Abstract

The utility model relates to a special wheel of reinforced plastic rubber universal wheel, which is composed of an outer ring of wheel and a bearing rib arranged in the outer ring. The utility model is characterized in that the bearing rib is composed of primary ribs, oblique ribs and auxiliary ribs, wherein both sides of each primary rib are respectively provided with an oblique rib, and all the oblique ribs reach a convergence point and then directly reach the auxiliary ribs. Both sides of each auxiliary rib are respectively provided with an oblique rib, and the two oblique ribs of each auxiliary rib reach a convergence point from the outer ring of wheel to make the two oblique ribs and the outer ring of wheel form an isosceles triangle. The unique conformation can effectively divide force to change single rib force into multi-rib force, thereby achieving the objectives of reducing material, lowering the cost and extending the service life of the wheel.

Description

The special-purpose wheel of heavier-duty synthetic resin universal wheel

Technical field

The utility model relates to the improvement of cardan wheel, the special-purpose wheel of particularly a kind of heavier-duty synthetic resin universal wheel.

Background technology

Wheel is a single wheel on the plastic cement steering wheel, is a main accessory of synthetic resin universal wheel.The main rib position of existing synthetic resin universal wheel wheel is generally 68 or 12 through wheel outer rings, when whole wheel after the assembling is being rotated, the local main rib position that main rib position is arranged is because of stressed flexural deformation, and do not have the place of main rib position to fracture because of the big and stressed depression of span, shortened the service life of wheel.At the problems referred to above, normally the method with thickness that increases the outer ring face and increase rib position thickness solves, and the result increases cost greatly, and effect and not obvious.

Summary of the invention

The purpose of this utility model is to provide a kind of holding capacity big, and materials are few, and cost is low, and the special-purpose wheel of glue cardan wheel is moulded in long-lived reinforcement.

The purpose of this utility model is to be achieved by the following scheme: be made of wheel outer ring and the stressed rib bit pattern that is located in the outer ring, triangle and rhombus support level are formed by main rib position, diagonal rib position and auxiliary rib position three parts in wherein said stressed rib position, be provided with a diagonal rib position on the both sides of every main rib position, by each diagonal rib position to joint, again by the through coupled auxiliary rib position of joint, simultaneously in many diagonal rib positions, the both sides of every auxiliary rib position, be intersected in a meeting point by the wheel outer ring, make the face of two diagonal rib positions and wheel outer ring form an equicrural triangle.

Advantage of the present utility model is: the stressed rib position that is made of triangle and rhombus, 24 support levels on the face of wheel outer ring, have been formed, be equivalent to have 24 main rib positions to support, the distance of rib interdigit is shortened, it is many that support level becomes, and effectively strength disperseed, and becomes many appropriate design that the rib position is stressed with single rib position is stressed, the holding capacity of wheel can be improved more than 1 times, prolonged wheel service life.And the thickness of outer ring face and the thickness of rib position are also significantly reduced, materials can reduce more than 30%, effectively reduce productive costs.

Description of drawings

Below in conjunction with accompanying drawing the utility model is illustrated.

Figure 1 shows that existing wheel structure scheme drawing;

Fig. 2 moves towards scheme drawing for the existing stressed position of wheel force distribution;

Fig. 3 is the utility model structural representation;

Fig. 4 moves towards scheme drawing for the stressed position force distribution of Fig. 3.

The specific embodiment

As shown in Figure 3, Figure 4: the utility model is the principle design of utilizing triangle, rhombus support level and reducing bearing surface support level distance, make the diagonal rib position 2,3 of the internal structure shape of wheel by main rib position 1 and main rib position, joint 4,5, service bit 6,7, the diagonal rib position 8,9 of service bit 6, the diagonal rib position 10,11 of service bit 7 and wheel outer ring 12 are formed.A diagonal rib position 2 is wherein arranged on the both sides of every main rib position, 3 support, the loxosis of diagonal rib position and other main rib position is intersected in a bit, main rib position 1 is when stressed, strength is made the stressed minimizing of main rib position by stages along the diagonal rib position, and it is not yielding, again by the auxiliary rib position 6 and 7 of the through wheel outer ring 12 of joint, many diagonal rib positions 8, the both sides of every auxiliary rib position and 9 outer rings 12 by wheel are intersected in a meeting point 4 and 5, article two, diagonal rib position and wheel outer ring face form an equicrural triangle, add the support of auxiliary rib position in the center, the strong point of wheel outer ring face is increased, the distance of the wheel outer ring face strong point reduces significantly, and the stressed while of wheel outer ring face also increases substantially.Principle of work is:

After the wheel assembling, when rotating wheel go to rib position 1 local time, diagonal rib position 2 and 3 was supported and is withstood when main rib position 1 was stressed, strength is gone to joint 4 and 5, go to auxiliary rib position 6 and 7 and the diagonal rib position 8,9,10,11 of service bit by joint 4,5 again, and the diagonal rib position of other main rib position, thereby the strength that main rib position 1 is born is gone on other rib position, strength is shared made main rib position not yielding, crooked (as shown in Figure 4).When wheel goes to auxiliary rib position 6, auxiliary rib position 6 is stressed, strength is gone to joint 4, again by on joint 4 diagonal rib position 2 that goes to main rib position and the diagonal rib position of facing main rib position mutually, add the support of the diagonal rib position 8,9 of auxiliary rib position, it is stressed that the strength that auxiliary rib position 6 is born goes to many rib positions, makes auxiliary rib position stressed little and not yielding.When the wheel rotor is between the place 10 and 7 that does not have support level, because of the distance of the support level of outer ring face and support level little, strength is shared by auxiliary rib position 7 and auxiliary rib position 10 and is gone to joint when the outer ring face is stressed, go on other the rib position by joint 5 again strength is disperseed, the room of adding the outer ring face is few, and intensity is improved greatly.

Claims

The special-purpose wheel of a kind of heavier-duty synthetic resin universal wheel, constitute by wheel outer ring (12) and the stressed rib bit pattern that is located in the outer ring, it is characterized in that: said rib position is by main rib position, diagonal rib position and auxiliary rib position three parts are formed triangle and rhombus support level, be provided with a diagonal rib position (2) (3) on the both sides of every main rib position (1), by each diagonal rib position to joint (4) (5), again by the through coupled auxiliary rib position (6) (7) of joint (4) (5), simultaneously in many diagonal rib positions (8) (9) (10) (11), the both sides of every auxiliary rib position, be intersected in a meeting point by wheel outer ring (12), make two the diagonal rib positions (8) (9) and the face of wheel outer ring (12) form an equicrural triangle.
