Abstract
The utility model discloses the attachment structure of a kind of Lever Blocks brake and major axis, belong to Lever Blocks technical field.Including the brake seat being installed on major axis, inner attrition piece, ratchet and outside friction disc are set with brake seat successively, brake seat circumferentially connecting is on major axis, and the left end face of brake seat its axis hole is against on a shaft shoulder of this major axis, brake seat is provided with elastic pressed piece in the counterbore that its its right end face is opened up, the elastic pressed piece had both compressed this counterbore, was resisted against again at the axial back-up ring being installed on major axis.This brake seat circumferentially connecting is on major axis, and the brake seat is axially fixed between the shaft shoulder of major axis and shaft block ring by the pretightning force of elastic compression piece, not only eliminate the axial gap of brake seat, prevent brake seat axial float, the characteristics of this brake seat axially position is reliable is embodied, and the axis hole caused by the mismachining tolerance of its axis hole of brake seat can be made up and produces alignment error with the major axis shaft shoulder.
Description
【Technical field】
The utility model is related to the attachment structure of a kind of Lever Blocks brake and major axis, belongs to Lever Blocks technology neck
Domain.
【Background technology】
Brake seat, brake hoop, commutation ratchet, handwheel and slotted nut are installed on major axis successively, wherein, brake seat
It is to be screwed in multiple thread on major axis, and brake seat can be against on the shaft shoulder of this major axis, handwheel is placed on major axis, hand
Its axis hole left side is taken turns against on the shaft shoulder of this major axis, the right side of its axis hole of handwheel and the slotted nut positioned at major axis shaft end
Coordinate in gap, commutation ratchet is screwed on major axis by multiple thread, and commutation ratchet is connected together handwheel, brake hoop empty set
On major axis, the left end face of brake hoop is corresponding with the friction plate being placed on brake seat, and the right-hand end of brake hoop is all
Commutated to being fixed on ratchet.
Said structure is carefully analyzed, it is seen that with following technical deficiency：
There is axial movement in brake：When lifting heavy, major axis needs to rotate, and is driven and grown by the rotating forward for the ratchet that commutates
Axle is rotated, because brake seat spins with major axis multiple thread, and this causes brake seat together with friction plate axially (towards shaft end side
To) mobile, brake insensitive, braking effect is poor, cause Lever Blocks complete machine to be skidded, it is impossible to effective lifting heavy；
In use, the brake rust being easily caused including brake seat, friction plate and ratchet is dead under field rainy day occasion
Together, the multiple thread rust of the bull inner bolt hole of brake seat and major axis it is dead together with, Lever Blocks can not be used.
【Utility model content】
The deficiency existed for above-mentioned prior art, the purpose of this utility model is that providing a kind of brake seat axially determines
The attachment structure of the reliable Lever Blocks brake in position and major axis.
Therefore, the utility model provides following technical scheme：
A kind of attachment structure of Lever Blocks brake and major axis, including the brake seat being installed on major axis, braking
Inner attrition piece, ratchet and outside friction disc are set with successively on device seat, and its improvement is：Brake seat circumferentially connecting is in major axis
On, and brake seat its axis hole left end face against on the shaft shoulder of this major axis, brake seat is opened up in its its right end face
Elastic pressed piece is installed, the elastic pressed piece had both compressed this counterbore in counterbore, the axial direction gear being installed on major axis is resisted against again
At circle.
Brake hoop, commutation ratchet, handwheel and self-locking nut are also sequentially installed with major axis.Wherein, commutation ratchet passes through many
Head thread is screwed on major axis, and brake hoop empty set is on major axis, and the left end face of brake hoop is corresponding with outside friction disc, and brakes
The right-hand end of ring is fixed on commutation ratchet；Handwheel circumferentially connecting on major axis, and handwheel its axis hole left side against herein
On the shaft shoulder of major axis, the right side of its axis hole of handwheel is fixedly connected on major axis end by self-locking nut.
As preferential, the axis hole of above-mentioned brake seat is splined hole, and brake seat is by its splined hole circumferentially connecting in length
On the corresponding outer spline section of axle.
As preferential, above-mentioned elastic pressed piece is disk spring.
The utility model has the advantage that as follows with good effect：
The brake seat that prior art connects major axis using multiple thread has been abandoned, this brake seat week is the substitute is
To being connected on major axis, and the brake seat is axially fixed at the shaft shoulder and axle gear of major axis by the pretightning force of elastic compression piece
Between circle, the axial gap of brake seat is not only eliminated, plays a part of preventing brake seat axial float, embodies this system
The characteristics of device seat axially position is reliable is moved, and axis hole and major axis caused by the mismachining tolerance of its axis hole of brake seat can be made up
The shaft shoulder produces alignment error.
In use, even if the splined hole rust of brake seat is died from the pattern chain section of major axis under field rainy day occasion, major axis turns
When dynamic, brake is remained to friction plate friction transmission torque thereon.
【Brief description of the drawings】
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
【Embodiment】
Refer to shown in Fig. 1, a kind of attachment structure of Lever Blocks brake and major axis, including be installed on major axis 1
Brake seat 2, inner attrition piece 23, ratchet 22 and outside friction disc 21 are set with successively on brake seat 2, its improvement is：
The circumferentially connecting of brake seat 2 on major axis 1, and brake seat 2 its axis hole left end face against the shaft shoulder 10 in this major axis 1
On, brake seat 2 is provided with elastic pressed piece K in the counterbore 20 that its its right end face is opened up, and elastic pressed piece K both compresses this
Counterbore 20, is resisted against at the axial back-up ring C being installed on major axis 1 again.
Brake hoop 3, commutation ratchet 4, handwheel 5 and self-locking nut 6 are also sequentially installed with major axis 1, wherein, commutate ratchet 4
It is screwed in by multiple thread on major axis 1；The empty set of brake hoop 3 is on major axis 1, left end face and the outside friction disc 21 of brake hoop 3
It is corresponding, and the right-hand end of brake hoop 3 is fixed on commutation ratchet 4；The circumferentially connecting of handwheel 5 is on major axis 1, and handwheel 5 its axle
The left side in hole is against on the shaft shoulder 11 of this major axis 1, and the right side of its axis hole of handwheel 5 is fixedly connected on by self-locking nut 6
The end of major axis 1.
When it is implemented, the right-hand end of brake hoop 3 is fixed on commutation ratchet 4 by elastic spring 7.
The axis hole of brake seat 2 is splined hole, and brake seat 2 is corresponding outer in major axis 1 by its splined hole circumferentially connecting
On spline segment 1a.
The elastic pressed piece of the present embodiment is disk spring.
