Product description

Friction self-aligning roller roller is mainly based on DTII selection manual, two tapered rollers are mounted on their respective Rotary shaft,two rotary frame through the connecting rod mechanism to achieve synchronization,beams directly connected to the middle frame,tape deviation after driving the Rotary frame around the Rotary shaft rotation angle.At this point the self-aligning roller is applied to the tape lateral thrust Fn, prompting the tape after deviation return in situ,to achieve automatic correction deviation tape,tape to ensure that the operation.Which is characterized by the original forward aligning groove roller into a tapered roller, due to the different diameters at both ends of the tapered roller, so that when the roller is rotated, the roller size of the head in contact with the tape at the line speed is different, there is a speed difference, thereby changing the force condition of the roller,Since the tapered self-aligning roller two rotary shaft is separated, the Rotary shaft strength is weak, the Rotary shaft bending phenomenon occurs when a large amount of transport, in addition to promote two rotary frame to achieve synchronization of the link mechanism, due to a variety of factors such as manufacturing, installation and other synchronization effect is not ideal, the impact of automatic self-aligning effect.

The use of friction self-aligning roller has many characteristics：

1、Friction self-aligning roller bearing position at both ends of the different axes is less than 0.05 mm, the outer radial runout is less than 0.3 mm, the rotational resistance is less than 1N, the quality of the rotating part of the reduction of 13, it is possible to make the conveyor parts to achieve long transport distance, large transport, high-speed operation work.

2、Friction self-aligning roller and roller package tape between the basic realization of the synchronous operation, wear between each other is very small, extended; tape and drive rubber roller service life.

3、Roller steel wrapped tire rubber layer, its anti-corrosion and rust greatly improved, farewell to the traditional roller weight,low accuracy, resistance, not easy to damage the era, and passed the lifting and transport machinery Quality Supervision and Inspection Center type test recognition and coal mining machinery Quality Supervision and Inspection Center safety standard inspection, made a mark.

Friction self-aligning roller has a strong ability to prevent damage and deviation of the conveyor belt,the use of frictional resistance and friction wheel curvature deviation mechanism to prevent and correct deviation of the conveyor belt, to achieve self-aligning effect.Friction roller is mainly widely used in metallurgy, chemical industry, coal, building materials and other industries.Friction roller using standard design, manufacturing technology,the design and manufacture of the roller to a high level, the production of the roller has a small rotational resistance, long life, small maintenance workload and high carrying capacity.Steel pipe using roller special high-frequency welded pipe,the pipe to do thorn treatment, roundness control within a special tolerance range.The shaft is made of cold drawn steel machined to standard tolerances.The bearing housing is made of cold-tie steel plate stamped by several processes.The roller housing and the housing are welded together by an automatic welding robot to form an integral structure with a high strength.Friction self-aligning roller according to its use is classified as self-aligning roller, buffer roller, trough roller, parallel roller.The role of self-aligning roller is to correct the deviation of the belt conveyor, usually installed on the heavy-duty section of the conveyor Rotary groove self-aligning roller, install Parallel self-aligning roller on the no-load section.Buffer roller is applied to the tail frame according to the actual situation, when the material, can reduce the impact of the material on the belt, is conducive to the service life along the long belt.Groove roller generally consists of two side rollers and a flat roller composition, groove angle is generally 30 degrees, for removable belt conveyor, groove roller three rollers hinged to each other together, so called hinged roller.Parallel roller is generally a long roller, which is mounted on the lower end of the pressure so called under the roller.
