Abstract

The utility model discloses a bearing roller conveyor chain, which comprises inner link plates, outer link plates, sleeves, bearings, rollers, pins and the like. Each sleeve sleeved outside each pin is in interference fit with the pin, each bearing is sleeved outside each sleeve, an inner ring of each bearing is in interference fit with each sleeve, the rollers are sleeved outside the bearings, an outer ring of each bearing is in interference fit with the rollers, the rollers and the sleeve are in rolling friction, and by aid of the rolling friction, resistance to the chain in running is reduced greatly so that the maximum tension of the chain is reduced. On the premise of sharing the same load, users can select chains in the dimension smaller than that of the general roller chains, and frequency of injecting lubricating oil to maintain the chains is reduced greatly.

Description

The bearing roller conveyer chain

Technical field

The utility model belongs to the load transfer device parts, relates in particular to a kind of sleeve-barrel roollr chain device that contains bearing arrangement.

Background technology

The chain strip transmission line is to carry out the equipment of convey materials with chain as traction and supporting body, and the chain strip transmission line is to carry on the chain, adding a higher carrier roller annex between every joint and come bearing goods.And chain is to come and the track roll-sliding with roller.Because roller and track on the chain are with rolling touch, friction drag is little, and kinetic equation loss is low and can carry heavier loading.Its loading capacity and support intensity, chain size and roller size, material all have relation, and the roller material is generally steel, but some occasion is in order to reduce noise, and adopt the engineering plastics manufacturing of abrasion performance.Chain can adopt common sleeve-barrel roollr conveyer chain, also can adopt other various special chain drives (as gathering chain, double-speed chain).At the common sleeve-barrel roollr conveyer chain of general employing, under guide supporting, go, owing to be sliding friction between roller and the sleeve in sleeve transhipment last time, so frictional resistance is big, as reducing cliding friction, can only strengthen chain tension, and then significantly reduced the service life of chain.

The utility model content

The purpose of this utility model provides and a kind ofly can reduce the chain friction coefficient significantly, the bearing roller conveyer chain that the maximum tension that is born reduces.

For achieving the above object, the utility model is achieved through the following technical solutions.The bearing roller conveyer chain, comprise inner plate, pin link plate, sleeve, bearing, roller, parts such as bearing pin, wherein a pair of pin link plate of left-right symmetric and bearing pin are by the trepanning socket on the pin link plate, the a pair of inner plate of left-right symmetric with by the trepanning bearing pin socket on the inner plate, inner plate is positioned at the pin link plate inboard, sleeve be positioned at each pin link plate inboard and with the bearing pin socket, bearing be positioned at each inner plate inboard and with the sleeve socket, roller be positioned at each inner plate inboard and with the bearing socket, wherein the inner link in the link chain mechanism is made up of two sleeves and a pair of inner plate of left-right symmetric, outer link is made up of two bearing pins and a pair of pin link plate of left-right symmetric, sleeve and a pair of inner plate interference fit, sleeve cooperates with bearing space, bearing and roller interference fit.

The utility model compared with prior art has the following advantages: (one) is after having added bearing between sleeve and the roller, form rolling friction between roller and the sleeve, resistance when rolling friction can reduce the chain operation significantly, thereby the maximum tension that chain is born reduces, like this, under the identical load situation, just can select than the original little chain of common roller chain specification, also can significantly reduce the number of times that chain filling lubricating oil carries out maintaining; (2) be that moment frictional resistance variation is less, can avoid the creep situation of chain when low-speed heave-load moves to a great extent, the crawling problems that chain occurs in operation process is difficult to resolve determines, the general only method effect with the tensile force that increases chain is not remarkable, but also bring the negative effect that increases the chain working tension, be particularly suitable in the use occasion of difficulty of heavy duty, low speed and maintaining.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As Fig. 1, shown in Figure 2, the bearing roller conveyer chain, comprise inner plate 1, pin link plate 2, sleeve 3, bearing 4, roller 5, bearing pin 6 parts such as grade, wherein a pair of pin link plate 2 of left-right symmetric and bearing pin 6 are by the trepanning socket on the pin link plate 2, a pair of inner plate 1 of left-right symmetric and trepanning bearing pin 6 sockets of passing through on the inner plate 1, inner plate 1 is positioned at pin link plate 2 inboards, sleeve 3 be positioned at each pin link plate 2 inboard and with bearing pin 6 sockets, bearing 4 be positioned at each inner plate 1 inboard and with sleeve 3 sockets, roller 5 be positioned at each inner plate 1 inboard and with bearing 4 sockets, wherein the inner link in the link chain mechanism is made up of two sleeves 3 and a pair of inner plate 1 of left-right symmetric, outer link is made up of two bearing pins 6 and a pair of pin link plate 2 of left-right symmetric, sleeve 3 and a pair of inner plate 1 interference fit, sleeve 3 and bearing 4 free-running fits, bearing 4 and roller 5 interference fit.

The principle of work of the utility model embodiment is: sleeve 3 is sheathed on bearing pin 6 outer and interference fit, and bearing 4 is sheathed on outside the sleeve 3, bearing inner ring 8 and sleeve 3 interference fit, and roller 5 is sheathed on outside the bearing 4, outer race 9 and roller 5 interference fit.A pair of inner plate 1 of left-right symmetric and bearing pin 6 interference fit, a pair of pin link plate 2 of left-right symmetric and bearing pin 6 free-running fits, roller 5 is used for the bearing goods load-transfer device.

After making the chain structure motion by the bearing roller chain of the utility model embodiment forecast scheme configuration by the power gear dribbling is moving, the roller 5 of the goods of carrying produces downward pressure and directional pull according to the power gear sense of motion for inner link, bearing inner ring 8 produces the contrarotation campaign by above two bursts of external force between the two with outer race 9, and both and bearing ball 7 produce friction of rolling.
