Description

Heavy universal wheel

Technical Field

The utility model relates to a haulage equipment technical field specifically is a heavy universal wheel.

Background

In the modern industrial production process, a mold is used in many fields, the used mold has larger access on various parameters along with different produced products, the mold inevitably needs to be moved necessarily when in use, the movement of a small mold is relatively easy to realize, but the mold for producing heavy equipment is often counted by tons, the movement of the mold in the level is difficult to realize only by manpower and common mechanical equipment, based on the condition, technical personnel in related fields design a transport vehicle for carrying the heavy equipment and the mold, in order to ensure the flexible movement of the transport vehicle, a universal wheel becomes the priority of a wheel part, but the particularity of the transported objects causes obvious defects of the existing universal wheel, such as insufficient flexibility in rotation, weak impact resistance, insufficient strength and the like, which often form obstacles to the normal production, this is obviously undesirable for the manufacturer concerned, and it is therefore highly desirable for the skilled person in the field concerned to provide a heavy-duty universal wheel which ensures both the flexibility of rotation and sufficient strength.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a heavy universal wheel.

A heavy universal wheel comprises a bracket, a rubber wheel is arranged at the lower part of the bracket, a wheel axle is arranged at the center of the rubber wheel, and the rubber wheel is connected with the bracket through the wheel axle, and the heavy universal wheel is characterized in that: the support top sets up the main shaft, main shaft upper portion sets up mounting flange, mounting flange upper portion inboard sets up deep groove ball bearing, the mounting flange bottom sets up flat bearing, the main shaft with deep groove ball bearing the flat bearing is fixed connection respectively.

Further, a double-taper bearing is arranged between the wheel shaft and the rubber wheel.

Furthermore, a gland is arranged at the top of the main shaft, a positioning bolt is arranged at the top of the gland, and the gland is connected with the main shaft through the positioning bolt.

Furthermore, the main shaft is connected with the support in a welding mode.

Further, the mounting flange surface equidistance annular runs through and sets up the mounting hole, the quantity of mounting hole is 8.

The utility model discloses a beneficial effect of heavy universal wheel does:

1. the traditional universal wheel is usually only provided with a group of plane bearings to realize the normal operation of the main shaft, and meanwhile, the pressure in the axial direction borne by the main shaft is balanced, but the main shaft is also stressed in the radial direction when the main shaft is turned, in addition, the heavy equipment has larger weight, if the pressure balance in the radial direction of the main shaft can not be well done, the universal wheel is easily damaged, the pressure balance in the radial direction of the main shaft is realized by the deep groove ball bearing arranged on the upper part of the main shaft, and the problem that the traditional universal wheel is not enough in strength and easy to damage is well solved;

2. the double-taper bearing is arranged between the wheel shaft and the rubber wheel, so that the vertical downward force applied to the wheel shaft is decomposed into forces in two directions which are vertical to the wheel shaft and parallel to the wheel shaft, the pressure in the vertical direction which can cause the wheel shaft to break is obviously reduced, and the strength of the heavy universal wheel is further enhanced;

3. the equidistance annular runs through the mounting flange that sets up the mounting hole, the gland that positioning bolt is fixed and main shaft and the support of connecting through the welding mode, has promoted this heavy universal wheel installation process effectively and as an holistic stability.

Drawings

In order to illustrate the embodiments of the present invention or the technical solutions in the prior art more clearly, the drawings used in the description of the embodiments or the prior art will be briefly described below, but the protection scope of the present invention is not limited thereto.

Fig. 1 is a schematic sectional view of a heavy universal wheel according to the present invention;

fig. 2 is a perspective view of the heavy universal wheel of the present invention.

The wheel comprises a gland 1, a deep groove ball bearing 2, a mounting flange 3, a plane bearing 4, a main shaft 5, a support 6, a rubber wheel 7, a double-taper bearing 8, a positioning bolt 9, a mounting hole 10 and a wheel shaft 11.

Detailed Description

For the sake of clarity, the heavy universal wheel of the present invention will be further described with reference to fig. 1 to fig. 2 of the drawings attached to the specification.

A heavy universal wheel comprises a bracket 6, a rubber wheel 7 is arranged at the lower part of the bracket 6, a wheel shaft 11 is arranged at the center of the rubber wheel 7, the rubber wheel 7 is connected with the bracket 6 through the wheel shaft 11, and the heavy universal wheel is characterized in that: 6 tops of support set up
