Problems solved by technology

[0003] During the long-term use of the gear, there is a certain force in the process of meshing with the chain or the teeth, so that the chain socket is deformed and worn.
The size is affected, it cannot work normally, and it has to be disassembled and replaced with a new one, but the manufacturing process of the sprocket and travel gear is complicated and the price is high, so welding is used to repair it

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with specific embodiments.

[0021] A method for repairing a sprocket and a traveling gear, comprising the following steps:

[0022] Step 1: Cleaning and grinding: Treat the rust and oil stains on the surface of the dismantled sprocket, and use a grinder to remove the oil stains and rust on the surface until the surface reveals a metallic luster;

[0023] Step 2: Inspection and detection: Use an ultrasonic flaw detector to detect internal flaws on each chain tooth. If there are cracks or other defects on the chain teeth, use carbon arc gouging to remove them to ensure that each chain tooth has no internal defects, and then Use coloring flaw detection agent to carry out coloring flaw detection on the surface to remove the pores on the surface for the next step of welding;

[0024] Step 3: Bottom welding: use the welding method of manual arc welding for bottom welding to ensure the welding qua...

Abstract

The invention provides a repairing method of a chain wheel and a travelling gear. The method comprises the steps of 1, cleaning and grinding; 2, detecting and performing flaw detecting; 3, bottoming welding; 4, filling welding; 5, removing welding margin; 6, thermally processing; 7, assembling the repaired chain wheel on a device to use. With the adoption of the method, the repaired chain wheel and travelling wheel can be continuously used, and a certain service life is ensured; the method is low in cost, good in use effect, and convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of repair methods, in particular to a method for repairing sprockets and travel gears. Background technique [0002] Sprockets and travel gears are widely used in mechanical transmission in chemical industry, textile machinery, food processing, instrumentation, petroleum and other industries. During use, it must be ensured that the energy-saving chain enters and exits meshing smoothly and freely, minimizes the impact and contact stress of the chain links during meshing, and is easy to process. [0003] During the long-term use of the gear, there is a certain force in the meshing process with the chain or the teeth, so that the chain socket is deformed and worn. The size is affected, it cannot work normally, and it has to be disassembled and replaced with a new one. However, the manufacturing process of the sprocket and travel gear is complicated and the price is high, so welding is used to repair it. The r...
