Abstract
The utility model discloses a clamping nut connecting structure, which comprises a shaft and a hub and is characterized in that a clamping nut is arranged between the shaft and the hub and is provided with a front conical compression ring and a back conical compression ring; two sides of the clamping nut are provided with an external elastic ring and an internal elastic ring; the inner surfaces of the internal and external elastic rings have a conical surface structure; and the internal and external elastic rings are contacted with the front and back conical compression rings through compression bolts. The clamping nut connecting structure has the beneficial effects that a keyless connecting device for transmitting a load can be realized through pressure and friction generated between accommodating surfaces by fastening high strength bolts through the clamping nut, so that a machine part is connected with the shaft to transmit the load, and the clamping nut connecting structure has long service life, high strength and the like.
Description
Technical field
The utility model relates to a kind of expansion sleeve linkage structure, and it relates generally to the field that is in transmission connection that connects without key.
Background technique
In the connection of heavy machinery, the connection of wheel and axle is most important, by using expansion sleeve only to make the pressure and the frictional force that produce between female surface realize a kind of keyless joint device that load transmits by tightening high-strength bolt, to realize connecting of parts (such as gear, flywheel, belt pulley etc.) and axle, in order to transfer charge, have long service life, intensity advantages of higher, compare the axle of conventional mounting expansion set and the processing in hole and unlike interference fit, require high-precision manufacturing tolerances, need not heat when expansion set is installed, cooling or pressurized equipment, easy to use.
Summary of the invention
For the technological deficiency that above-mentioned the said goods exists, the utility model provides a kind of simple in structure, long service life, a kind of expansion sleeve linkage structure that intensity is high.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of expansion sleeve linkage structure comprises: axle and wheel hub is characterized in that: be provided with expansion sleeve in the middle of described axle and the wheel hub, described expansion sleeve is provided with front taper pressure ring and rear taper pressure ring, and described expansion sleeve both sides are equipped with outer elastic ring and interior elastic ring.
The internal surface of described inside and outside elastic ring is the conical-surface type structure.
Described inside and outside elastic ring contacts with forward and backward taper pressure ring by hold-down bolt.
The beneficial effects of the utility model are: can only make the pressure and the frictional force that produce between female surface realize a kind of keyless joint device that load transmits by tightening high-strength bolt by using expansion sleeve, to realize connecting of parts and axle, in order to transfer charge, have long service life, intensity advantages of higher.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1: a kind of expansion sleeve linkage structure, comprise: axle 1 and wheel hub 2, it is characterized in that: axle 1 and the wheel hub 2 middle expansion sleeves 3 that are provided with, expansion sleeve 3 is provided with front taper pressure ring 4 and rear taper pressure ring 5, expansion sleeve 3 both sides are equipped with outer elastic ring 6 and interior elastic ring 7, and interior elastic ring 7, outer elastic ring 6 contact with front taper pressure ring 4, rear taper pressure ring 5 by hold-down bolt 8.
The utility model makes such enforcement: the internal surface of interior elastic ring 7 and outer elastic ring 6 has certain conical surface, be connected with front and back taper pressure ring 4,5 by hold-down bolt 8, when hold-down bolt 8 is strained front and back taper pressure ring 4,5, distance between it reduces, and mutually compresses with inside and outside elastic ring 7, at this moment, interior elastic ring 7 pressurized internal diameters shrink, outer elastic ring 6 pressurized external diameters swell, and make wheel hub 2, expansion sleeve 3, axle 1 produce frictional force and mutually are tightened to one, thereby reach the function of transmitting torque.
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technological scheme of unrestricted the utility model; Therefore, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
Claims (3)
1. expansion sleeve linkage structure, comprising: axle and wheel hub is characterized in that: is provided with expansion sleeve in the middle of described axle and the wheel hub, described expansion sleeve is provided with front taper pressure ring and rear taper pressure ring, and described expansion sleeve both sides are equipped with outer elastic ring and interior elastic ring.
2. described a kind of expansion sleeve linkage structure according to claim 1, it is characterized in that: the internal surface of described inside and outside elastic ring is the conical-surface type structure.
