Description

A sprocket wheel edge capable of preventing dust accumulation

Technical Field

The utility model relates to the technical field of sprocket wheels, in particular to a sprocket wheel edge capable of preventing dust accumulation.

Background Art

A sprocket is a wheel with cog-shaped sprocket teeth, which is used to mesh with the block with accurate pitch on the link chain or cable. Sprockets can be divided into inner sprockets and outer sprockets according to the structural form of the sprocket guide inside the chain. According to the lubrication method on the sprocket wheel side, there is a difference between dry wheel side and wet wheel side. Dust or impurities will adhere to the sprocket wheel side, which needs to be cleaned manually, otherwise it will affect the transmission effect.

The publication (announcement) number is CN219954142U, which discloses a sprocket wheel edge with a self-cleaning structure, including a circular connector, a rotating shaft and a connecting plate, the outer side of the circular connector is sleeved with a sprocket wheel edge, the middle part of the surface of the circular connector is provided with an axial center hole, and the rotating shaft passes through the axial center hole. The utility model drives the driving gear to rotate while the rotating shaft rotates. Since the driving gear and the driven gear are sleeved with a transmission belt, the driving gear rotates and the driven gear rotates. The driven gear rotates and the rotating rod rotates. The rotation of the rotating rod drives multiple blades to rotate, and the dust or impurities attached to the sprocket wheel edge are blown off, which has a self-cleaning effect on the sprocket wheel edge, does not require manual cleaning, and does not require an additional power source. The structure is reasonably designed and is more convenient to use, which prevents the sprocket wheel edge from being attached with dust or impurities that affect the transmission effect.

Although the above scheme can clean the dust or impurities on the wheel edge, when the sprocket body is assembled to the transmission shaft, the transmission parts that cooperate with the rotation of the fan blades must also be assembled to the transmission shaft one by one and multiple bearings and auxiliary support shafts must be installed. Before the dust-proof cleaning parts are disassembled and maintained, the transmission shaft and the sprocket body must be removed first. The equipment is troublesome and laborious to disassemble and maintain the dust-proof cleaning parts. For this reason, we propose a sprocket wheel edge that can prevent dust accumulation.
