Abstract
The utility model relates to a kind of bulldozer riding wheel structure, comprise stepped shaft, wheel body, bearing, support roller lid, described bearing be arranged on stepped shaft end and between stepped shaft and wheel body, support roller lid is fixed on wheel body outer end, the end of described stepped shaft is also fixed with circular jam plate, described jam plate is secured by bolts on axle outer end, and the radius of described jam plate is greater than the inside radius of bearing inner ring, and the radius of described jam plate is not more than the outside radius of bearing inner ring.The beneficial effects of the utility model are compared with existing support roller: the utility model supporting-roller shaft is shorter than existing supporting-roller shaft, and do not need processing excircles end-face helical, and jam plate cost and manufacturing procedure are less than lock nut, so easy for installation, efficiency is high, and cost is low.
Description
technical field:
The utility model relates to a kind of bulldozer riding wheel structure.
background technology:
The axial location of the wheel holding mechanism that current domestic continuously tracked vehicle uses is all lock nut locking mechanism, exactly supporting-roller shaft and lock nut are fixed by screw thread, adding middle fluting, snap ring is stuck in the double locking version on supporting-roller shaft and lock nut, although this structure is stablized, but operation is various, cost is high, processing, assembling difficulty, dimension chain is loaded down with trivial details.First, the length of supporting-roller shaft increasing by one section and carrys out machining screw, and supporting-roller shaft and lock nut process the groove fixing snap ring, grasping the position of two grooves in location when assembling, space is little, snap ring assembling difficulty, and lock nut is complex-shaped, manufacturing procedure is many, and efficiency is low, and holistic cost is high.
summary of the invention:
The purpose of this utility model is to provide a kind of bulldozer riding wheel structure, solves the manufacturing procedure existed many, assembling difficulty, the problems such as efficiency is low, and holistic cost is high.
The utility model is achieved by the following technical solution, a kind of bulldozer riding wheel structure, comprise stepped shaft, wheel body, bearing, support roller lid, described bearing be arranged on stepped shaft end and between stepped shaft and wheel body, support roller lid is fixed on wheel body outer end, and the end of described stepped shaft is also fixed with circular jam plate, and described jam plate is secured by bolts on axle outer end, the radius of described jam plate is greater than the inside radius of bearing inner ring, and the radius of described jam plate is not more than the outside radius of bearing inner ring.
Further improvement of the utility model also has, and above-mentioned jam plate is provided with through hole, and described stepped shaft end is provided with axial tapped bore.
Further improvement of the utility model also has, and the quantity of above-mentioned bolt is 2-4.
Further improvement of the utility model also has, and above-mentioned bolt is uniform in the plane in jam plate institute.
Further improvement of the utility model also has, and above-mentioned support roller lid of stating is fixedly connected with described wheel body by bolt.
The beneficial effects of the utility model are: supporting-roller shaft of the present utility model adopts stepped shaft and is shorter than existing supporting-roller shaft, and does not need processing excircles end-face helical, and jam plate cost and manufacturing procedure are less than lock nut, so easy for installation, efficiency is high, and cost is low.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
1-stepped shaft, 2-jam plate, 3-bolt, 4-support roller lid, 5-wheel body, 6-bearing.
detailed description of the invention:
Referring now to accompanying drawing, the feature of the utility model structure is described.
The utility model riding wheel structure (Fig. 1), a kind of bulldozer riding wheel structure, comprise stepped shaft 1, wheel body 5, bearing 6, support roller lid 4, described bearing 6 be arranged on stepped shaft 1 end and between stepped shaft 1 and wheel body 5, support roller lid 4 is secured by bolts in wheel body 5 outer end, the end of described stepped shaft is also fixed with circular jam plate 2, described jam plate 2 is fixed on axle outer end by bolt 3, the radius of described jam plate is greater than the inside radius of bearing inner ring, and the radius of described jam plate is not more than the outside radius of bearing inner ring.Jam plate 2 is provided with through hole, and described stepped shaft 1 end is provided with axial tapped bore.The quantity of bolt 3 is 2-4, and bolt 3 is uniform in the plane in jam plate 2 institute.
