Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0028] The invention provides a method for repairing a sprocket with broken teeth, which is used for repairing the unusable sprocket due to broken teeth. This method comprises the steps:

[0029] Step 1 S110: Obtain the size parameter and material of the sprocket.

[0030] The size parameters of the sprocket, including the profile of the tooth shape, can be obtained according to the sprocket model, drawings and other information, so that the repaired sprocket can meet the size requirements. As a preferred option, in many cases, the sprocket has broken teeth after a long period of use, and the original drawing of the sprocket cannot be found. This requires surveying and mapping to obtain the outline of the sprocket teeth. Usually, a three-coordinate meter or a projector can ...

Abstract

The invention discloses a method for repairing a broken tooth chain wheel. The method comprises the following steps: step I, acquiring a dimension parameter and a material of the chain wheel; step II, polishing a broken tooth position; step III, preheating the broken tooth position to 300 to 400 DEG C and performing heat preservation; step IV, preheating a welding rod to 300 to 400 DEG C, and setting current of a welding machine to 80 to 100 A, performing repair welding on the broken tooth position of the chain wheel, and enabling the part after repair welding to cover an original chain wheel tooth part and making machining allowance; step V, performing annealing treatment on the chain wheel after repair welding; step VI, performing flaw detection on a repair welding part of a broken tooth, if a flaw appears, removing the flaw part by using carbon arc gouging, and repairing the flaw part by using steps II to V; and step VII, machining the contour of the repair welding part into a wheel tooth size by using a machining mode. According to the method for repairing the broken tooth chain wheel provided by the invention, the repair welding part and the chain wheel body have high fusibility; the whole chain wheel is prevented from being changed by separate repair on a chain tooth, so that cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of sprocket repair, in particular to a method for repairing a broken-tooth sprocket. Background technique [0002] Chain drive is a transmission method that transmits the movement and power of the driving sprocket with special tooth shape to the driven sprocket with special tooth shape through the chain. Chain transmission has many advantages. Compared with belt transmission, there is no elastic sliding and slipping phenomenon, the average transmission ratio is accurate, the work is reliable, and the efficiency is high; the transmission power is large, the overload capacity is strong, and the transmission size is small under the same working conditions; the required tension The tightening force is small, and the pressure acting on the shaft is small; it can work in harsh environments such as high temperature, humidity, dust and pollution. The average transmission ratio of the chain transmission is accurate,...
