How To Choose The Hydraulic Pump Drive Shafts
2016-08-07
There are so many factories for hydraulic pump drive shaft. Some of them are only small workshops that they machine by themselves. So the quality of the pump drive shafts and shafting hangers from different factories are far different. How to choose the good quality mixer truck propeller shafts? The best way is to choose the the shafts made from medium carbon steel material. The reasons are as follows:
1. Low carbon steel is flexible, but not strong enough. It's easy for welding and cold stamping so it is suitable for casting many standard parts, bushings and containers.
2. High carbon steel is strong, but not flexible, uneasy for machining. So if it is used for producing shafts, it's not flexible enough and easy broken. It's better for producing the static pressure,wear resistance parts, such as heavy rail,rollers. After heat treatment, it can be for producing springs, wire rope which needs high strength and high wear resistance.
3. Mixer truck hydraulic pump drive shafts, shafting hangers are used for supporting the solid of revolution and power transmission. When they are working, they will be under the friction and damage from the alternating torque and tensile and compressing load of the shaft neck and shaft key. It's working failure normally because of the breakage or cracking or parts' wear out. The breakage includes fatigue breakage and overload breakage. So when choosing the material, the material must be with high strength, flexible enough, with good wear resistance,with good endurance and easy for machining. Thus the shafts can be with the good comprehensive mechanical properties.
4.Medium carbon steel after heat treatment (tempering, surface hardening, carburization) can be with the good comprehensive mechanical properties. And it can be made for the parts with good internal strength and exterior wear-resistance.
