Abstract

The utility model relates to a treadmill band pulley, band pulley are established respectively at treadmill support body both ends, the thin layer below the band pulley surface cladding one deck 1mm, and the high friction surface is made with the belt contact surface to the thin layer. Therefore, the purposes of pressure resistance, no deformation and better applicability can be achieved.

Description

treadmill with wheels

technical field

The utility model relates to a treadmill pulley, in particular to a treadmill pulley whose surface is coated with a layer of high-friction film.

Background technique

Treadmill is a well-known exercise and fitness equipment. As shown in Figure 1, the treadmill has a frame body 10, and the two ends of the frame body 10 are provided with pulleys 20, and the belt wheels 20 are wound with a belt body 11 for a runner to step on. The belt pulley 20 is generally a metal round tube, and the surface is relatively smooth if it is not processed. Therefore, if the belt body 11 is to be reliably driven to roll, it must have better friction. The existing solutions are as follows:

1. As shown in Fig. 2, the roller flower 21 is directly processed on the surface of the pulley 20 to increase the friction force. The disadvantage of this method is that the processing of the roller flower 21 will destroy the roundness of the pulley 20, and even affect the rotation of the pulley 20. smooth, and may increase noise, shorten the service life of components, and reduce product quality;

2. As shown in Figure 3, a rubber layer 22 is coated on the surface of the pulley 20 to generate friction. The disadvantage of this method is that the treadmill often goes through a long storage period from the completion of manufacturing and assembly to the sale and use. The various parts of the machine are obviously in a fixed state. Since the pulleys 20 at both ends have a certain tension, the rubber layer 22 of the belt body 11 is only squeezed on the outside for a long time, and its flexibility and elasticity will change and even deform. , and cannot be restored, it will also cause unsmooth conduction in future use.

Contents of the invention

The purpose of the utility model is to provide a treadmill pulley that can withstand pressure without deformation, run smoothly, prolong the service life of components, and improve product quality.

The purpose of this utility model is achieved through the following technical means: a treadmill pulley, which is assembled at both ends of the treadmill frame, with a belt body wound around it, and the surface of the pulley is coated with a layer of rubber with a thickness below 1mm. The thin film layer, the contact surface between the thin film layer and the belt body is made into a high friction surface.

The utility model has the advantages of: 1. The utility model borrows the high-friction surface film layer coated on the surface of the pulley, which can avoid the disadvantages of the prior art that the processing of roller flowers on the pulley causes the deformation of the pulley, and can keep the pulley The true roundness achieves the purpose of smooth transmission, prolonging the service life of components and improving quality.

2. The thickness of the film layer of the present invention is less than 1mm, so the amount of deformation under pressure can be completely ignored, so the purpose of pressure resistance without deformation and better applicability can be achieved.

Detailed ways

The structure of the utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Fig. 1, Fig. 4 and Fig. 5, the treadmill pulley 20 of the present utility model is set at two ends of the treadmill frame body 10, and a belt body 11 is wound thereon. The surface of the pulley 20 is coated with a film layer 30 with a thickness of less than 1 mm, and the contact surface between the film layer 30 and the belt body 11 is made into a high friction surface 31 . The high-friction surface film layer coated on the surface of the pulley 20 can avoid the disadvantages of the existing technology that the processing of roller patterns on the pulley 20 causes the deformation of the pulley 20, and can maintain the roundness of the pulley 20 to achieve smooth transmission and drive. The purpose of prolonging the service life of components and improving quality. The thickness of the thin film layer 30 of the present invention is less than 1mm, so the amount of its deformation under pressure can be ignored completely, so it can achieve the purpose of no deformation under pressure and better applicability.
