The universal drive shaft of the ball cage is connected with the driving and driven shafts respectively according to the outer ring of the ball cage and the star shaped inner ring. The management centers of the force transfer bearing steel balls are located in the plane diagram of the management center of the coupling, and are installed in the dovetail guide rail composed of the concave outer surface of the ball shaped outer ring and the star shaped inner ring. The management centers of the two curved surfaces overlap with the management center of the universal coupling, In order to ensure that all the bearing steel ball management centers will have the equal surface of the intersection angle between the center lines of the two shafts, the bearing steel ball is installed in the ball cage, so as to ensure that the force transfer point can be located on the bisector of the intersection angle from beginning to end when the intersection angle between the main shaft and the driven shaft of the coupling changes. Therefore, the transmission speed between the main shaft and the driven shaft of the ball cage type universal coupling is enough to maintain the same step.
Advantages of ball cage universal drive shaft:
1. Complete isokinetic
Because the basic principle of the equal distance reference point of the inner sports outer raceway management center is selected for the construction of the universal drive shaft of the ball cage, the complete constant speed drive system can be maintained, and the negative effects of various vibrations and impacts caused by the change of speed ratio and torque on the connecting machinery and equipment can be restrained. Due to the deviation of production and processing, the speed of ball cage universal drive shaft changes by less than 1%, while the speed of cross shaft changes by 7% when the swing angle is 20 degrees. The average speed drive system has incomparable advantages in the production and processing of metal sheet and metal surface treatment.
2. High efficiency of transmission system
The ball cage universal drive shaft has a high efficiency of the drive system, and its output power damage is similar to linear transformation within the range of shaft inclination angle transformation. When it is used, the high efficiency of the drive system can be taken as 1, and generally 0.98.
3. Compact structure, occupying small indoor space
The internal spline shaft is used to carry out the load in the mobile type, and the inner moving jacket in the load type can carry out the relative load in the radial direction; The coupling can keep the integration of load and rotation; Under the condition of equal rotation diameter, the Z short specification is much lower than that of the cross shaft.
4. Be able to absorb vibration and shock
Because the ball cage universal drive shaft can maintain rotation and load, it can digest and absorb the vibration and impact on the connected motor equipment, and the system has maintenance effect.
5. Large swing angle
The swing angle range of ball cage universal drive shaft can be from 0 degree to 42.5 degree, and bjcmz large viewing angle can even reach 75 degree. The cross axis Z is only more than 25 degrees.
6. High accuracy of rotor dynamic balance
Because of the high precision of the production of the rotating channel of the universal drive shaft of the ball cage, and all the prefabricated components are symmetrical rotators, and the strict dynamic balance test of the rotor is carried out for the high-speed shaft, the dynamic balance of the rotor of the universal drive shaft of the ball cage is of high precision.
7. Convenient installation
A. Because the two sides of the body have a certain amount of telescopic, it is very load-bearing waterproof quick loading yellow application, the installation of the cage universal drive shaft saves the cost.
B. Because the ball cage type universal coupling has a certain swing angle, the allowable deviation during installation is very large, and the pivot alignment is very convenient.
C. The novel design of flange waterproof quick installation structure shows great convenience for customers.
8. Good sealing performance
Because of the selection of sealing gasket cover, metal material sealing cover, metal material sealing sheet to maintain thorough or double-layer sealing, the cage universal drive shaft has good sealing characteristics, so as to prevent frequent maintenance and reduce labor efficiency.
9. Over voltage protection equipment
The over-voltage protection device is set on the coupling. When the transmission torque changes suddenly, the over-voltage protection device can disconnect the driving force transmission system, and has reasonable maintenance effect on all system software.
