Abstract
The utility model relates to a worm wheel in mechanical transmission, which is arranged on a speed reducer and is composed of a wheel edge and a wheel core which are inlaid and connected together through a group of a notch and a lug boss which are arranged on the inner and the outer circumferences; the wheel core selectively uses cast iron to save copper alloy materials, and the cost is low; the notch and the lug boss of the wheel edge and the wheel core are inlaid and connected, and the manufacture time is saved.
Description
The utility model relates to the worm gear in the mechanical transmission, specifically is a kind of worm gear in the speed reducer.
Existing worm gear has monolithic construction and fabricated construction, and monolithic construction is that worm gear is made with Cuprum alloy, the cost height, and the wheel rim of fabricated worm gear is connected with the core wheel drive fit, and manufacture difficulty is big.
The purpose of this utility model provides a kind of cost low, easily the worm gear of making.
The technical pattern scheme of this worm gear includes core wheel and wheel rim, and characteristics are that the outer garden of core wheel has one group of recess on week, in the wheel rim garden have on week one group with core wheel on the corresponding boss of recess, wheel rim is linked together by recess and boss castingin with core wheel.
This worm gear core wheel outer garden week is connected with the boss castingin with the interior garden Zhou Caiyong recess of wheel rim, and adopt drive fit to connect than prior art and have following advantage: fabrication and processing is simple, and easily, machining period shortens, thereby reduces production costs.
According to accompanying drawing, embodiment of the present utility model is described now.
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model sectional view.
Fig. 3 is another embodiment's of the utility model a topology view.
Fig. 4 is another embodiment's sectional view.
The outer garden week of the core wheel 2 of worm gear goes up symmetry and is evenly equipped with one group of recess 3, these group recess 3 numbers can have 4,6 or 8, the interior garden of wheel rim 1 has on week and recess 3 corresponding one group of boss 4, its number is also corresponding identical with recess 3, core wheel 2 is selected cast iron for use, wheel rim is a bronze, and they link together with boss 4 castingins by recess 3.
Another embodiment of the present utility model is by Fig. 3 and shown in Figure 4: be distributed on the one group recess garden hole 5 of core wheel 2 outer gardens on week, number can be selected 4,6 or 8 for use, the interior garden of wheel rim 1 also is equipped with corresponding boss garden awl 6 or boss garden post 6 on week, core wheel 2 and wheel rim 1 are bored 6 castingins by hole, recess garden 5 and boss garden and be connected and make worm gear.
