What are the advantages of a ball cage cardan compared to a cross cardan?

The ball cage cardigan shaft is connected with the main shaft and the driven shaft according to the second ring of the ball cage and the star inner ring line respectively. The center of the power transmission bearing steel ball is located in the plan of the center of the shaft connecting device, and is installed in the raceway composed of the concave groove of the ball second ring road and the outer surface of the star inner ring line. The center of the two surfaces overlaps with the center of the universal coupling. In order to better ensure that the center of all bearing steel balls will be the equal surface of the intersection Angle between the center lines of the two axes, the bearing steel balls are installed in the ball cage, and then ensure that when the intersection Angle between the main and driven axes of the shaft coupling changes, the transmission support point can be located on the bisecting line of the included Angle from beginning to end. Therefore, the transmission speed between the main and driven axes of the ball cage type universal coupling is maintained at the same pace.

The transmission method of ball cage cardan shaft can be used to drive or to turn the transmission. When the drag drive is selected, in order to better cache and shock absorption, a polymer cache set 3 is installed on the ball arm and the transmitting arm. When the flip drive is selected, the genuine buffer sleeve 3 is converted into a flip part on the ball arm and the power arm. In addition, the genuine shock absorbing rubber pad is also changed into a flip part in the middle of the ball cage and the socket to integrate the rigidity of the drive.

Ball-hinged plunger pump universal coupling is a new universal coupling, which is composed of a transmission arm pair and a plate, the plate has two pieces, the stock plate surface is opened on a plurality of slots, used to connect the transmission arm pair and rolling bearings and other components, in the two plates with three of the same transmission arm pair connected, and evenly distributed in the same half of the plate. Each transmission arm pair is a telescopic joint and is accurately positioned by the limit switch 8. The power arm pair comprises a ball arm 5 and a power arm 2. The power arm is installed on the hole or slot body of one plate with the ground bolt 1, and the ball arm is installed on the hole or slot body of the other plate. The middle of the ball arm and the power arm are connected according to the ball cage and socket. There is a socket screw cap outside the socket 4 Accurate positioning.

The ball cage cardan shaft and the cross shaft cardan coupling have the following advantages:

(1) With caching, shock absorption characteristics, can reduce noise, automatic circulation system wetting;

(2) Under the same rotation diameter and inclination Angle, the bearing capacity can be increased by 0.5 to 1 times;

(3) Good synchronization, even the single ball hinge plunger pump universal coupling can also ensure synchronization;

(4) The initial compensation of axle diameter x and axial y are very large, especially the axle diameter x can be completed without the spline axis of the network part;

(5) Novel structure, light quality, good process performance, easy to mass production, cost control;

(6) Reliable in the work, convenient installation and disassembly, easy maintenance, long service life, not only low-speed light load and basic speed ratio working conditions of the shaft transmission of the universal components, but also can be used to drive at high speed. The universal coupling is widely used in many fields, especially suitable for shafting drives with large tilt angles and axial specifications subject to limited operating conditions.
