Shanghai Jianping congratulates SAIC Motor on winning the top domestic automaker for six consecutive years. Jianping will continue to provide support for SAIC Motor's development.
Introduction to the differential
You may be a little curious, what kind of help can Jianping provide for SAIC Motor? Next, we will explain to you. Let take the differential case in the power transmission system as an example.
The differential is a relatively unknown car component, its name is very strange, differential? Why is it called a differential? How did the differential come from? Where it is used in the car? Here we will lead you to understand the differential and the differential case balancing machine.
The power of the automobile engine is transmitted to the drive axle through the clutch, transmission, and drive shaft, and then distributed to the half-shaft drive wheels on the left and right sides. In this power transmission path, the drive axle is the latter assembly, and its main components are the reducer and differential. The function of the reducer is to decelerate and increase the torque. This function is completed by the meshing between the gears, which is easier to understand. The differential is more difficult to understand, what is a differential? and why is it "differential"?
The ordinary differential of an automobile is composed of planetary gears, planetary carrier (differential case), half-shaft gears and other parts, which can make the left and right (or front and rear) driving wheels rotate at different speeds.
When the car turns, the turning radius of the inner wheel and the outer wheel is different, and the turning radius of the outer wheel is larger than the turning radius of the inner wheel, which requires that the rotation speed of the outer wheel is higher than that of the inner wheel when turning. The function of the differential is to meet the different requirements of the wheels on both sides when the car turns! This function is the basic function of the differential. As for the latecomers' anti-skid differential, LSD differential, Torsen differential, etc., they are designed to improve the driving performance, handling performance and safety performance of the car.

The differential case automatic balancing machine is used for single-plane automatic unbalance correction of disc-shaped workpieces, it adopts the new technology of Shanghai Jianping dynamic balancing machine. The differential cases are automatically done from unbalance measurement, angle positioning, milling weight removal and retest. It has the characteristics of high speed and high precision, and is suitable for mass production of differential case dynamic balancing.
Screenshot of GRR (Repeatability & Reproducibility) report
The full English name of GRR is Gauge Reproducibility and Repeatability, which is a test to measure the variability and reproducibility of equipment. The purpose of GRR is to reduce the measurement error and make the measurement values as close as possible.
This Differential Case Automatic Balancing Machine is one of the best-selling models of Shanghai Jianping. This balancing machine has complete and mature technology; the correction of workpieces from unbalance measurement, angle positioning, to drilling weight removal and retest is not only fully automated; but also has the characteristics of simple operation, convenient application and high precision; Very suitable for small and medium batch production. Such a fully automatic balancing machine tailored for the differential case, of course you deserve it!
