Slack adjuster according to an embodiment of the present invention, the slack adjuster are used to adjust the framework and wheel of bogie
Gap between, as shown in Figure 1, comprising: the first rotation section 10 and the second rotation section 20, the first rotation section 10 are used for and steering
The curb girder of the framework of frame connects；Second rotation section 20 is used for wheel to connection, and the second rotation section 20 is retractably installed at first
To adjust framework and take turns the gap between on rotation section 10.
The slack adjuster to apply the technical scheme of the present invention, the slack adjuster are used to adjust the framework of bogie
With gap of the wheel between, pass through the first rotation section 10 of setting and the second rotation section 20, the structure of the first rotation section 10 and bogie
The curb girder of frame connects；With wheel to connection, the second rotation section 20 is retractably installed on the first rotation section 10 for second rotation section 20
Adjusting framework and take turns the gap between, solving bogie frame curb girder in the prior art and taking turns the gap tune between
The problem of whole difficulty influences operating efficiency greatly.
When it is implemented, the first rotation section 10 is rotary sleeve, the second rotation section 20 is support column, the first 10 sets of rotation section
It is located on the second rotation section 20.There is threaded hole 11, the second rotation section 20 has and threaded hole in the axle sleeve of first rotation section 10
11 compatible threaded rods 21, threaded rod 21 are rotationally threaded through in threaded hole 11, thus rotate the first rotation section 10 or
It can make both the first rotation section 10 and the second rotation section 20 are opposite to stretch out or bounce back when the second rotation section 20.
For the ease of the second rotation section 20 of rotation and make the second rotation section 20 and wheel to having bigger contact area, it is optional
Ground is provided with nut portion 22 in the end of threaded rod 21, and the outer end face in nut portion 22, to abutting together, is turned to wheel in adjustment
The curb girder of the framework of frame and when taking turns the gap between, the first rotation section 10 is gripped, rotated using spanner using tool
Nut portion 22 can be such that the second rotation section 20 rotates relative to the first rotation section 10,20 phase of the first rotation section 10 and the second rotation section
It mutually stretchs out, to adjust the curb girder of the framework of bogie and take turns the gap between.
In order to enable the first rotation section 10 more stably to abut with the curb girder of the framework of bogie, optionally, also set up
There is fixing seat 30, fixing seat 30 is rotatably coupled with the first rotation section 10, and fixing seat 30 with curb girder for abutting.
Specifically, thrust ball bearing 40 and deep groove ball bearing 50 are provided in fixing seat 30, fixing seat 30 passes through thrust
Ball bearing 40 and deep groove ball bearing 50 are rotatably coupled with the first rotation section 10.
The first step slot and second step slot being recessed to its inside are provided in fixing seat 30, the card of thrust ball bearing 40 is set
In first step slot, deep groove ball bearing 50 is fastened in second step slot and abuts together with thrust ball bearing 40.Accordingly
Ground, the end of the first rotation section 10 are Step Shaft, and Step Shaft includes First stage and second step section, thrust ball bearing 40
Inner ring was set on the First stage, and the inner ring of deep groove ball bearing 50 is set in second step section to make the first rotation section 10
It can be rotated relative to fixed seat 30, thrust ball bearing 40 plays the axial load born between the first rotation section 10 and fixing seat 30
Effect；Deep groove ball bearing 50 plays the role of bearing the radial load between the first rotation section 10 and fixing seat 30.
When the curb girder surface of the framework of bogie is curved surface, fixing seat 30 is difficult to steadily abut with curb girder, optionally,
It is additionally provided with spare cover for seat 60, is had and the matched card slot of fixing seat 30, spare cover for seat 60 on an end face of spare cover for seat 60
It is set in fixing seat 30 by card slot, another end face of spare cover for seat 60 is curved surface compatible with the surface of curb girder, should
Curved surface forms to be bonded completely with curb girder surface according to the surface shape rasion of different curb girders, guarantees to adjust in gap
It can steadily be abutted together with curb girder in journey.
Slack adjuster according to an embodiment of the present invention includes 6 parts: fixing seat 30, thrust ball bearing 40, zanjon
Ball bearing 50, the first rotation section 10, the second rotation section 20 and spare cover for seat 60.
The effect of fixing seat 30 is support thrust ball bearing 40 and deep groove ball bearing 50；The effect of thrust ball bearing 40 is to hold
By axial thrust loads；The effect of deep groove ball bearing 50 is to bear radial load；First rotation section 10 and the second rotation section 20
Effect is contraction and up-sizing；The effect of spare cover for seat 60 is lateral beam of bogie surface when being curved surface, by fixing seat 30
The upper spare cover for seat 60 of installation, meets application of a surface.
By rotate the second rotation section 20, so that regulating device is met working space requirement, by the surface of fixing seat 30 against
Curb girder surface (surface is plane), the surface of the second rotation section 20 is resisted against wheel to surface, by rotating the second rotation section
20, adjust size.
When lateral beam of bogie surface is curved surface, spare cover for seat 60 (spare cover for seat 60 and curb girder are installed in fixing seat 30
Contact surface is formed according to lateral beam of bogie curved surface rasion, so that the curved surface of spare cover for seat 60 is bonded with the curved surface perfection of curb girder)
Afterwards, spare 60 surface of cover for seat is resisted against curb girder surface (surface is curved surface), and the second rotation section 20 is resisted against wheel to surface, passes through rotation
Turn the second rotation section 20, adjusts size.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
