Abstract
The utility model relates to a bearing clearance measuring device, which belongs to the technical field of detecting apparatuses. The bearing clearance measuring device is mainly formed by a spindle head permanent seat, a bearing mounting seat, a lever and a steadying bar, wherein the spindle head permanent seat extends out of the spindle head; the bearing mounting seat is provided with a stepped hole through which the spindle head can pass; pins extend out of two sides of the bearing mounting seat; the large diameter part of the stepped hole is fixedly joined with the spindle head permanent seat by a bearing, and the end surface of the spindle head permanent seat fixedly presses a press plate of the bearing; a fork port capable of clamping the pin is formed at one end of the lever, a torque spanner is formed at the other end of the lever, and the middle part of the lever is hinged with the steadying bar. The bearing clearance measuring device has simple structure, is easy to manufacture and convenient to use, and can accurately measure the axial clearance of the bearing after being assembled.
Description
Technical field
The utility model relates to a kind of measurement mechanism, and especially a kind of bearing clearance measurement mechanism belongs to the appliance technical field.
Background technology
Taper roll bearing is the rotatably supported vital part of rail truck reduction gear box, and the quality of its assembly quality directly has influence on the operational situation and the life-span of speed reduction unit, and even the normal operation of speed reduction unit.
Speed reduction unit temperature in operation process can rise, owing to expand with heat and contract with cold, the end play of bearing will change within the specific limits.This just need reserve rational gap when bearing assembles.The too big operation in gap is not steady, may make stuck, scaling loss during bearing operation too for a short time.Therefore, the measurement in bearing installation time crack just seems particularly important.
At present, the taper roll bearing that existing rail truck reduction gear box supports usefulness does not still have special-purpose measurement mechanism, and assembling is difficult to preset clearance is controlled in the reasonable range mainly by rule of thumb.
The utility model content
The purpose of this utility model is: at the problem that above-mentioned prior art exists, proposes a kind ofly can make things convenient for exactly that measurement axis takes up the bearing clearance measurement mechanism of joining axial gap, back.
In order to reach above purpose, bearing clearance measurement mechanism of the present utility model mainly is made of spindle nose holder, Bearing Installation seat, lever and support bar; Described spindle nose holder extends spindle nose; Described Bearing Installation seat is shaped on the stepped hole that can install spindle nose, and pin is extended in both sides; The place, big footpath of described stepped hole is connected with the spindle nose holder by bearing, and end face is the pressing plate of pressure holding bearing fixedly; One end of described lever forms the prong that can block pin, and the other end forms dial torque wrench, and middle part and described support bar are hinged.
During measurement, with the spindle nose holder be equipped with measured bearing the axle be connected, clock gauge and so on survey instrument is fixed on correct position after, gauge outfit is resisted against the spindle nose end face.Then, live the lever that prong blocks Bearing Installation seat pin nail by they sup-port.When holding the spindle nose holder, pull the dial torque wrench of lever end, the spindle nose holder is delivered to axial force on the measured bearing, on gauge outfit, demonstrate the end play of measured bearing.
This shows that bearing clearance measurement mechanism of the present utility model is simple in structure, easy to manufacture, easy to use, the end play after measurement axis takes up and joins exactly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the perspective view of an embodiment of the utility model.
Fig. 2 is the planar structure synoptic diagram of Fig. 1 embodiment.
Embodiment
Embodiment one
Present embodiment is a kind of bearing clearance measurement mechanism of rail truck reduction gear box support with taper roll bearing that be used to measure, as shown in Figure 1, 2.Each part sequence number is among the figure: pressing plate 1, screw 2, clock gauge 3, nut 4, Bearing Installation seat 5, lever 6, support bar 7, dial torque wrench 8, supporting pin 9, spindle nose holder 10, turning handle 11, bearing 12, bearing inner race clamping sleeve 13.
The main body of spindle nose holder 10 is in the form of annular discs, and disc centre is extended spindle nose, and a side of disk is fixed with turning handle 11.
5 one-tenth of Bearing Installation seats are circular, and the center is shaped on the stepped hole that can install spindle nose, and pin is radially extended in the cylindrical both sides.The place, big footpath of stepped hole matches with the external diameter of bearing 12, and the internal diameter of bearing 12 and the external diameter of spindle nose match, so the big footpath of stepped hole passes through bearing 12 and be connected with the spindle nose of spindle nose holder 10, can relatively rotate mutually.The bigger diameter end face of stepped hole is by the fixing pressing plate 1 of pressure holding bearing 12 outer rings of screw 2.The inner ring of bearing is compressed by bearing inner race clamping sleeve 13 by nut 4.
During use, spindle nose holder 10 is connected with the reducer gear axle that the measured circle taper roller bearing is housed.The gauge stand of clock gauge 3 is fixed on nearby correct position, and gauge outfit is pressed on the spindle nose end face of spindle nose holder 10.The bolt that passes support bar 7 is screwed in the threaded hole of measured bearing lid fixing, lever 6 just can be about supporting pin 9 be the center rotation.Because the prong of lever 6 inserts in the pin of Bearing Installation seat 5, when therefore direction of present dynasty applies moment to dial torque wrench 8, by lever 6 effects, can there be 10 pairs of gear shafts of spindle nose holder to produce axial force, this moment, clock gauge 3 meetings showed the reading that produces because of measured bearing end play, move dial torque wrench 8 more in the opposite direction after writing down this reading, clock gauge 3 will show another reading, and the difference of trying to achieve twice reading is the play parameter of measured circle taper roller bearing.In the operation, can hold spindle nose holder 10 by turning handle 11.
The utility model is not limited to be used in measurement rail truck reduction gear box and supports the bearing clearance of using taper roll bearing.In addition to the implementation, other embodiments can also be arranged.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
