Embodiment Construction

[0015] A method for manufacturing a speed-adjusting three-jaw ring gear includes the following steps:

[0016] Step 1: Proportioning metal powder, weighing 90 parts by weight of iron powder, 2 parts by weight of nickel powder, 1.5 parts by weight of copper powder, 0.5 parts by weight of molybdenum powder and 0.6 parts by weight of sintering aid, the sintering aid The agent includes 0.3 parts by weight of cuprous phosphide powder and 0.3 parts by weight of ferric oxide powder, and the powders weighed are mixed uniformly to form powder metallurgy powder, which is reserved for later use;

[0017] Step 2: Compression molding, filling the powder metallurgy powder in step 1 into the mold set, the mold set includes a middle mold fixed on the workbench, a lower mold attached to the bottom surface of the middle mold and powder metallurgy The powder is pressed into the upper mold in the space formed by the middle mold and the lower mold. The middle mold includes a horizontally arranged ...

Abstract

The invention relates to a manufacturing method of an adjustable-speed three-jaw inner gear ring. The method comprises the following steps that firstly, metal powder is proportioned; secondly, compression moulding is performed; thirdly, sintering of the three-jaw inner gear ring is performed; fourthly, carburizing treatment of the three-jaw inner gear ring is performed; fifthly, tempering of the three-jaw inner gear ring is performed; and sixthly, grinding and packaging are performed. The method is scientific and precise, the strength and comprehensive mechanical performance of gear teeth of the three-jaw inner gear ring are improved, the torque transmission capacity is improved, the bearing capacity of convex jaws is improved, and the service life of the three-jaw inner gear ring is prolonged.

Description

technical field [0001] The invention relates to the technical field of ring gear manufacturing, in particular to a method for manufacturing a speed-regulating three-jaw ring gear. Background technique [0002] In the current industrial production and daily life, electric hand drills can be seen everywhere, but the speed-regulating three-jaw inner ring gear used on the hand-held drill is difficult to access. Common speed-regulating ring gears are metal castings or plastic castings or traditional cutting process. Its shortcomings are: the mechanical properties of castings and traditional cutting parts are poor, the internal structure of the material is loose, the mechanical strength of the product is poor, and tooth damage is prone to occur, and the utilization rate of traditional cutting metal materials is low, and the production efficiency is low. Low. Contents of the invention [0003] The object of the present invention is to provide a method for manufacturing a speed-...
