DKG(J) Ball Screw Spline & Large Heavy Ball Screw

DKG(J) Ball screw spline

The ball screw and Ball screw spline is a new type of compound developed for the application field of automatic and intelligent production line with rolling function parts, the products are widely used in horizontal multi-joint robot (SCARA) Z axis, glue dispenser, welding machine, automatic loader, automatic testing equipment and machining center ATC (automatic tool change) and other rotating motion and straight mechanical combination device for linear motion.

Products are mainly composed of hollow screw spline shaft, ball nut rolling bearing compound unit, spline sleeve rolling bearing aseembly unit and other components.

Compound:

The ball screw spiral raceway and ball spline (straight) raceway are cross-designed on the same shaft, and the ball nut and spline sleeve are respectively integrated with the rolling bearing height. Through the rotation or stop of the ball nut and spline sleeve, the ball spline shaft can be rotated, straight and spiral in 3 forms of compound movement.

● Lightweight, low inertia:

Ball screw spline shaft adopts hollow design, the overall weight is light; The ball nut and spline sleeve are integrated with the bearing design, making the radial size of the ball nut rolling bearing compound unit and the spline sleeve rolling bearing compound unit small enough and the moment of inertia extremely low.

● High speed, low noise:

Ball screw selection of large lead design, coupled with the rotating unit moment of inertia is very low, low noise at high speed movement.

● Easy to install:

The two ends of the ball nut rolling bearing composite unit and spline sleeve rolling bearing composite unit are provided with standard driving pulley connecting parts, which is convenient for user selection and easy installation.

Large heavy ball screw

Applications:

It is widely used in large-scale gantry boring and milling machine, composite machining center, aerospace, large machinery lifting equipment, large ship locks, forging equipment, metallurgical equipment, hydraulic equipment, large aircraft ships, large power generation equipment and other fields.

Introduction of Product design, manufacturing and testing technology:

Length and heavy load have always been an important problem to be solved in the manufacture of large and heavy load type ball screw. This series of products have conquered the design, heat treatment, straightening, thread way forming and dynamic detection technology. In the structural design, the product adopts the design structure with multi-path and large diameter ball cycle circuit, with the maximum rated dynamic load rating of 126 tons and the maximum static load rating of 595 tons. 

Nanjing Technical Equipment Manufacture Co.,Ltd. has put into use a series of equipment, such as 10 meter large lathe, 10 meter hard milling machine, 10 meter large grinder, 10 meter medium frequency quenching machine, 10 meter large straightening machine, 10 meter laser measuring instrument for stroke accuracy and so on, taking the lead in establishing the first single 10 meter ball screw production line in China. Especially,the 10 meter laser measuring instrument for stroke accuracy has passed the calibration of Jiangsu Institute of Metrology and has been put into use. It solves the key technology in the dynamic detection process of a single 10 meter ball screw pair. 

The industrialization base of large and heavy load ball screw pair has been established.
