Problems solved by technology

Although this method can meet the requirements to a certain extent through special equipment and tooling, the problems of increased production process, increased production cost and increased risk of quality management need to be overcome
[0005] Although the injection-molded plastic pipe can meet the requirements of the concentricity of the bearings at both ends and the radial runout of the outer circle, the production efficiency is significantly lower than that of extrusion molding, and the injection-molded pipe is easily affected by the molding process, ambient temperature, cooling rate, and workers. Influenced by factors such as technical level, it is easy to deform after leaving the mold, and its residual stress will also have an adverse effect on the entire use of the product

Embodiment 1

[0038] Such as figure 1 , Figure 7 , Figure 11 As shown, the plastic idler roller of the axial laminated contact / non-contact combined sealed belt conveyor in this embodiment includes an idler shaft 8, which is supported and sleeved on the bearing housing 2 by bearing housings 2 and 7 arranged at both ends of the shaft. The modified PVC roller body 1, and the axial laminated contact / non-contact combined seal sealed in the annular cavity between the bearing housing 2 and the idler shaft 8 through the end cover 4; the axial laminated contact / The non-contact combined seal is composed of an integral structure, a hollow cylindrical lamination seat 3 and an axial combined lamination group 6 installed in the sealing groove processed around the outer wall of the lamination seat; the laminations The seat 3 is combined with the idler shaft 8 in the form of interference fit, and the radial gap between the lamination seat 3 and the bearing seat 2 is a=0.5mm; the width of the sealing ...

Embodiment 2

[0042] Such as Figure 5 , Figure 8 , Figure 12 As shown, the difference between this embodiment and Embodiment 1 is that the axial laminated contact / non-contact combined seal is composed of a split-type, hollow cylindrical lamination seat 3-1 installed in a surrounding The lamination seat 3-1 is combined with the bearing seat 2 in the way of interference fit, and the lamination seat 3-1 is combined with the support The radial gap between the roller shafts 8 is a=0.4mm; the gap between the width of the sealing groove of the lamination seat 3-1 and the total length of the axially combined lamination group 6 is b=0.8mm; the axially combined type The lamination group 6 is composed of laminations with internal tension, and the radial gap with the bottom of the sealing groove of the lamination seat is c=0.4mm, and it is interference fit with the roller shaft 8.

Embodiment 3

[0044] Such as image 3 , Figure 9 , Figure 13 As shown, the difference between this embodiment and Embodiment 1 is that: the axial laminated contact / non-contact combined seal is a laminate seat 3-2, 3-3 of a separate structure composed of upper, middle and lower rings It is composed of an axial combined lamination group 6 installed in the sealing groove around the outer wall of the lamination seat; the lamination seat is combined with the roller shaft 8 in an interference fit manner, and the lamination seat and the bearing seat The radial gap between them is a=0.5mm; the gap between the width of the sealing groove of the lamination seat and the total length of the axial combined lamination set 6 is b=1mm; the axial combined lamination set 6 is composed of It is composed of inner and outer tension laminations arranged at intervals, wherein the outer tension laminations are in interference fit with the bearing seat and the radial gap between the lamination seat sealing groo...

Abstract

The invention discloses an axial laminated contact / noncontact combined sealing tape type conveyer plastic carrier roller. The conveyer plastic carrier roller comprises a carrier roller shaft (8), a polyvinyl chloride (PVC) roller body (1) supported and sleeved on a bearing seat (2) through the bearing seat (2) and a bearing (7) arranged at two ends of the shaft, and an axial laminated contact / noncontact combined seal sealed in an annular cavity between the bearing seat (2) and the carrier roller shaft (8) through an end cover (4). The conveyer plastic carrier roller is characterized in that: the axial laminated contact / noncontact combined seal consists of a lamination seat (3) with a hollow columnar structure and an axial combined lamination assembly (6) arranged in a sealed groove machined in the inner wall or the outer wall of the lamination seat; the lamination seat (3) is combined with the carrier roller shaft (8) or the bearing seat (2) in an interference fit mode, and the radialclearance between the lamination seat (3) and the bearing seat (2) or the carrier roller shaft (8) is 0.1 to 1 millimeter; and the clearance between the width of the sealed groove of the lamination seat (3) and the total length of the axial combined lamination assembly (6) is 0.1 to 1 millimeter.

Description

technical field [0001] The invention relates to a manufacturing technology and a sealing structure of a rotating mechanism, in particular to a plastic idler roller of an axial laminated contact / non-contact combined sealing belt conveyor. technical background [0002] Idler rollers are widely used in open-air, dusty, and highly corrosive harsh environments, such as chemical industry, metallurgical industry, cement industry, mining industry, coking industry, port loading and unloading industry, etc., while the existing belt conveyor idler rollers have The body is generally a metal or plastic pipe body, and the two ends use a labyrinth structure to prevent the erosion of harmful substances such as stolen goods, dust, and water. However, no matter which kind of labyrinth structure can effectively prevent slag, dust and muddy water from entering the inside of the idler, which will affect the normal operation of the idler and lead to early failure of the idler (the life of the idl...
