Automotive Engine Gear Hub PM Sintered Part

Product Introduction

Product advantages

Advantages of powder metallurgy gear hub:

1. Low cost, fast production batch, one-time molding, no need to process gear teeth after molding.

2. Due to the processing characteristics of powder metallurgy, it can be made into oil-containing parts to form lubrication-free parts, but the effect is still worse than oil bath lubrication, which belongs to the boundary lubrication state.

3. There is no waste in the forming process of the gear hub, which is better for the utilization of steel resources. The advantages of powder metallurgy gears are introduced here. In some unimportant institutions, powder metallurgy gears can be considered, such as toys, etc. Mechanical transmission, high torque transmission, etc. should be the first choice of machined gears, powder metallurgy gears. The precision is not very high, generally around 10 wires, not suitable for precision transmission. Application of powder metallurgy gear types: motorcycle oil pump: various oil pump gears, gear hubs, various oil pump rotors, cam rings, automobiles, etc.

Precautions for installation of powder metallurgy gear hub: When installing powder metallurgy high-strength alloy gear hub, it is necessary to implement the connection with the power supply according to the wiring diagram or instruction manual to avoid electric shock or fire. Do not approach or remove rotating objects (shafts, gears, etc.) when powder metallurgy good alloy gears are in operation. When debris is involved or injured, immediately cut off the power switch and deal with it in time. In addition, it should be noted that when there is a power outage, the power switch should be cut off to prevent injury or damage to the device after the power is received. Some motors in powder metallurgy alloy gears have thermal protectors. When the temperature of the motor is abnormal, the power will be cut off automatically. When the temperature of the motor drops to a certain value, the motor will automatically resume work.

What should be paid attention to when using lubricating oil for powder metallurgy gear hubs? 1. During the smearing process, use lubricating oil extrusion tool to smear, do not apply directly by hand. Since the lubrication is intermittent, a new oil film needs to be formed every time it rotates, so the lubricating oil must have a high viscosity and strong adsorption to ensure that the new oil film covers the gear surface. 2. If the neutralization price of the lubricating oil in the powder metallurgy gear cycle oiling system has increased by 0.8-1.00 compared with the new oil, and the degree of adhesion has increased significantly, it needs to be replaced immediately. 3. In addition to applying lubricating oil to powder metallurgy gears, dust-proof measures should also be taken on powder metallurgy gears to prevent dust from entering as much as possible. What are the characteristics of the strength of powder metallurgy gears? The precision of powder metallurgy gears depends on the material expansion coefficient and mold precision.

What are the problems of thermal sleeve of powder metallurgy gear parts? With the continuous development of national industrial technology, the traditional casting process of powder metallurgy can no longer meet the needs of modern industry, so the parts and products used in many fields now need to be produced by high-tech means, but powder metallurgy is this high-tech Technological craft. So what are the problems of hot sleeve of powder metallurgy wheel parts? The problems are as follows: 1. The sintering furnace (mesh belt furnace) is sintered and protected by ammonia gas. Whether it is iron-based or copper-based, it is first mixed with powder and then pressed, then sintered and shaped, and then filled with oil. 2. Carbonitriding, nitrocarburizing, induction hardening and other heat treatments can be carried out. 3. Try carbonitriding at around 850 degrees for 4 hours. The amount of kerosene should be large. It is better not to immerse the product in heat treatment first. 4. Whether carbonitriding is possible? Minxin has tested that the United States is talking about carbonitriding. 5. The sintering furnace (mesh belt furnace) is sintered and protected by ammonia gas. No matter it is iron-based or copper-based, it is first mixed with powder and then pressed, then sintered and shaped, and then filled with oil. Powder metallurgy gear surface rust prevention: passivation and coating treatment, rust prevention is still required during transportation, and coating has an impact on later assembly and use.
