Description

Technical Field

[0001] The utility model belongs to the technical field of tensioner wheels, relates to a tensioner wheel, and particularly relates to a novel tensioner wheel. Background Art

[0002] A tensioner is a mechanical device commonly used in automobiles, motorcycles and other mechanical equipment to adjust the tension of a transmission belt or chain to ensure the normal operation of the transmission system.

[0003] The existing tensioner wheel and the belt contact in a sliding friction manner, which easily causes belt wear under long-term use, shortens the life of the belt, and is not conducive to long-term use. Summary of the invention

[0004] The utility model aims to provide a new tensioner with a long service life in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a new type of tensioner, including a base and a tensioner, characterized in that a support column is arranged on the base, a mounting seat for mounting the tensioner is arranged on the support column, a rotating shaft is arranged on the mounting seat, the tensioner is installed on the rotating shaft, an oil storage tank is opened in the tensioner, a plurality of oil outlet holes connected to the oil storage tank are opened on the tensioner, and balls are arranged on the plurality of oil outlet holes.

[0006] In the above-mentioned novel tensioner, an oil injection pipe connected to the oil storage tank is opened on the side wall of the tensioner, a limiting portion is arranged on the inner wall of the oil injection pipe, and a plug is arranged inside the oil injection pipe and relative to the limiting portion.

[0007] In the above-mentioned novel tensioner, a mounting hole for mounting a support column is provided on the base, and the support column is connected to the mounting hole via threads.

[0008] In the above-mentioned novel tensioner, a limiting retaining spring is arranged on the rotating shaft.

[0009] Compared with the prior art, the ball bearings provided in the utility model replace the direct contact between the tensioner and the belt, so that the sliding friction is changed to rolling friction to reduce the friction force, and when the ball bearings roll, they will bring out the oil from the oil storage tank for lubrication to further reduce the friction force, reduce the wear of the belt, and increase the service life.

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 As shown, the novel tensioner comprises a base 1 and a tensioner 2. A support column 3 is arranged on the base 1. A mounting seat 4 for mounting the tensioner 2 is arranged on the support column 3. A rotating shaft 5 is arranged on the mounting seat 4. The tensioner 2 is mounted on the rotating shaft 5. An oil storage tank 6 is provided in the tensioner 2. A plurality of oil outlet holes 7 connected to the oil storage tank 6 are provided on the tensioner 2. Balls 8 are arranged on the plurality of oil outlet holes 7.

[0015] To be more specific, an oil filling pipe 9 connected to the oil storage tank 6 is provided on the side wall of the tensioner 2 , a limiting portion 10 is provided on the inner wall of the oil filling pipe 9 , and a plug 11 is provided in the oil filling pipe 9 and opposite to the limiting portion 10 .

[0016] To be more specific, the base 1 is provided with a mounting hole 13 for mounting the support column 3 , and the support column 3 is connected to the mounting hole 13 via threads.

[0017] To be more specific, a limit spring 12 is provided on the rotating shaft 5 for limiting the position.

[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0019] Although the terms such as base 1, tensioner 2, support column 3, mounting seat 4, rotating shaft 5, oil storage tank 6, oil outlet 7, ball 8, oil injection pipeline 9, limiter 10, plug 11, limiter spring 12, mounting hole 13 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
