Problems solved by technology

However, the gears produced by traditional machining methods generally have the problem that tooth surface burrs and edges are difficult to eliminate, and the noise caused by tooth surface burrs and edges to high-speed gears is very obvious, which seriously affects the quality of products.
There is no better way to eliminate this noise in the prior art, and it is very difficult to remove the burrs and edges of the gear tooth surface

Embodiment Construction

[0019] Such as figure 1 , figure 2 with image 3 Shown, put semi-fluid mortar 1 in container 5. Semi-fluid mortar 1 is made of emery, paste-like bonding material (such as flour paste), sodium nitrite and water; wherein the weight proportion of each component is emery 80%, flour paste 5%, Sodium Nitrite 1% and Water 14%. Then, the gear 2 is fixed on the shaft of the motor 4 , and the gear 2 is completely submerged in the semi-fluid mortar 1 . figure 1 Middle 3 is a bearing seat.

[0020] The starter motor 4 drives the gear 2 to rotate at a high speed in the semi-fluid mortar 1, so that the tooth part of the gear moves relative to the corundum to ensure that the linear speed of the tooth part is more than 4 meters per second, such as 5 meters per second. In this way, the corundum collides with the gear teeth at high speed, and the corundum will grind the gear teeth, and the smoother the gear surface, the smaller the resistance, that is, the less the grinding effect of the ...

Abstract

The invention discloses a method for flexible grinding and processing of gears, that is, high-speed collision between gear teeth and semi-fluid mortar, so that the semi-fluid mortar can grind the gear teeth; the gear rotates at high speed in the semi-fluid mortar, and the The linear speed of the gear tooth section is at least 4 meters per second. The invention applies the principle of fluid mechanics, that is, when the fluid flows along the solid surface at high speed, the smoother the solid surface, the smaller the resistance, that is, the smaller the grinding effect of the diamond on this part; When the fluid mortar moves relatively at high speed, the resistance is very large, that is, the emery has a great grinding effect on the part, and the burrs and edges are quickly ground off. The core of the present invention is to grind the smooth part (such as the tooth surface part) of the gear in a small amount, and quickly grind the burrs and edges. The present invention is suitable for most products of machinery manufacturing category.

Description

technical field [0001] The invention relates to a processing method for removing burrs and edges of a gear tooth surface, in particular to a method for flexible grinding and processing a gear, and belongs to the technical field of mechanical processing. Background technique [0002] With the rapid development of today's technology, the requirements for the speed of gears are getting higher and higher, and the requirements for the accuracy of gears are bound to be higher and higher. However, the gears produced by traditional machining methods generally have the problem that tooth surface burrs and edges are difficult to eliminate, and the noise caused by tooth surface burrs and edges to high-speed gears is very obvious, which seriously affects the quality of products. There is no better method in the prior art to eliminate this noise, and it is very difficult to remove burrs and edges on the gear tooth surface. Contents of the invention [0003] In view of the above-mentio...
