Abstract
The utility model relates to a steel wheel hub polyurethane trundle, which comprises a wheel hub, an axle sleeve arranged at the center of the wheel hub, and a polyurethane wheel sleeve arranged at the outer side of the wheel hub, the wheel hub is formed by splicing after punching two left and right cold-rolled steel plates, inwardly dished circular reinforced ribs are respectively punched on the two left and right cold-rolled steel plates, grooves are arranged at the both ends of the axle sleeve, a central hole is arranged at the center of the wheel hub, the edge of the central hole is inserted into the groove of the axle sleeve to form the tight fit, and the outer side surface of the polyurethane wheel sleeve is an arc surface. Compared with the prior art, the utility model has the advantages that the self weight is light, the bearing force is large, the rolling is light, the steering is nimble, and the outer appearance is artistic.
Description
Technical field
The utility model relates to a kind of transport trolley caster wheel, relates in particular to a kind of steel wheel hub polyurethane castor.
Background technology
Existing polyurethane castor is divided into two classes, and a class is plastic core outsourcing thermoplastic polyurethane (TPU) wheel, and another kind of is cast iron core outsourcing casting type polyurethane (CPU) wheel.All there is defective separately in this polyurethane castor of two types, and plastic core outsourcing thermoplastic polyurethane castor major defect is: carrying is light, core wheel is insecure, not wear-resisting, allow foreign matters such as the end of a thread, flexible lines twine easily; Cast iron core outsourcing casting type polyurethane castor major defect is: it is plane rather than cambered surface that too heavy and carrying and little (having only a brace rod in the middle of the wheel hub), cast iron waste energy that contaminated environment, wheel wicking surface get rusty easily, wheel contacts with ground, twines easily so boost foreign matters such as heavily turning to dumb, the end of a thread or flexible lines.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of big from heavy and light, carrying, roll light, turn to flexibly, the steel wheel hub polyurethane castor of good looking appearance.
The purpose of this utility model can realize in the following manner: a kind of steel wheel hub polyurethane castor, comprise wheel hub, be located at the axle sleeve at this wheel hub center, be located at the polyurethane wheel cover in this wheel hub outside, it is characterized in that, described wheel hub is by a left side, right two cold-rolling steels are spliced after punching press, a described left side, right two cold-rolling steels respectively punching press the cyclic reinforcing rib of one indent, described axle sleeve two ends respectively are provided with a circle groove, described wheel hub center has a centre hole, the edge of this centre hole inserts in the groove of above-mentioned axle sleeve and forms flush fit, and the lateral surface of described polyurethane wheel cover is an arc surface.
Also comprise fagging, described fagging is located in the wheel hub.
Described fagging is an annular arrangement, its inner rim and the welding of described axle sleeve, its outer rim and described wheel hub welded top.
Described fagging radial punch at least two protruding, spill reinforced ribs that are provided with at interval, the indent cyclic reinforcing rib that this is protruding, the spill reinforced rib holds out against described left and right two cold-rolling steels.
Compared with prior art, the utlity model has following advantage:
1. from heavy and light, have only half of cast-iron wheel weight; Saving in material, free from environmental pollution.
2. carrying is big, is provided with through three block plates such as left and right two cold-rolling steels of flanging and midship mountings to support, and not resembling cast-iron wheel has only middle fagging, and it is not heavily loaded not resemble plastic core yet.
3. wheel contacts with ground and is arc surface, roll light, turn to flexibly.
4. wear-resisting, the outsourcing casting type polyurethane is a network molecular structure, and thermoplastic polyurethane is a linearity molecular structure.
5. shock resistance, appearance are cold-rolling steel, and it is easy to break not resemble plastic core.
6. good looking appearance, the appearance cold-rolling steel is zinc-plated, and smooth being difficult for again gets rusty, and the unfairness of cast iron core appearance can not be zinc-plated, easily gets rusty.
7. antiwind, wheel hub is made with the whole punching press of cold-rolling steel, and soft surplus is difficult for twining.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the front view of the utility model fagging.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of steel wheel hub polyurethane castor, comprise wheel hub 1, be located at the axle sleeve 2 at this wheel hub center, be located at the polyurethane wheel cover 3 in this wheel hub outside, be located at the fagging 4 in this wheel hub, described wheel hub 1 is by a left side, right two cold-rolling steels are spliced after punching press, a described left side, right two cold-rolling steels respectively punching press the cyclic reinforcing rib 11 of one indent, described axle sleeve 2 two ends respectively are provided with a groove 21, described wheel hub center has a centre hole 12, the edge 13 of this centre hole 12 inserts in the groove 21 of above-mentioned axle sleeve and forms flush fit, the lateral surface 31 of described polyurethane wheel cover 3 is an arc surface, described fagging 4 is an annular arrangement, its inner rim and 3 welding of described axle sleeve, its outer rim and described wheel hub 1 welded top, the radial punch of described fagging 4 three convex reinforced ribs 41 and three spill reinforced ribs 42, this is protruding, the spill reinforced rib is provided with at interval, this is protruding, spill reinforced rib 41,42 hold out against a described left side, the indent cyclic reinforcing rib 11 of right two cold-rolling steels reaches by the external force that radially decomposes side direction in order to bear side direction external force.
Claims (4)
1. steel wheel hub polyurethane castor, comprise wheel hub, be located at this wheel hub center axle sleeve, be located at the polyurethane wheel cover in this wheel hub outside, it is characterized in that, described wheel hub is spliced after punching press by left and right two cold-rolling steels, described left and right two cold-rolling steels respectively punching press the cyclic reinforcing rib of one indent, described axle sleeve two ends respectively are provided with a circle groove, described wheel hub center has a centre hole, the edge of this centre hole inserts in the groove of above-mentioned axle sleeve and forms flush fit, and the lateral surface of described polyurethane wheel cover is an arc surface.
