Abstract
The invention discloses a locknut. A clearance is reserved on a nut body; a first locking hole and a second locking hole are respectively arranged on the nut body of two sides of the clearance. A torque limiter which is also arranged on the nut body comprises a connecting sleeve; two sides of the connecting sleeve are respectively provided with a friction plate; a clamp ring is sleeved on the outer side of one of the friction plates; a disc spring is arranged on the outer side of the camp ring; the locknut is arranged on the outer side of the disc spring, wherein, the friction plates, the clamp ring, the disc spring and the locknut are sleeved on a pole part of the connecting sleeve; the pole part of the connecting sleeve is provided with screw threads; and the locknut is the locknut referred above. The locknut can realize a function of over-torque protection in a transmission system; after torque adjustment is realized, the torque can not be changed by the loosing of the nut.
Description
Technical field
The present invention relates to a kind of limiter of moment, and the locking nut that is used for limiter of moment.
Background technique
Limiter of moment is used for being connected of prime mover and other transmission paries, can not burn out because of miscellaneous part abnormal operating state on its Transmitted chains causes prime mover stall by limiter of moment protection prime mover.
Summary of the invention
The purpose of this invention is to provide a kind of novel limiter of moment and locking nut.
The objective of the invention is to be achieved through the following technical solutions:
A kind of locking nut, its body is provided with the gap, is respectively equipped with first, second locking hole on the nut body of the both sides in this gap.
Wherein, described first, second locking hole at least one be screw.
The present invention also comprises a kind of limiter of moment, comprise a connecting sleeve, respectively be provided with a friction plate in the both sides of this connecting sleeve, a hold-down ring is set in the outside of one of them friction plate, and a dish spring is located at the outside of this hold-down ring, and a locking nut is located at the outside of this dish spring, wherein, described friction plate, hold-down ring, dish spring and locking nut all are enclosed within the bar portion of this connecting sleeve, and the bar portion of connecting rod cover is provided with screw thread, the aforementioned locking nut of described locking nut.
Wherein, the locking hole at this locking nut is provided with bolt and packing ring.
Positive progressive effect of the present invention is: can realize the function of crossing force moment protection in the transmission system, and after can realizing torque adjusting, its moment can not change because of getting loose of nut.
Description of drawings
Fig. 1 is in the embodiment of the invention 1, the positive cross-sectional schematic of locking nut.
Fig. 2 is in the embodiment of the invention 2, and schematic representation is partly cutd open in the side of limiter of moment.
Fig. 3 is in the embodiment of the invention 2, the limiter of moment front schematic view.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technological scheme of the present invention in detail.
As shown in Figure 1, a kind of locking nut, its body 100 is provided with gap 110, processes one first locking hole 120, second locking hole 130 respectively on the nut body of the both sides in this gap.Wherein at least one is a tapped hole, and another can be a through hole.In the present embodiment, first locking hole 120 is a through hole, and second locking hole 130 is a tapped hole.
Around the nut blind hole is set, inserts crow bar when being used for nut screwing clamping, make things convenient for tightening of nut.
Shown in Fig. 2,3, a kind of limiter of moment, two friction plates 5 are placed on the bi-side of sprocket wheel 1, cover is through the bar portion 61 of connecting sleeve 6, bar portion 61 is provided with screw thread, dish spring 3 and hold-down ring 4 are enclosed within one of them friction plate 5 outside and compress with friction plate 5, and the outside of dish spring 3 is provided with a locking nut 2, and this locking nut 2 is embodiment's 1 described locking nut.
The pressure that adjusting hold-down ring 4 by rotational lock nut 2 and friction plate are 5 is to reach desired friction torque.
By tightening of bolt 7 and packing ring 8, can be locked in the bar portion 61 of connecting sleeve 6 regulating locking nut, play the effect of loosening locking.And, by the screwing force of bolt 7, make the gap smaller of locking nut 2, thereby the screw thread on the locking nut 2 and the screw thread of bar portion 61 are pressed together, can not make the locking nut 2 and the screw thread of connecting sleeve 6 produce slide relative because of the rotation of limiter of moment, thereby play locking effect.
Claims (4)
1, a kind of locking nut is characterized in that, its body is provided with the gap, is respectively equipped with first, second locking hole on the nut body of the both sides in this gap.
2, locking nut according to claim 1 is characterized in that, at least one is screw for described first, second locking hole.
3, a kind of limiter of moment, it is characterized in that, it comprises a connecting sleeve, respectively is provided with a friction plate in the both sides of this connecting sleeve, and a hold-down ring is set in the outside of one of them friction plate, a dish spring is located at the outside of this hold-down ring, a locking nut is located at the outside of this dish spring, and wherein, described friction plate, hold-down ring, dish spring and locking nut all are enclosed within the bar portion of this connecting sleeve, the bar portion of connecting sleeve is provided with screw thread, and described locking nut is the described locking nut of claim 1.
4, limiter of moment according to claim 3 is characterized in that, is provided with bolt and packing ring at the locking hole of this locking nut.
