Abstract
The utility model relates to a device for connecting a gear with a shaft. In the utility model, an inner rise sleeve 6 and an outer rise sleeve 4 are arranged between a gear 1 and a shaft 5; in order to tightly press the inner rise sleeve 6 and the outer rise sleeve 4, a pressing plate 3 which is fastened by a screw bolt 2 is arranged on the end face of the gear 1; after tight pressing, the inner rise sleeve 6 is in face contact with the outer rise sleeve 4; an included angle between the inner rise sleeve 6 and the outer rise sleeve 4 ranges from 20 to 45 DEG. The device has the advantages of flexible loading and unloading, large driving torque, and little damage to the shaft. The friction force between the inner rise sleeve and the outer rise sleeve is conveniently regulated, and thereby, torque transferred by the gear is regulated, and the gear slides when an accident occurs so that the shaft and other parts are protected.
Description
The utility model relates to the coupling arrangement of a kind of gear and axle.
On the connecting mode of existing gear and axle mainly is to connect by key, in some cases, also adopts the method for coming tightening with screw, or adopts bigger magnitude of interference to connect gear and axle.In these connecting modes, utilizing key connecting is the most frequently used method, but key connecting need process keyway respectively on gear and axle, utilizes key that gear and axle are linked up again.In the reciprocal transmission of having relatively high expectations, key is loosening easily, makes in the gear transmission process and becomes flexible, and influences transmission accuracy.And the processing keyway can destroy the Organizational Structure of axle on axle, produces stress and concentrates, and makes axle fracture in to-and-fro motion at a high speed.And adopt the gear of big interference fit and axle to need cylinder sleeve or freezing mode to install, operate very inconvenient.And it is very inconvenient when on axle, adjusting the position of gear.Though adopt fastening gear of screw and axle, also can adjust the position of gear easily, the moment of torsion of its transmission is very little, and also dallying easily influences the smart condition of transmission.
The purpose of this utility model provides a kind of easy to loading and unloading at above-mentioned the deficiencies in the prior art exactly, and driving torque is big, axle is destroyed the coupling arrangement of little a kind of gear and axle.
The purpose of this utility model can realize by following measure:
The coupling arrangement of a kind of gear and axle, it comprises gear (1), bolt (2), pressing plate (3), inner expanding sleeve (6), outer expanding sleeve (4) and axle (5), be provided with inner expanding sleeve (6) and outer expanding sleeve (4) between gear (1) and the axle (5), the end face of gear (1) is provided with the fastening pressing plate (3) of bolt (2), inner expanding sleeve (6) compresses the back with outer expanding sleeve (4) and contacts for face, and the fiery angle α of inner expanding sleeve (6) and outer expanding sleeve (4) is the 20-45 degree.Be provided with two groups of above inner expanding sleeve (6) and outer expanding sleeves (4) between gear (1) and the axle (5).
The utility model compared with prior art has the following advantages:
This structure can be installed easily; loading and unloading flexibly; driving torque is big; destruction to axle is little; and can adjust the power of rubbing between ringfeder and gear 1 and spools 5 by the degree of depth that adjusting screw 2 screws in gears 1; adjust the moment of torsion that gear can transmit, gear is skidded meeting accident, protect axle and other part.
Description of drawings is as follows:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of inner expanding sleeve 6;
Accompanying drawing 3 is the structural representation of outer expanding sleeve 4;
Accompanying drawing 4 is a kind of structural representation of the present utility model;
Accompanying drawing 5 is an another kind of structural representation of the present utility model;
Describe in detail by embodiment below in conjunction with accompanying drawing:
Claims (2)
1, the coupling arrangement of a kind of gear and axle, it comprises gear (1), bolt (2), pressing plate (3) and axle (5), it is characterized in that: be provided with inner expanding sleeve (6) and outer expanding sleeve (4) between gear (1) and the axle (5), the end face of gear (1) is provided with the fastening pressing plate (3) of bolt (2), inner expanding sleeve (6) compresses the back with outer expanding sleeve (4) and contacts for face, and the angle α of inner expanding sleeve (6) and outer expanding sleeve (4) is the 20-45 degree.
