Embodiment 1

[0017] Such as figure 1 , figure 2 As shown, the treadmill of the present invention includes a front roller assembly 1, a rear roller assembly 2, and a running belt connecting the front and rear rollers. The front roller assembly 1 includes a front roller 1.1 and a front roller shaft 1.2. The rear drum assembly 2 includes a rear drum 2.1 and a rear drum shaft 2.2. The front drum 1.1 and the two ends of the front drum shaft 1.2 are respectively connected by a rolling bearing 3 . Each between the rear drum 2.1 and the rear drum shaft 2.2 is connected with the same rolling bearing 3 that is located between the two ends of the front drum 1.1 and the front drum shaft 1.2. The rolling bearing 3 is a dust-proof bearing. The inner diameter and width of the rolling bearing 3 are equal to the inner diameter and width of the dust-proof bearing 6202 respectively. The outer diameter of the rolling bearing 3 is greater than or equal to the outer diameter of the dust-proof bearing 6202 p...

Embodiment 2

[0019] The difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, an anti-rotation groove not shown in the figure is provided on both sides of the outer circle of the rolling bearing. The width of the anti-rotation groove is 2 mm and the depth is 1.5 millimeters, length is 4 millimeters, the symmetry plane of groove width of anti-rotation groove passes the axis of rolling bearing. Correspondingly, the ends of the front drum and the rear drum are provided with additional anti-rotation grooves that are adapted to the anti-rotation grooves and not shown in the figure. The width of the additional anti-rotation grooves is 2 mm and the depth is 1.5 mm. mm and a length of 4 mm. An anti-rotation bar not shown in the figure is plugged between the anti-rotation groove and the additional anti-rotation groove. In addition, the width of the rolling bearing is equal to the width of the dust-proof bearing 6202 plus 2 millimeters, so as to improve the rigidity of the rolli...

Abstract

The invention provides a bearing for a treadmill. The treadmill comprises a front roller assembly, a rear roller assembly and a running belt connecting a front roller and a rear roller. The front roller assembly comprises the front roller and a front roller shaft. The rear roller assembly comprises a rear roller and a rear roller shaft. The two ends of the front roller and the two ends of the front roller shaft are connected through two rolling bearings correspondingly. The rear roller and the rear roller shaft are connected through the same rolling bearings as the rolling bearings arranged between the two ends of the front roller and the two ends of the front roller shaft. The rolling bearings are shielded bearings. The inner diameter of each rolling bearing is equal to the inner diameterof each shielded bearing 6202. The outer diameter of each rolling bearing is greater than or equal to the outer diameter, plus 2.8 mm, of each shielded bearing. Meanwhile, the number of steel balls of each rolling bearing is one less than the number of steel balls of each shielded bearing 6202. The bearing for the treadmill has the beneficial effects that the service life of the shielded bearingscan reach 10000 h or more and is far longer than the service life, required by America and other countries, of the shielded bearings. The competitive strength of the treadmill of the company is improved. The prominent and unexpected effects are achieved.

Description

technical field [0001] The invention relates to sports equipment, in particular to a dust-proof bearing for a treadmill. Background technique [0002] Treadmill has obtained great development as a kind of sports equipment, and a lot of people can utilize treadmill to carry out running exercise. Existing treadmills mainly utilize the roller to drive the belt to rotate, keep the belt rotation speed compatible with the pace of the human body, and achieve the purpose of fitness through the continuous running of the user. But treadmills are expensive, easily damaged, and costly to repair. Especially the bearing in the treadmill is a wearing part, which is difficult to replace. Therefore, the United States and other countries have put forward the service life of the bearings used in my country's local treadmills that is much higher than our domestic requirements. How to improve the service life of the bearings used in my country's treadmills is directly related to whether our co...
