Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, a kind of coupling band, comprising: the first tube body 100, the second tube body 200, torsional protector and sealing
Component, the end of first tube body 100 are provided with stepping ends, and the stepping ends include wearing portion 110 and mounting portion
120, the portion 110 that wears is threaded through in second tube body 200, torsional protector setting it is described wear portion 110 with
Between the inner wall of second tube body 200, the seal assembly be set on the mounting portion 120 and with the second tube body 200
End contradicts connection.
It is worth noting that, existing coupling sleeve, at both ends, there are two the axis holes worn for axis for tool herein, in rotation,
Driving shaft naturally can drive driven shaft to rotate, such structure, as soon as since coupling band is entirety, so natural
It does not need to be sealed, and if torque protection to be realized, it is necessary to the first tube body 100 and second is set by coupling band
Tube body 200, the first tube body 100 and the second tube body 200 respectively with driving shaft and driven axis connection, and the first tube body 100 with
Torsional protector is connected between second tube body 200, can realize that torque protection acts in this way, and again in the first tube body
100 and second are arranged seal assembly between tube body 200, then when the first tube body 100 dallies, foreign matter are avoided to enter.
Furthermore, it is understood that being exactly to set ladder-like for the end of the first axle body, front end wears end to be lesser, so
It can wear into the second tube body 200, and the second tube body 200 and wear and be of virtually certain gap between portion 110, gap
It is inside provided with torsional protector, when the portion that wears 110 is worn into the second tube body 200, mounting portion 120 actually just corresponds to the
Seal assembly is arranged on mounting portion 120 at this time for the end face of two tube bodies 200, when the idle running of the first tube body 100, due to first
It can relatively rotate between tube body 100 and the second tube body 200, so will form certain gap between the two, due to sealing
The effect of component can seal up the gap between the first tube body 100 and the second tube body 200.
As shown in Figure 1, on the basis of the above embodiment, the torsional protector includes friction plate 310 and adjusts
Bolt 320, the setting of friction plate 310 are worn between portion 110 and second tube body 200 described, the adjusting bolt 320
It is threaded through on second tube body 200 and is contradicted with the friction plate 310 and connected.
Preferably, torsional protector works indeed through the principle of frictional force, when turning for the portion that wears 110
When dynamic torsion is excessive, frictional force can not link together the second tube body 200 and the first tube body 100, and the first tube body 100 is just at this time
It can dally, also, the torque magnitude of torsional protector is adjustable, frictional force can be changed by adjusting bolt 320 and wear portion 110
Between pressure, to change the frictional force size of friction plate 310.
As shown in Figure 1, on the basis of the above embodiment, the seal assembly includes rotating ring 410 and stationary ring 420,
The rotating ring 410 is set on the mounting portion 120, and the stationary ring 420 is set on second tube body 200, the rotating ring
410 contradict connection with the stationary ring 420.
Preferably, seal assembly is mainly to pass through rotating ring 410 and the realization sealing of stationary ring 420, rotating ring 410 and the first tube body
100 is fixed, and stationary ring 420 and the second tube body 200 are fixed, and keep sealing by contact surface between rotating ring 410 and stationary ring 420,
When the idle running of the first tube body 100, rotating ring 410 rotates on stationary ring 420, so being capable of forming sealing structure.
As shown in Figure 1, on the basis of the above embodiment, the seal assembly further includes counterbalance spring 430 and consolidates
Reservation 440, the fixing seat 440 are fixed on second tube body 200, the both ends of the counterbalance spring 430 respectively with it is described
Fixing seat 440 and the stationary ring 420 contradict connection.
Preferably, it is relatively rotated between rotating ring 410 and stationary ring 420 in practice as continuous, abrasion can be generated, and compensated
Spring 430 contradicts stationary ring 420 closely on rotating ring 410, eliminates gap between the two for pushing stationary ring 420.
As shown in Figure 1, on the basis of the above embodiment, between the rotating ring 410 and the mounting portion 120 and institute
It states and is provided with sealing ring 450 between stationary ring 420 and second tube body 200.
It can guarantee the leakproofness between rotating ring 410 and mounting portion 120 in this way, additionally it is possible to guarantee stationary ring 420 and the second pipe
Leakproofness between body 200.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
