Abstract
The utility model discloses one and turn to the axial locking device of idle rod bearing, comprise support body, rotating shaft, screw collar, described rotating shaft is located in support body, screw thread fit is passed through between described screw collar and support body end, between described support body and screw collar, binding site is provided with knock hole, is provided with bearing pin in described knock hole.Can prevent from using rear thread to overlap for a long time to loosen, avoid the fault occurring steering swivel system looseness, abnormal sound, largely, improve reliability and the service life of idle rod bearing.
Description
Technical field
The utility model relates to steering swivel system technical field, especially relates to one and turns to the axial locking device of idle rod bearing.
Background technology
Idle rod bearing is as the driving device of automobile steering system (use circulating ball steering box), and it provides support for idle rod, and the quality of its performance directly has influence on operation comfort and the safety of driver.
Idle rod bearing in current automobile steering system (using circulating ball steering box), its be generally axially with between screw collar and support body with directly to compress after being threaded or the coated thread glue that locks carries out locking on screw thread, these two kinds of mode structures are simple, but directly with being threaded, long-time use rear thread will loosen, cause endplay excessive, occur the problems such as steering swivel system looseness, abnormal sound; And coated thread locking glue on screw thread, it not easily adjusts the rotating torque of bearing rotating shaft when general assembly, and the process that there is relaxing serializability finite sum coating locking glue such as not easily to monitor at the problem.
Utility model content
Not enough for prior art, technical problem to be solved in the utility model is to provide one and turns to the axial locking device of idle rod bearing, to reach the long-time object using rear thread cover not easily to loosen.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
This turns to the axial locking device of idle rod bearing, comprise support body, rotating shaft, screw collar, described rotating shaft is located in support body, screw thread fit is passed through between described screw collar and support body end, between described support body and screw collar, binding site is provided with knock hole, is provided with bearing pin in described knock hole.
Described knock hole threadingly overlaps axial setting.
Interference fit between described knock hole and bearing pin.
Spring perch and belleville spring is provided with between the inherent rotating shaft of described support body and screw collar.
Be provided with half knock hole inside described support body, outside screw collar, be provided with second half knock hole.
The utility model compared with prior art, has the following advantages:
Punch between the screw collar of idle rod bearing and support body and add bearing pin very failure-free be connected and fixed, prevent from using for a long time rear thread to overlap and loosen, avoid the fault occurring steering swivel system looseness, abnormal sound; Simultaneously under the effect of belleville spring, auto-compensation rotates the gap of wearing and tearing generation mutually due to rotating shaft and spring perch, improves reliability and the service life of idle rod bearing largely.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this specification sheets and the mark in figure are briefly described:
Fig. 1 is the utility model locking device structural representation.
Fig. 2 is the utility model bearing pin schematic diagram.
In figure: 1. bearing pin, 2. screw collar, 3. belleville spring, 4. spring perch, 5. rotating shaft, 6. support body.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail.
As depicted in figs. 1 and 2, this turns to the axial locking device of idle rod bearing, comprise bearing pin 1, screw collar 2, belleville spring 3, spring perch 4, rotating shaft 5, support body 6, wherein, rotating shaft 5 is located in support body 6, and pass through screw thread fit outside screw collar 2 and between support body 6 tip inside, between support body 6 and screw collar 2, binding site is provided with knock hole, bearing pin 1 interference fit is located in knock hole, is provided with spring perch 4 and belleville spring 3 between the inherent rotating shaft 5 of support body 6 and screw collar 2.
After rotating shaft 5 loads and fills up the support body 6 of lithium base grease, load spring perch 4 and belleville spring 3 successively, should be noted that quantity and direction, then screw collar 2 by being threaded in support body 6.Special tooling adjusts the screw-down torque of screw collar 2, and checks the rotating torque of rotating shaft 5, when rotating torque reaches scope of design requirement, stop the screw-down torque adjustment of screw collar 2; Be screwed position at screw collar 2 and support body 6 axially punch and add bearing pin 1, due to the existence of bearing pin 1, can screw collar 2 and support body 6 very failure-free link together.
Be provided with half knock hole inside support body 6, be provided with second half knock hole outside screw collar 2, between bearing pin 1 and knock hole, interference fit is fixed together, and is provided with solid glue between bearing pin 1 and knock hole, prevents bearing pin from departing from knock hole, improves fixing reliability.
Assembled rear detection axis of rotation moment and rotating shaft endplay, the tightness screwed in by screw collar 2 realizes the adjustment of axis of rotation moment and endplay, to obtain the rotating torque of designing requirement.
Bearing pin 1 and knock hole are interference fit, screw collar 2 and support body 6 are fixed together by bearing pin 1 firmly, make screw collar can not cause loosening due to the long-time use of idle rod bearing, simultaneously under the effect of belleville spring 3, auto-compensation rotates due to rotating shaft 5 and spring perch 4 gap that wearing and tearing produce mutually, also solves the contradiction that idle rod bearing screw collar screw-down torque and axis of rotation moment can not be balanced.
This locking device structure is simple, is convenient to make, and cost is low; And punch between the screw collar 2 of idle rod bearing and support body 6 and add bearing pin very failure-free be connected and fixed, prevent from using rear thread to overlap for a long time to loosen, thus prevent endplay excessive, avoid the fault occurring steering swivel system looseness, abnormal sound, largely, improve reliability and the service life of idle rod bearing.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present utility model and technical scheme are carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
