Abstract
The invention discloses a bearing clearance adjustment device for a rail wagon bogie. The bearing clearance adjustment device is characterized by comprising a first hook claw, a second hook claw, a first stop block, a second stop block, an adjustment pad, a bolt, a gasket and a nut, wherein the first stop block is welded with the first hook claw; the second stop block is welded with the second hook claw; the first hook claw and the second hook claw are hooked under two ends of a bearing saddle respectively; the first stop block and the second stop block are connected with each other through the bolt, the gasket and the nut in a locking manner; and the adjustment pad is arranged among the first and the second stop blocks and the bearing saddle. Under the condition that any side effect to the bearing saddle is avoided or any manufacturing difficulty is prevented, the clearance adjustment device is seamlessly and fixedly connected with the bearing saddle; furthermore, a bearing clearance can be precisely controlled by changing the specification and the number of the adjustment pad; and the precision is up to 1 millimeter.
Description
Technical field
The present invention relates to the setting device in a kind of railway goods train bogie bearing and adapter gap.
Background technology
The bearing of the railway goods train bogie of employing primary suspension is positioned at the saddle face shoulder block of adapter, saddle face shoulder block generally only has 10mm ~ 15mm high, the vehicle bearing while running into the lifting of unconventional high vibration or vehicle that is in operation can be deviate from saddle face, and vehicle is caused to potential safety hazard.The structure that prior art adopted on adapter and hole, was equipped with bearing space adjustment cushion block and binding bolt stops bearing to be deviate from saddle face.In the mobile range of restriction bearing, for preventing not damaging bearing when normally using, therefore conventionally need to give the certain headspace of bearing, must control the gap between bearing and adapter, under the prerequisite of not damaging bearing, guarantee that bearing do not deviate from saddle face.But adapter belongs to crucial load bearing component, boring can produce harmful effect to itself intensity, and can only adopt black skin location during boring, easily bores tiltedly, is unfavorable for that assembly clearance adjusts cushion block.
Summary of the invention
Technical matters to be solved by this invention is for overcoming above-mentioned technological deficiency, and the setting device in a kind of railway goods train bogie bearing and adapter gap is provided.
For solving the problems of the technologies described above, the present invention proposes the setting device in a kind of railway goods train bogie bearing and adapter gap, it is characterized in that, comprise the first hook pawl, second hooks pawl, the first block, the second block, adjust pad, bolt, packing ring and nut, described the first block and first hooks pawl welding, and the second block and second hooks pawl welding, described first hooks pawl, second hooks below the two ends that pawl is hooked on respectively described adapter, and described bolt, packing ring and nut lock described the first block to be connected with the second block; Described adjustment pad is arranged between described first and second block and described adapter.
As improvement project, described first hooks pawl, second hooks pawl and is respectively equipped with inclined-plane, this two inclined-plane respectively with two end in contact of described adapter.When black nut is fastening, can make setting device and adapter two ends closely connected, guarantee that setting device failure-free is fastened on adapter.
As further improved plan, the upper surface that described first, second block approaches bearing surface is separately respectively the arc surface similar in appearance to bearing surface.Bogie truck in lifting or operational process while there is unconventional vibration, due between first and second block and bearing surface for circle of similitude cambered surface contacts, reduce impulse force suffered on bearing unit area.
In such scheme, described adjustment pad has different thickness specifications, for finely tuning the gap between bearing gap regulator and bearing.
Pass through clamp nut, the gap between bearing gap regulator and adapter can be eliminated in first and second inclined-plane that hooks pawl, lash adjusting device is tightened together with adapter failure-free, at needs, accurately control between bearing and adapter in gap, can use the adjustment pad of different-thickness specification to adjust.
The present invention realizes lash adjusting device in the situation that guaranteeing adapter do not produce any harmful effect or increase any manufacture difficulty and adapter gapless is fastenedly connected, and specification and the quantity that can adjust backing plate by change accurately control bearing space, and its precision can reach 1mm.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is further described in detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is plan structure figure of the present invention.
Fig. 3 is left TV structure figure of the present invention.
The specific embodiment
Shown in Fig. 1, Fig. 2, first hooks pawl 1 and the first block 2 welding, and the second block 5 and second hooks pawl 8 welding; On first and second block 2,5, establish respectively hole, bolt 3 passes through from this hole, and bolt 3, packing ring 6 and nut 7 are connected the first block 2 with the second block 5 lockings.The left side of the first block 2 is provided with a square groove, and 3, bolt is positioned at this square groove, for rotating between locking bolt 3 and nut 7.Adjusting pad 4 is arranged between first and second block 2,5 and adapter 9.
First hooks pawl 1, second hooks pawl 8 and is respectively equipped with inclined-plane 10, this two inclined-plane respectively with two end in contact of adapter 9, the first hook pawl 1, second is hooked below the two ends that pawl 8 is hooked on respectively adapter 9.During clamp nut 7, can make this setting device closely connected with the two ends of adapter 9, guarantee that setting device failure-free is fastened on adapter 9.
As shown in Figure 3, the upper surface that first, second block 2,5 approaches bearing surface 11 is separately respectively the arc surface 13,12 similar in appearance to bearing surface.Bogie truck in lifting or operational process while there is unconventional vibration, due between first and second block 2,5 and bearing surface for circle of similitude cambered surface contacts, reduce impulse force suffered on bearing unit area.
Adjust pad 4 and there is different thickness specifications, adopt the adjustment pad 4 of different-thickness specification, can finely tune the gap between bearing gap regulator and bearing.
It should be noted last that, the above specific embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
