Rotary Kiln Catch Wheel And Castings And Forgings For Mining Machine

1. Product description of catch wheel of rotary kiln castings and forgings

Hydraulic retaining wheel is used to control the axial movement of the rotary kiln body, so that the wheel belt and supporting wheel can be evenly worn on the full width, but also to ensure the straightness of the center line of the kiln body, so that the size of the gear meshing well, reduce power consumption.

2. Analysis of the reasons for the failure of catch wheel castings and forgings

Although there is no big fault in the hydraulic system, poor treatment may also cause kiln shutdown and production reduction. Analysis of the reasons for the failure of the hydraulic wheel system in rotary kiln:

(1) The retaining wheel is improperly installed and the surface contact is poor

When installing the retaining wheel, the center line of the retaining wheel is required to coincide with the longitudinal center line of the kiln body; Only in this way, the pure rolling friction between the wheel belt and the retaining wheel surface is ideal. Once the center line of the retaining wheel deviates greatly from the longitudinal center line of the kiln body, the friction force in the upward and downward directions will be generated on the surface of the retaining wheel, resulting in the displacement of the retaining wheel, the fracture of the upper gland bolt under excessive stress, or even the failure of the whole retaining wheel. When the retaining wheel is close to the rotary direction of the kiln body, the rotation of the wheel belt will produce downward friction on the surface of the retaining wheel, so that the thrust bearing at the bottom is overstressed and fails.

Rotary kiln, on the other hand, usually some slope when installation requirements, so the hydraulic gear wheel base also have corresponding installation Angle, such gear wheel and belting leather on the height direction of contact to reach more than 90%, and once the Angle deviation is bigger, the contact surface will appear only in the upper or lower would be less than 50% of the area, thus affecting shaft bending distance; Torque and other stress conditions cause shaft failure; The wheel belt and the retaining wheel surface due to uneven processing or wear will cause bad meshing, resulting in impact damage to the shaft.

(2) The bolts of foundation plate are too small

Generally in the design of the retaining wheel are considered to calculate and check the force of the retaining wheel and the base plate connecting bolt group, but may ignore the base plate foundation bolt checking or the safety factor is small.

3. Fault protection measures for hydraulic retaining wheel system of rotary kiln Castings And Forgings

In order to avoid similar problems in the future, we have taken corresponding protection measures based on the above analysis:

(1) Improve the existing unreasonable structure or hidden parts;

(2) Strict equipment management, improve and refine feasible operation specifications for the implementation of various projects;

(3) In the field maintenance, the management department should strictly quantify the installation technical requirements and indicators, and the construction unit should make detailed arrangements for the feasibility of the operation plan according to the requirements;

(4) Ensure that all common inspection data meet the requirements and specifications;

(5) Ensure key quality control points such as interference of shaft hole fit, comprehensive mechanical properties of shaft and surface hardness of wheel disc;

(6) Control whether each bolt reaches the required strength grade index, sealing ring performance is up to standard and other details;

(7) Strengthen the technical training for workers, do a good job in daily spot inspection and maintenance, and report any problems in time.
