Description

Technical Field

[0001] The utility model relates to the technical field of idler wheels, in particular to an idler wheel structure. Background Art

[0002] An idler gear refers to a gear that plays a transmitting role between two transmission gears that do not contact each other. It meshes with these two gears at the same time to change the rotation direction of the passive gear to make it the same as the driving gear. Its function is only to change the direction of rotation and cannot change the transmission ratio. It is called an idler gear. The idler gear is a gear train part that plays a transitional role and will not change the transmission relationship. It is to make the gear train force more reasonable or to meet the layout of the entire transmission system. The wheelbase can be extended through the idler gear. The number of its teeth has no effect on the value of the transmission ratio, but it will affect the direction of rotation of the final wheel. It is a wheel that does not do work and has a certain energy storage effect, which is helpful for system stability.

[0003] Idle wheels are widely used, however, traditional idle wheels still have some shortcomings. For example, their structure is relatively fixed, so when they need to be replaced or maintained, they need to be disassembled and installed as a whole. As a result, not only is the maintenance process time-consuming and labor-intensive, the efficiency is low, and the cost of overall replacement and maintenance is also relatively high. Therefore, an idler wheel structure is proposed to address the above problems. Utility Model Content
