Problems solved by technology
Because the cross shaft has four shaft ends, it is difficult to refuel evenly when refueling. When the transmission shaft is under high load, the steel bowl of the cross shaft will heat up and burn the oil seal, resulting in failure of the cross shaft and affecting the normal use of the transmission shaft.

The invention relates to a roll ball type transmission shaft. The roll ball type transmission shaft comprises connection head components arranged at the two ends and a stretching and contracting transmission component for connecting the connection head components located at the two ends, wherein each connection head component comprises a connection head shell, a connection head fixing shell, rollballs and a moving connection head, the connection head fixing shells are arranged at one ends of the corresponding connection head shells, the moving connection heads are rotatably arranged inside the corresponding connection head fixing shells, and the roll balls are arranged inside the corresponding connection head fixing shells and jack the corresponding moving connection heads. The roll balltype transmission shaft has the beneficial effects that because of the above structure, the transmission shaft can save the cost effectively under the situation of not affecting the function and the product performance, oil filling mouths directly face the positions of the moving connection heads, effective lubrication can be achieved, and the product service life is prolonged.
Description
technical field [0001] The invention relates to a universal mechanical transmission device, in particular to a ball type transmission shaft. Background technique [0002] The middle of the conventional agricultural transmission shaft yoke is connected by a cross shaft to achieve the function of universal rotation. Because the cross shaft has four shaft ends, it is difficult to refuel evenly when refueling. When the transmission shaft is under high load, the steel bowl of the cross shaft will heat up and burn the oil seal, resulting in failure of the cross shaft and affecting the normal use of the transmission shaft. Contents of the invention [0003] In order to effectively solve the above problems, the present invention provides a ball drive shaft. [0004] The technical solution of the present invention is as follows: a ball-type transmission shaft, comprising: connector assemblies arranged at both ends and a telescopic transmission assembly for connecting the connector...
