Abstract
The utility model provides another kind of supporting idle wheel structure of a mobile car. With the adoption of the supporting idle wheel structure of the mobile car, the damage of the supporting idle wheel caused by that a bearing is pulled away from a center shaft under the condition of high speed and heavy load of the mobile car, the center shaft is prevented from rotating when the supporting idle wheel is rolled on a lead rail, and the normal work of the mobile car is ensured. The supporting idle wheel structure of the mobile car comprises the center shaft and the supporting idle wheel, wherein the supporting idle wheel is installed on the center shaft through the bearing; the center shaft passes through a car body installing hole and is slidably fitted with the installing hole; the supporting idle wheel is fixed with the bearing through an outer pressing cover; and the end faces of the center shaft and the bearing are positioned through an axial end baffle. The supporting idle wheel structure of the mobile car is characterized in that the bearing is a tapered roller bearing; and two tapered roller bearings are installed at the periphery of the center shaft in opposite direction.
Description
Technical field
The utility model relates to the bracing or strutting arrangement of used travelling car in the seamless steel tube production chain, is specially the support roller structure of travelling car.
Background technology
Used travelling car in seamless steel tube production chain adopts a plurality of support rollers to support the travelling car car body usually, and the support roller that provides support is contained on the guide rail of special setting; And on guide rail, come, return and slide, require support roller be able to rotate freely, could guarantee the normal operation of travelling car; The support roller structure of the travelling car that adopts is at present seen illustrated in figures 1 and 2ly, and the bearing that support roller uses is single deep groove ball bearing 4; Deep groove ball bearing 4 is installed on the axis 2; Roller 3 is installed on the outer ring of deep groove ball bearing 4, and inner ring one side of deep groove ball bearing 4 is equipped with axle head baffle plate 6 on the axis 2, and roller 3 one sides that contact with the outer ring of deep groove ball bearing 4 are equipped with end cap 5; Be used for the fixing of deep groove ball bearing 4; The other end that contacts with deep groove ball bearing 4 inner rings on the axis 2 is the shaft shoulder, is used for the axial location of deep groove ball bearing 4, and prevents that the roller 3 that rotates from contacting the generation friction with the side plate of dolly car body; Axis 2 matches with dolly car body mounting hole; Make the load capacity on the car body pass to roller 3 through axis 2; Axle head gland 1 is equipped with in the other end of axis 2, and axle head gland 1 is fixed on axis 2 end faces through tie bolt 7, prevents that axis 2 from skidding off from dolly car body mounting hole.Its shortcoming is: this structure adopts single deep groove ball bearing, because it can not bear bigger axial load, under travelling car high speed, heavily stressed situation, single deep groove ball bearing damages easily; Single deep groove ball bearing is fixed through binding bolt by the axle head baffle plate, under travelling car high speed, heavily stressed situation, causes bolt looseness and fracture easily, causes single deep groove ball bearing to deviate from axis, and support roller damages; And support roller rolls on guide rail and be prone to drive axis and rotate, and causes the binding bolt of end gland of axis loosening or come off, and causes support roller from travelling car car body mounting hole, to skid off, and influence the travelling car normal operation, occurs equipment breakdown in the time of seriously.
Summary of the invention
There is above-mentioned defective to prior art; The utility model provides the support roller structure of another kind of travelling car; Can avoid under travelling car high speed, heavily stressed situation; Bearing is deviate from the problem that axis causes support roller to damage, and can prevent the rotation of axis when support roller rolls on guide rail, guarantees the normal operation of travelling car.
Its technical scheme is such; It comprises axis, support roller; Said support roller through bearing installation on said axis, said axis pass dolly car body mounting hole and with said mounting hole bearing fit, said support roller and said bearing pass through outside gland stationary positioned; Said axis and said bearing carry out the end face location through the axle head baffle plate; It is characterized in that: described bearing is a tapered roller bearing, and said tapered roller bearing is provided with two, and said two tapered roller bearing subtends are installed on said axis periphery.
It is further characterized in that: said axle head baffle plate and said axis are made integral body; On said axis, between said dolly car body and the said tapered roller bearing spacer ring is installed; External side end at said axis is provided with draw-in groove, and clamp is installed in the said draw-in groove, and said clamp and said dolly car body are fixed through binding bolt, and said clamp is provided with two.
The utility model adopts after the said structure, and two tapered roller bearing subtends are installed on the axis, can bear bigger axial load; Under travelling car high speed, heavily stressed situation, tapered roller bearing is not fragile, and bearing baffle and axis are made an integral body; Can prevent that tapered roller bearing from deviating from axis and causing support roller to damage under the service condition of dolly high-speed overload; When support roller rolled on guide rail, because the rotation that axis stops axis is blocked in the effect of clamp, clamp was fixed on the travelling car car body; Can also prevent that axis from skidding off from travelling car car body mounting hole, guarantee the normal operation of travelling car.
