Problems solved by technology
However, in actual operation, since the tensioning wheel needs to frequently tension the transmission parts of the transmission equipment, the swing arm frequently swings relative to the fixed base. In this case, it is easy to generate static electricity in the tension adjustment device.
In practice, the sliding bearing is usually a plastic material with self-lubricating properties, which is insulative and cannot immediately lead out the electrostatic charge of the pulley arm in the tension adjustment device, resulting in the accumulation of electrostatic charge, which in turn generates electric sparks
In addition, in some products, the sliding bearing is made of conductive materials, such as copper. In order to ensure the lubricity of the sliding bearing, a plastic material with self-lubricating properties will be placed on the surface of the copper material, which will not lead to the tension adjustment device immediately. Electrostatic charge on the middle pulley arm, resulting in the accumulation of electrostatic charge, which in turn generates an electric spark
The resulting electric sparks may cause accidents such as fire

Disclosed is a tension adjustment device (100) for transmission equipment. The tension adjustment device (100) comprises: a swing arm (10), the swing arm (10) being rotatably fixed via a fixing assembly (60); and a tensioning assembly (20), the tensioning assembly (20) being rotatably fixed to the swing arm (10), wherein the swing arm (10) is provided with a swing arm shaft (11), a hole (12) is formed in the swing arm shaft (11), the fixing assembly (60) is assembled in the hole (12), a bearing assembly (62) is arranged between the fixing assembly (60) and the hole (12), a first sealing cover (63) is arranged at one end portion of the fixing assembly (60), an electro-static discharge member (65) is arranged between the first sealing cover (63) and the swing arm shaft(11), and the electro-static discharge member (65) makes contact with the first sealing cover (63) and the swing arm shaft (11) respectively, so as to form an electro-static discharge path. By means of this structure, the static electricity generated during the operation of the tension adjustment device (100) can be eliminated.
Description
technical field [0001] The present invention relates to a tension adjusting device having a static discharge path to discharge static electricity generated during operation of the tension adjusting device. Background technique [0002] The tension adjusting device is widely used in transmission equipment, and transmission components such as belts or chains of the transmission equipment are usually pressed against the tensioning pulley of the tension adjusting device, and the running transmission components are tensioned by the tensioning pulley during the operation of the transmission equipment. A tensioning device typically includes a swing arm and a tensioning assembly. Wherein the swing arm is rotatably fixed to a fixed base through a fixing assembly, and the fixed base may be, for example, an engine block or a mounting bracket. [0003] Chinese patent CN100441912C discloses a tension adjustment device for driving belts for auxiliary machinery, which can maintain the sea...
