Abstract
The utility model discloses a duplicate gear, which includes an output gear, an input gear, an inner bore and lightening holes, wherein eight lightening holes are arranged in the output gear and symmetrically and evenly distributed on the output gear taking a circle center of the output gear as the center. The duplicate gear has the benefits that eight lightening holes are arranged in the output gear, so that the effect of lightening the load of a product can be realized, and acts as a strengthening rib.
Description
Technical field
The utility model relates to a kind of duplicate gear.
Background technique
Gear transmission is the most widely used kind of drive in the mechanical transmission, and it can guarantee stable transmission, has the transmission efficiency height; The advantage that life-span is long; The production precision of gear is high, and the deficiency that the gear that adopts steel part to process exists is that low-cost height of work efficiency and precision are low, and to adopt the advantage of the gear that the powder metallurgy manufacturing forms be that cost is low at present and adopt; Efficient is high, and precision is high.Employed duplicate gear is not provided with lightening hole in application, causes load on the whole to be laid particular stress on, and kinetic equation loss is than higher.
The model utility content
The purpose of the utility model is to provide a kind of duplicate gear, lays particular stress on to solve the duplicate gear overall load, and kinetic equation loss compares problem of higher.
The purpose of the utility model is to realize through following technological scheme:
A kind of duplicate gear comprises output gear, input gear, endoporus and lightening hole, it is characterized in that said output gear is provided with 8 lightening holes, and said lightening hole is that the center is distributed on the output gear symmetrically and evenly with the center of circle of output gear.
For realizing the function of the utility model further, the number of gears of said output gear is 12, and the number of gears of input gear is 58.Said output gear is connected through gear shaft with the input gear.
The beneficial effect of the utility model is: output gear is provided with 8 lightening holes, plays the effect of the load that alleviates product, plays the effect of stiffening rib simultaneously again.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the said duplicate gear plan view of the utility model;
1, output gear, 2, lightening hole, 3, endoporus, 4, the input gear.
Embodiment
As shown in Figure 1; Provided a specific embodiment of the utility model; Among the figure; Comprise output gear 1, input gear 4, endoporus 3 and lightening hole 2, said output gear 1 is provided with 8 lightening holes 2, and said lightening hole 2 is that the center is distributed on the output gear 1 symmetrically and evenly with the center of circle of output gear 1.The number of gears of said output gear 1 is 12, and the number of gears of input gear 4 is 58.Said output gear 1 is connected through gear shaft with input gear 4.Input gear 4 input speeds, output gear 1 output speed, said endoporus 3 are to be placed on the gear shaft core, lightening hole 2 plays the effect of the load that alleviates product, plays the effect of stiffening rib simultaneously again.After the gear weight reduction, improved transmission efficiency effectively.Because the advantage of the gear that the manufacturing of employing powder metallurgy forms is that cost is low, efficient is high, and precision is high, and therefore, the duplicate gear of the utility model forms for the powder metallurgy manufacturing.
Claims (3)
1. a duplicate gear comprises output gear, input gear, endoporus and lightening hole, it is characterized in that said output gear is provided with 8 lightening holes, and said lightening hole is that the center is distributed on the output gear symmetrically and evenly with the center of circle of output gear.
