Embodiment 1

[0020] Example 1. A non-metallic material motor gear box, in which plastic raw materials and glass fiber are uniformly mixed, and the plastic raw materials are nylon or polysuccinic terephthalate, wherein nylon or polysuccinic terephthalate is combined with The ratio of the glass fiber according to the quality is 7:3; then the uniformly mixed plastic raw material and glass fiber are put into the injection molding machine for injection molding.

[0021] Select MT120 injection molding machine for injection processing, and use the following injection molding process:

[0022] 1). The heating temperature in the material box of the injection molding machine is the baking temperature of 80℃, 300℃ in the first zone, 260℃ in the second zone, 240℃ in the third zone and 235℃ in the fourth zone;

[0023] 2). Injection pressure: one section is 150 bar, time is 4 seconds; the second section is 165 bar, time is 3 seconds; three section is 90 bar, time is 3 seconds;

[0024] 3). Maintain pressure: o...

Abstract

The invention provides a non-metal material motor gearbox, comprising a gearbox body. The gearbox body is subjected to injection molding after a plastic raw material is mixed with a glass fiber; the plastic raw material is nylon or polyethylene terephthalate dialdehyde; and a mass ratio of the plastic raw material to the glass fiber is 7 to 3. The gearbox is made of plastic instead of aluminum, so that the manufacturing cost is greatly reduced. Furthermore, the plastic piece is easy to machine and produce in a large batch; and the production efficiency is improved.

Description

Technical field [0001] The invention relates to the field of motor gear box manufacturing and plastic injection molding. Background technique [0002] At present, low-power, permanent magnet DC motors are widely used in household appliances such as automobiles and fitness equipment. This kind of motor has a broad market prospect and huge demand. The motor used a gear box made of metal parts, which is generally made of aluminum. The gear box made of metal materials is not only in terms of cost, but also from the current resource saving, energy saving and emission reduction. The big social background needs to be changed. Summary of the invention [0003] The purpose of the present invention is to provide a motor gear box which is low in cost, easy to process and mass produced. [0004] To achieve the above objectives, the following technical solutions are adopted: [0005] A non-metal material motor gear box includes a gear box body, which is injection molded after mixing plastic raw...
