Abstract
The utility model relates to a universal thrust type coupler. The universal thrust type coupler is suitable for connection of a transmission shaft which is low in speed and heavy in load in a bad work environment. The universal thrust type coupler comprises two connecting shaft heads, a connecting shaft and a connecting shaft sleeve. The two connecting shaft heads are respectively connected with the connecting shaft and the connecting shaft sleeve. The connecting shaft sleeve covers the connecting shaft. The shape of a cross section at any position of the connecting shaft is similar to that of a cross section of an inner cavity at any position of the connecting shaft sleeve, and the size of the cross section at any position of the connecting shaft is smaller than that of the cross section of the inner cavity in any position of the connecting shaft sleeve. The universal thrust type coupler is simple in structure, easy to manufacture and apply, time-saving, labor-saving, capable of saving in manufacturing cost and high in cost performance.
Description
Technical field
The utility model relates to a kind of universal push type coupling, and this universal push type coupling is adapted to the low speed under the work under bad environment, the connection of heavy load transmission axle.
Background technique
At present, be connected with transmitting torque with taper pin or key with axle by cylindrical sleeve usually between the connection spindle nose.When connecting with taper pin, torque transmitted is less; When connecting with key, torque transmitted is bigger.The coupling that uses key to connect mainly is to connect by spline, and splined shaft and sleeve pipe need be made by rough forging, machining and heat treatment, in technology higher requirement are arranged, and waste time and energy, in the process of producing, consume a large amount of manpower and materials, increased cost of production.
The model utility content
Technical problem to be solved in the utility model provides a kind of universal push type coupling, and it can be come into operation and can be applicable to rugged environment by production fast.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of universal push type coupling, comprise that two connect spindle nose, coupling shaft, connecting bushing, described two connection spindle noses link to each other with described connecting bushing with described coupling shaft respectively, described connecting bushing is enclosed within on the described coupling shaft, the cross section at any place of described coupling shaft is similar to any place's shape of cross section of the inner chamber of connecting bushing, and the cross-sectional dimension at any place of described coupling shaft is less than any place's inner chamber cross-sectional dimension of connecting bushing.
The beneficial effects of the utility model are: it is simple in structure, is easy to make and implement, and is time saving and energy saving, has saved cost of production, the cost performance height.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the any place's cross section of the cross section at any place of described coupling shaft and the inner chamber of connecting bushing is square or triangle, the cross-sectional dimension at any place of described coupling shaft be connecting bushing any place's cross-sectional dimension of inner chamber 2/3rds to 9/10ths, place, slit between described coupling shaft and the described connecting bushing is provided with the gland that shape and size with it are complementary, described gland inserts coupling shaft and connecting bushing interconnects in the slit at place, be equipped with screw on described gland and the described connecting bushing, described gland is by being bolted on described connecting bushing pullover.
The beneficial effect that adopts above-mentioned further scheme is with more stable being fixed in the connecting bushing of coupling shaft, has reduced vibrations, frictional heating and noise.

Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not for limiting scope of the present utility model.
As shown in Figure 1, the utility model comprises that two connect spindle nose 3, coupling shaft 1, connecting bushing 2, described two connection spindle noses 3 link to each other with described connecting bushing 2 with described coupling shaft 1 respectively, described connecting bushing 2 is enclosed within on the described coupling shaft 1, as shown in Figure 2, the cross section at described coupling shaft 1 any place is similar to any place's shape of cross section of the inner chamber of connecting bushing 2, and the cross-sectional dimension at described coupling shaft 1 any place is less than any place's inner chamber cross-sectional dimension of connecting bushing 2, Fig. 3 is the cross sectional representation of coupling shaft, the cross section at described coupling shaft 1 any place and any place's cross section of the inner chamber of connecting bushing 2 are square or triangle, the cross-sectional dimension at described coupling shaft 1 any place be connecting bushing 2 any place's cross-sectional dimension of inner chamber 2/3rds to 9/10ths, place, slit between described coupling shaft 1 and the described connecting bushing 2 is provided with the gland 4 that shape and size with it are complementary, described gland 4 inserts coupling shaft 1 and connecting bushing 2 interconnects in the slit at place, be equipped with screw on described gland 1 and the described connecting bushing 2, described gland 4 is fixed on described connecting bushing 2 pullover by bolt 5.
During use, determine the distance of the two articles that need be connected, then coupling shaft 1 is inserted in the connecting bushing 2, adjust the length of inserting in the coupling shaft, insert gland 4 then and also fix with bolt 5, will connect spindle nose 3 and link to each other with quilt even thing respectively, so realize transmitting the effect of moment of torsion.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
