BOYA's ball cage transmission shafts are widely used in the field of electric and diesel drives for oil drilling and production. The cv ball joint used are fracturing skids, pumping machines (commonly known as kettles), workover machines, drilling rigs, cementing machines, mud pumps, turntables, winches, oil special vehicles, etc. In response to the characteristics of petroleum equipment that cannot be easily adjusted and moved, BOYA has developed BHJ-F and BHJ-E ball cage drive shafts that are highly durable, short, and easy to install and replace.
Also for the short distance, high speed, installation error and angular error compensation function of the power transmission characteristics of petroleum machinery, BOYA cv ball joint developed the BJS ball type cv joint of short drum gear drive shaft upgrade products, this type of product running smoothly, compact structure, high load capacity, large angular compensation, generally up to 5 °, easy installation and adjustment characteristics. In addition, the two outer rings of the BJS type drive shaft mesh with each other through the end teeth, reducing the shearing force of the coupling bolts and effectively preventing the bolts from loosening due to vibration.
BHJ-E ball cage drive shafts with high durability, short form and easy installation and replacement. At the same time, in view of the petroleum machinery short distance, high speed and angle to the installation error and error compensation function of power transmission characteristics,BOYA, one of metal processing machinery manufacturers developed a BJS type of short drum gear transmission shaft, an upgraded version of this type of products smooth operation, compact structure, high bearing capacity, angular compensation amount is large, generally can be up to 5 °, convenient to install, etc. And the BJS type drive shaft on both sides of the outer ring through the end teeth meshing each other, reducing the shear force of the connecting bolt, can effectively prevent the phenomenon of bolt loosening caused by vibration.
