Abstract
The utility model relates to an assembly-type wheel body which comprises a wheel axle (1), a wheel sleeve (2) used for walking on a track, and screws (3), wherein the outer side of the wheel axle (1) is a cylindrical surface; screw holes (8) are respectively and evenly distributed at the two sides of the cylindrical surface; the wheel sleeve (2) consists of at least two wheel boot flaps (4); the inner side of the combined wheel sleeve (2) is an internal cylindrical surface matched with the cylindrical surface; the wheel boot flaps (4) are enclosed on the cylindrical surface of the wheel axle (1); stepped holes (9) are respectively formed at the two sides of the wheel sleeve (2), and the number and positions of the stepped holes (9) correspond to those of the screw holes (8); the wheel boot flaps (4) are firmly fixed on the wheel axle (1) by virtue of the screws (3) which pass through the stepped holes (9), so that the wheel sleeve (2) forms a circular ring shape. When the assembly-type wheel body is replaced, a car body is not needed to be lifted, so that the replacement difficulty and the dangerousness are reduced, and the time used for replacement can be shortened.
Description
Technical field
The utility model belongs to wheel technical field, is specifically related to a kind of assembly type wheel body.
Background technology
At present, on many heavy waress and moving-member thereof, all adopt steel wheel, as hoisting crane, on the driving of workshop lifting use and train, all use steel wheel, and these steel wheels are in the annual enormous amount of producing of China, wherein take turns the larger wheel in footpath and be mostly to adopt cast steel casting at present, though through heat treatment, but resistance to abrasion is poor, in use, wheel wearing and tearing are very fast, therefore these wheels used after a period of time, more wheel change, very difficult things and change these steel wheels, no matter be to change skyborne vehicle wheel, still change ground train wheel, first after needing heavy car body to lift, more wheel change, very effort and dangerous, once also having another important reason is exactly to change whole wheel all must to be changed, and not only waste metallic material, and it is also very expensive to change the expense causing.
Summary of the invention
Technical problem to be solved in the utility model is to change trouble for existing steel wheel, the problem wasting time and energy when replacing, and a kind of assembly type wheel body is provided.When this wheel is changed, only need to change the wheel boots lobe damaging, remaining part does not need to change, and because wheel boots are many lobes compound types, does not need to lift heavy car body when replacing.
The technical solution adopted in the utility model: a kind of assembly type wheel body, it comprises wheel shaft 1, for the wheel case 2 of walking in orbit, screw 3, wheel shaft 1 outside is the face of cylinder, both sides, the described face of cylinder are provided with screw hole 8 in uniform way, wheel case 2 is made up of at least two wheel boots lobes 4, the inner side of the wheel case 2 being combined into is the inner cylinder face matching with the described face of cylinder, wheel boots lobe 4 is enclosed on the face of cylinder of wheel shaft 1, the both sides of wheel case 2 are provided with the stepped hole 9 corresponding with screw hole 8 quantity and position, and wheel boots lobe 4 is fastened on wheel shaft 1 through stepped hole 9 by screw 3, make wheel case 2 form an annular arrangement.
Further, the arranged outside rail groove 5 of the wheel boots lobe 4 of composition wheel case 2, at least one side is provided with rib 6.
Further, the outside of the wheel boots lobe 4 of composition wheel case 2 is cylindrical surface 7.
The utility model compared with prior art its beneficial effect is: the utility model is simple in structure, cost is low, long service life; Wheel body can be with lower-cost cast iron manufacture, and can use for a long time, and wheel boots can be with the good material manufacture of resistance to abrasion, less because of material consumption, cost is lower, can life-saving, when replacing, do not need to lift car body, reduce and change difficulty and danger, reduce and change the used time.

Detailed description of the invention
embodiment 1
As shown in Figure 3, a kind of assembly type wheel body, it comprises wheel shaft 1, wheel case 2, screw 3, the hollow structure of using for bearing is installed in wheel shaft 1, wheel shaft 1 outside is the face of cylinder, wheel shaft 1 both sides are provided with respectively 6 screw holes 8 fifty-fifty, wheel case 2 is made up of 3 wheel boots lobes 4, each 1/3rd of boots lobe 4 whole wheel cases of taking turns, the arranged outside of described wheel case 2 is useful on the rail groove 5 of walking in orbit, wheel boots lobe 4 both sides are provided with rib 6, on the rib 6 of wheel boots lobe 4 each side, be provided with 2 positions stepped hole 9 corresponding with screw hole 8 distributing positions, the inner side of the wheel case 2 being combined into is the inner cylinder face matching with the described face of cylinder, 3 wheel boots lobes 4 are enclosed on the face of cylinder of wheel shaft 1, and 3 wheel boots lobes 4 are fastened on wheel shaft 1 through described stepped hole 9 by 12 screws 3, make wheel case 2 form an annular arrangement.
embodiment 2
As shown in Figure 4, a kind of assembly type wheel body, it comprises wheel shaft 1, wheel case 2, screw 3, the hollow structure of using for bearing is installed in wheel shaft 1, wheel shaft 1 outside is the face of cylinder, wheel shaft 1 both sides are respectively arranged with 8 screw holes 8, wheel case 2 is made up of 4 wheel boots lobes 4, each 1/4th of boots lobe 4 whole wheel cases of taking turns, described arranged outside of taking turns boots lobe 4 is useful on the rail groove 5 of walking in orbit, one side of wheel boots lobe 4 is provided with rib 6, both sides at wheel boots lobe 4 are provided with respectively 2 positions stepped hole 9 corresponding with screw hole 8 distributing positions fifty-fifty, the inner side of the wheel case 2 being combined into is the inner cylinder face matching with the described face of cylinder, 4 wheel boots lobes 4 are enclosed on the face of cylinder of wheel shaft 1, and 4 wheel boots lobes 4 are fastened on wheel shaft 1 through described stepped hole 9 by 16 screws 3, make wheel case 2 form an annular arrangement.
embodiment 3
