Description

Bearing pipe sleeve of riding platform

Technical Field

The utility model relates to the technical field of riding platforms, in particular to a bearing pipe sleeve of a riding platform.

Background

The intelligent riding platform is an important riding power auxiliary product in the existing market, can effectively help players to simulate the riding state in the field, and effectively improves the power of the players. The general intelligent riding platform comprises a power module, a base and supporting legs, and is used as a carrier for transmission and rotation, and a bearing pipe sleeve determines the running stability of a product.

The phenomenon of vibration, noise in the platform use is ridden to current market intelligence is mostly because the bearing has produced the damage and has caused, and cause the bearing easily bad main reason exactly, the pipe box welding of installation bearing is heated and is warp, has caused the extrusion to the bearing to can appear vibration and abnormal sound after leading to the product to use a period.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that the bearing is extruded after the existing bearing pipe sleeve is installed, so that the bearing is damaged, and provides a riding platform bearing pipe sleeve.

The utility model is realized by adopting the following technical scheme:

a bearing pipe sleeve of a riding platform is provided with a bearing position, the bearing position is arranged inside the pipe sleeve, the bearing pipe sleeve further comprises a fixed connection position, a tool press-fitting position, a tool press-avoiding vacancy and an expansion position, the tool press-fitting position is arranged at an upper end opening of the pipe sleeve, the tool press-avoiding vacancy is arranged between the tool press-fitting position and the bearing position, an annular bevel-opening inner groove is circumferentially arranged on the outer wall of the pipe sleeve at the tool press-fitting position, the cut angle of the bevel-opening inner groove faces the upper end opening of the pipe sleeve, the pipe sleeve wall above the bevel-opening inner groove is the expansion position, the fixed connection position is arranged on one section of the outer wall of the pipe sleeve below the expansion position, the diameter of the fixed connection position is smaller than that of the pipe sleeve below the fixed connection position, the fixed connection position is in interference fit with a main beam pipe of the riding platform, and the magnitude of interference of the expansion position is increased after the riding platform is in place.

Furthermore, after the press mounting is in place, the single-side interference magnitude of the expansion position is increased by 1 mm.

Furthermore, the two bearing positions are respectively arranged at two ends of the pipe sleeve.

Further, the diameter of the tool press-mounting position is gradually increased from bottom to top.

The utility model has the following beneficial effects: the welding on the main beam is not needed, so that the deformation caused by welding heating is reduced, and abnormal sound caused by subsequent deformation is reduced; the installation is convenient, and the maintenance is more convenient; the product is thinner and lighter.

FIG. 2 is a schematic diagram and an enlarged view of a part II of the riding platform after the bearing pipe sleeve tool is installed.

Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

Examples

A bearing pipe sleeve of a riding platform is shown in figure 1, and is provided with a bearing position 1, a fixed connection position 2, a tool press-mounting position 3 and an expansion position 4, wherein the number of the bearing positions 1 is two, and the two bearing positions are arranged at two ends inside the pipe sleeve and used for mounting bearings. The tool press-fitting position 3 is arranged at an opening at the upper end of the pipe sleeve, the diameter of the tool press-fitting position gradually increases from bottom to top, and the tool press-fitting position is a position for applying pressure on the pipe sleeve by press-fitting equipment. A tool compression avoidance vacancy 5 is arranged between the tool press-mounting position 3 and the bearing position 1 and used for providing deformation of a space buffer tube sleeve in the radial direction and avoiding extrusion of the bearing position. An annular bevel-opening inner groove 6 is circumferentially arranged on the outer wall of the pipe sleeve at the tooling press-fitting position 3, the cut angle of the bevel-opening inner groove 6 faces to an opening at the upper end of the pipe sleeve, and the pipe wall of the pipe sleeve above the bevel-opening inner groove 6 is an expansion position 4. The fixed connection position 2 is arranged on the outer wall of a section of the pipe sleeve below the expansion position 4, the diameter of the fixed connection position 2 is smaller than that of the pipe sleeve below the fixed connection position 2, the fixed connection position can be in interference fit with a main beam pipe of the riding platform, and after the pressing and mounting are in place, the magnitude of interference at the expansion position 4 is increased.

The depth and the wall thickness of the inner groove with the inclined opening are designed by calculating the yield strength and the elongation of metal, and in the press fitting process, as the position of the inner groove with the inclined opening can deform, after the press fitting is in place, as shown in figure 2, an expansion position above the inner groove with the inclined opening protrudes outwards, and the interference of 1mm can be increased on one side. The deformation absorption of the tooling position is arranged at the notch position, so that the bearing position is not influenced, the size position of the bearing is ensured, and the extrusion to the bearing is reduced. The pipe sleeve is installed into the main beam in a clearance fit mode, the inner groove of the bevel connection is just right located on one side of the wall of the main beam after the pipe sleeve is installed in place, the relative position of the pipe sleeve and the main beam is guaranteed, the pipe sleeve is pressed down through a hydraulic machine, the flanging is extruded, the inner groove of the bevel connection is firmly attached to the wall of the main beam, and loosening is prevented.

In the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be understood broadly, and may be, for example, a fixed connection, a detachable connection, or an integral connection; they may be connected directly or indirectly through an intermediate. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
