Abstract

The rolling member chain is adapted to hold and position the plurality of rollers in a straight line apart, and has a belt assembly and a plurality of clamping assemblies. The roller is a cylinder mounted parallel to the rolling member chain. The belt assembly is elastic and has two parallel bars. The clamping assemblies are formed in pairs between parallel bars to form a plurality of roller holes in the belt assembly, each clamping assembly having a plurality of clamping protrusions. The clamping protrusions of each clamping assembly are formed in a straight line between the parallel bars and alternately project from the belt assembly to the opposite side and hold together one corresponding roller in the belt assembly. Each clamping protrusion has a roller surface and one or more vertices. One or more vertices are formed protruding from the roller surface, thereby reducing the contact area between the clamping protrusion and the roller.

Description

Rolling member chain {ROLLING ELEMENT CHAIN}

The present invention relates to a rolling member chain in which the internal resistance is reduced and its life and efficiency are increased.

Rolling member chains are used to space apart a plurality of rolling members, such as cylindrical rollers. Some rolling member chains also include lubricants to lubricate the rolling members and extend their life.

Referring to FIGS. 7 and 8, the conventional rolling member chain 40 is applied to hold and arrange the plurality of rollers 90, two parallel bars 41, a plurality of receiving holes 43, and A plurality of retaining members 42 are included.

The rollers 90 are arranged in parallel in rows and each has an annular surface and two ends. The bars 41 are each connected to the ends of the rollers 90 and are parallel to each other. Receiving holes 43 are formed between these bars 41 and are aligned with each other and each has a retaining side. Retaining members 42 are each mounted in receiving holes 43 near the retaining side, and each retaining member 42 has a plurality of retaining surfaces 421, 422, 423 adjacent to each other.

Retaining surfaces 421, 422, 423 of adjacent retaining members 42 contact the annular surfaces of corresponding rollers 90. Bar 41 also contacts the end of each roller 90. This contact is mainly surface to surface contact. Therefore, a lot of friction occurs, which adversely affects the rolling motion of the roller 90 and requires lubrication between the roller 90 and the bar 41 for efficiency and longevity.

To overcome this drawback, the present invention provides a rolling member chain to alleviate or eliminate the above problem.

The main object of the present invention is to provide a rolling member chain which is equipped with a plurality of rolling members and has a reduced contact area with the rolling members.

The rolling member chain is adapted to hold and arrange the plurality of rollers apart, and has a belt assembly and a plurality of clamping assemblies. The roller and the cylinder are mounted parallel to the rolling member chain. The belt assembly is elastic and has two parallel bars. Clamping assemblies are formed in pairs between the parallel bars to form a plurality of roller holes in the belt assembly, each clamping assembly having a plurality of clamping protrusions. The clamping protrusions of each clamping assembly are formed in a straight line between the parallel bars, alternately projecting oppositely from the belt assembly and holding together one corresponding roller in the belt assembly. Each clamping protrusion has a roller surface and one or more vertices. Each rib is formed on and protrudes from the surface of the roller, reducing the area of contact between the clamping protrusion and the roller.

Other advantages and features of the present invention will become more apparent from the following detailed description with reference to the accompanying drawings.

According to the present invention, there is provided a rolling member chain which is equipped with a plurality of rolling members and whose contact area with the rolling members is reduced.

The rolling surfaces of each parallel bar 13, 23, 33 are opposite to each other and perpendicular to the inside of the parallel bars 13, 23, 33.

The bosses 110, 210, 310 are formed to protrude centrally from the supporting surfaces of the parallel bars 13, 23, 33, respectively, each of which is in contact with the center of each end of the roller 50, thereby providing a belt assembly ( 11, 21, 31 and the contact area between the roller 50 is reduced.

The clamping assemblies 12, 22, 32 are formed between parallel bars 13, 23, 33 to form a plurality of roller holes 111, 211, 311 on the belt assemblies 11, 21, 31.
