Detailed Description

The following description of a preferred embodiment of the present invention will be made in conjunction with the accompanying drawings.

Referring to fig. 1 to 2, the high load caster provided by the present invention includes a caster body 1 and a bearing 2 disposed in the caster body 1, wherein two axial ends of the bearing 2 are respectively and fixedly mounted with a reinforcing cover 3 to form a reinforcing bearing; the wheel body 1 is coated on the peripheral surface of the reinforced bearing.

The bearing 2 comprises an outer ring, an inner ring and balls between the inner ring and the outer ring. Strengthen the inside wall of lid 3 and the outer lane wall interference fit of bearing 2, under the exogenic action, will strengthen lid 3 lid and fit on bearing 2.

Or, the outer side wall of the outer ring of the bearing 2 is provided with an annular groove 201 perpendicular to the axis thereof, and the inner side wall of the reinforcing cover 3 is provided with an annular bulge 301 corresponding to the annular groove 201; the annular protrusion 301 of the reinforcing cover 3 is clamped in the annular groove 201 of the bearing 2, so that the reinforcing cover 3 and the bearing 2 are tightly matched. With the same structure, an annular protrusion can be arranged on the side wall of the outer ring of the bearing 2, and an annular groove is arranged on the reinforcing cover 3.

Wherein the end surface of the reinforcing cover 3 extends along the radial center thereof and covers at least the outer wall of the inner ring of the bearing 2, so that a closed space is formed between the inner ring and the outer ring of the bearing 2. Of course, the reinforcing cover 3 may be other planar or three-dimensional shapes capable of increasing the bearing force area. Preferably, the utility model discloses a strengthen lid 3 and choose annular structure for use.

Simultaneously, strengthen the lateral wall and the terminal surface of lid 3 and have certain thickness, make the lifting surface who strengthens the bearing include the outer lane of bearing 2, strengthen the lateral wall of lid 3 to and strengthen the thickness face of the lateral wall of lid 3, need not change the specification of bearing 2 promptly and can improve the lifting surface of bearing 2, thereby promote the ability that bearing 2 bore load, can prolong the life of truckle simultaneously.

Wheel body 1 is integrated into one piece, and wheel body 1 is through the injection molding process cladding on the outer peripheral face of strengthening the bearing, strengthens the bearing promptly as the embedding piece, packs into the grinding apparatus chamber of injection molding machine in advance, then the injection molding machine makes wheel body 1 shaping and cladding on the outer peripheral face of strengthening the bearing through the extrusion injection molding, makes the outer peripheral face of strengthening the bearing fixed and become an organic whole with wheel body 1 by the cladding, obtains the utility model discloses a high truckle that bears.
