Our company buffer roller manufacturing process is divided into three parts:

A, ingredients

1 axis: No. 20 with cold drawn round steel processing, deburring processing is completed, on both sides of a bearing retaining concentricity error less than 0.025mm. Www.maxmpa.com

The 2 bearing seat, the inner retainer ring, outer ring, the baffle is made up of 08F cold plate stamping, finished product may not have surface galling, rupture, crack, ground inequality defects, at the same time the need to ensure the concentricity and the outer circle

Tolerance size etc..

The 3 seal ring, the inner sealing ring, the outer sealing ring for nylon injection molding products, processing approval is required to check its there shall be no crack, burr and burr, the sealing ring should smooth, the local indentation defects shall not be big

In 0.5mm, the injection of air bubbles should not be greater than 0.5mm, per square centimeter of not more than 2, a total of not more than 5. The axial force is 1500N, the axial deformation is not more than 0.5mm.

4 roll skin: processing with Q235 steel tube.

5 bearing, retainer ring, tile for purchased parts.

6 rubber ring, industrial rubber 1260 cast, a blowhole defects, crack is not allowed. Rubber abrasion resistance and elastic.

Two, the assembly

1 roller, bearing seat is welded on both sides of the weld drum skin, the carbon dioxide welding or 1.4mm following J422 arc welding. Roller and bearing seat before welding shall be clean, and brush the inside of the skin protection

Rust paint, welding undercut phenomenon.

The 2 assembly, in the bearing oil chamber filled with butter before and after, the lithium base grease seal groove and bearing internal plus 1/2 space.

3 support roller assembly, a role for 500N in the axial pressure, roller axial displacement amount is not more than 0.7mm. The belt speed is less than 3.15m/s, the outer round roller radial runout is less than 0.7mm.

4 roller at an altitude of 1 meters of horizontal and vertical drop test, roller parts shall meet the following requirements: (1) the roller and the weld should not produce damage and crack, the matching point not loose. (2) stick

Sub axial displacement amount should not exceed 1.5mm.

5 are installed on both sides of the rubber ring, ring compression, and then welding.

The 6 assembly is completed, should be kept flexible rotation, assembly dimension in the drawing requirements within the scope of.

Installation sites of 7 weeks on either side with the grease maintenance.

Three, derusting and painting

1 remove mill scale, rust and other foreign matter.

2 exposed processing non mating surface shall be painted and dry film thickness of at least 35um.

3 primer, intermediate layer paint coating is not allowed to have a pinhole, bubbles, cracks, shedding tears, coating defects such as leakage, uniform, bright and full finish requirements.

Zhongbo industry and Mining Machinery Co., Ltd. the main products:

Ordinary, heat (high temperature), acid and alkali resistance, oil resistance, cold resistance, wear resistance, generally difficult to burn different properties of cotton canvas (CC), nylon (NN), polyester (EP) and other flat conveyor belt and the large dip angle gear sideband, pattern

Belt, and other special-shaped belt. And the roller, roller, frame, electric roller conveyor products supporting. Transmission roller; turnabout drum; electric drum; magnetic pulley (magnetic drum); idler; stent; lug; strainer;

Sweeper; coupling TD75 conveying machinery and ancillary products more than 200 kinds of.
