Definitions
- the present invention relates to a chain used for high-precision transmission and conveyance requiring low friction and wear, and in particular, to a chain provided with a bin that can rotate freely with respect to a link plate. About one.
- Roller chains and bush chains which have been generally used for transmission and transportation, have their bottles fixed to the outer link plate and the bushings fixed to the inner link plate. Therefore, since the bin and the bush come into sliding contact with each other, the friction and wear are large, and the tune elongates along with the power loss. This makes it unsuitable for applications that require high-precision positioning. In addition, the bush and roller wear and noise due to the engagement of the chain and the block are large. As a measure to reduce friction and wear, it is known to incorporate needle roller bearings between the bin and bush. Therefore, there is a problem that the diameter of the bottle becomes smaller and the load capacity is reduced.
- the present invention provides a transmission and transport tune with low friction and wear, high load capacity and low noise.
- the triple structure of the conventionally used bin bush rollers will be eliminated, and the structure will be such that the bins can rotate with low friction for all link braces that connect adjacent bins.
- Rolling bearings are suitable for this purpose, but sliding bearings can also be used if the diameter of the bin is increased.
- a tune according to an aspect of the present invention includes a plurality of bins that are arranged in parallel and at regular intervals to each other and each have a tooth surface that directly contacts a tooth surface of a sub-block, and two adjacent bins.
- each bin is supported by at least one rolling bearing provided on one link plate and a sliding bearing provided on the other link plate. Due to the difference in friction between the sliding bearing and the rolling bearing, bending when the chain is caught in the sprocket is allowed by the rotation of the bin by the rolling bearing.
- the tooth surface where the chain and the sprocket teeth engage is provided on the outer peripheral surface of the bin or the outer peripheral surface of the outer ring of the rolling bearing.
- the outer periphery of the bin is used as the tooth surface
- half of the rolling bearing and half of the sliding bearing may be provided.
- the outer ring of a rolling bearing is used as a tooth surface
- a part of the outer peripheral surface of the rolling bearing is supported by a sliding bearing, and the side of the link plate that engages the tooth surface of the A space is provided to allow the penetration of the sprocket teeth, and the outer peripheral surface of the outer ring of the rolling bearing exposed in the space is used as a tooth surface that meshes with the sprocket tooth surface. Engagement with the sub-block takes place by rolling contact and does not require rollers.
