hole that matches with the sleeve outer wall of the second built-up gear on described the first built-up gear, circumferentially be fixedly connected with by key between described the first built-up gear and the second built-up gear, be fixedly connected with by screw axial.
Be set side by side with four deep groove ball bearings in described the second built-up gear sleeve, screw and the packing washer axial restraint of described bearing inner race by being arranged on the adjusting axle end.
The beneficial effects of the utility model: the gear of this combined type duplicate gear of the present utility model can adopt gear hobbing processing, and manufacturing efficiency is high, has also avoided scrapping because of a gear in process of production and causing integral body to be scrapped, and has reduced the discard cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
