Detailed Description
Example 1
A locking sleeve for eliminating the reaction force of a gasket comprises a sleeve body 1 and a gear ring 2.
The square hole of the square rotating head 20 of the wrench 21 (hydraulic wrench, this is a known device) is correspondingly blocked with the square rotating head 20 of the wrench 21.
A nut sleeve 6 (in a cylindrical shape) is arranged in the sleeve body 1.
The rear end of the nut sleeve 6 corresponds to the position of a sleeve rear boss 15 in the sleeve body 1.
The nut socket 6 has a nut socket front end hole 8 for retaining a nut 9 (hexagonal nut).
A plurality of sleeve tooth grooves 10 are formed in the inner side of the front end of the sleeve body 1, and the sleeve tooth grooves 10 are formed in the axial direction of the sleeve body 1.
The sleeve tooth groove 10 is correspondingly clamped with the gear ring external spline 11 of the gear ring 2.
The rear end surface of the gear ring 2 corresponds to the position of a sleeve front boss 14 in the sleeve body 1.
The number of the sleeve tooth grooves 10 and the number of the gear ring external splines 11 are equal, and the length of each sleeve tooth groove 10 on the circumference is longer than that of the corresponding gear ring external spline 11.
The gear ring 2 is also provided with a gear ring internal spline 12 arranged along the axial direction of the sleeve body 1.
Ring gear internal splines 12 correspond to external splines of external washer 13-2 of washer 13.
The using method comprises the following steps:
after the sleeve rear spline 3 is sleeved on the wrench external spline 4, the sleeve rear spline is tightly fixed by a jackscrew 5, namely the sleeve body 1 and the wrench 21 are fixed together.
The square rotating head 20 of the spanner 21 is correspondingly clamped with the rear end hole 7 of the nut socket.
The gear ring 2 is clamped in the sleeve tooth groove 10.
The washer 13 and the nut 9 are preliminarily screwed onto the circumferential screw 18 fixedly connecting the first flange 16 and the second flange 17.
A back cap 19 is provided on the threaded rod 18 outside the first flange 16.
Since the position of the external spline of the external washer 13-2 of the washer 13 preliminarily screwed on the screw 18 in advance is not necessarily aligned with the internal spline 12 of the ring gear in the process of nesting the washer 13, the length of the sleeve spline 10 on the circumference is set to be longer than that of the corresponding external spline 11 of the ring gear, so that the ring gear 2 can have a rotating space within a certain range in the sleeve body 1 and can be rotationally aligned with the external spline of the washer 13, and the ring gear 2 nests the washer 13.
The position of the boss 15 at the rear of the sleeve corresponds to the position of the outer gasket 13-2.
The gear ring 2 and the sleeve body 1 are sleeved with the washer 13 and the nut 9 forwards together, the rotating head 20 of the wrench 21 drives the nut sleeve 6 to rotate, and the hexagonal nut sleeve 6 is sleeved with the nut 9 to rotate.
The washer 13 is a tightening washer assembly of patent No. 201720996623.8.
The inner washer 3 is the inner washer 13-1 shown in this patent application, facing the rear nut 9.
The outer washer 1 is an outer washer 13-2 shown in this patent application and is clamped in the ring gear 2.
Wherein the teeth 9 are external splines of a washer 13 in this patent application.
The nut 9 compresses the entire rear end surface of the inner washer 13-1, and the inner washer 13-1 rotates following the nut 9.
The outer washer 13-2 is clamped in the gear ring 2, the gear ring 2 is clamped in the sleeve body 1 and does not rotate along with the nut 9, so that the screw 18, the washer 13, the nut 9, the gear ring 2, the nut sleeve 6, the sleeve body 1 and the rotating head 20 are coaxial in the whole locking process, and the washer 13 has no reaction force on the nut 9 and the screw 18.
The inner washer 13-1 and the outer washer 13-2 are clamped together through a clamp spring.
Or on other workpieces requiring a locking nut.
Example 2
Example 2 is substantially the same as example 1 except that:
a waist-shaped hole 22 (through hole) is formed in the circumference of the position of a sleeve tooth groove 10 of the sleeve body 1, a handle 23 is arranged on the gear ring external spline 11 and extends out of the waist-shaped hole 22, and the handle 23 can be manually pulled to assist in the alignment process in the process that the gear ring internal spline 12 and the external spline of the gasket 13 are aligned and sleeved, so that the mechanical friction of parts is reduced.
The length of the waist-shaped hole 22 is set at the position of the handle 23, so that in the locking process, the edge of the external spline 11 of the gear ring is pressed against the edge of the sleeve tooth groove 10 to be stressed, but the handle 23 is not pressed against the waist-shaped hole 22 to be stressed, the handle 23 is easy to damage, and the stress capacity is small.
The device can be used for locking large-scale equipment flange screws in the petroleum industry, and no reaction force is generated in the locking process, for example, the screw 18 is M20-M56, and the thickness of the gasket 3 can reach 12-16 mm.
