Ball Screw Jack

High efficiency: Ball screw jacks adopt rolling friction, compared with sliding friction, its driving torque is greatly reduced, and it can realize high-efficiency motion conversion, and the transmission efficiency can reach 90% to 98%, which saves energy and improves work efficiency.

High precision: During the movement of ball screw elevator, due to the small friction resistance, it can ensure the realization of accurate micro-feeding, and at the same time, due to the small temperature rise in the movement, it can obtain relatively high positioning and repeat positioning accuracy.

Long service life: Due to the use of high-quality materials and precision machining technology, ball screw jacks have a long service life with very high accuracy retention, and the wear and tear generated during use is very small, so the service life can be effectively extended.

Low failure rate: Ball screw jacks adopt new technology and good adjustment methods in design, which makes the equipment failure rate relatively low and ensures the stable operation of the equipment.

Good motion characteristics: Ball Screw Jacks run smoothly without chattering and crawling phenomenon, low friction resistance, can carry out precise micro-feeding control, and also can drive several same parts or devices at the same time to get good synchronization effect.

The working principle of Ball Screw Jacks is mainly based on the rolling friction of the balls between the screw and the nut. When the screw rotates, the ball rolls in the spiral groove, which pushes the nut to make a linear movement along the screw axis. Conversely, when the nut is subjected to external forces to do linear movement, will also be driven by the ball screw rotation. This kind of rolling friction transmission has the advantages of high transmission efficiency, small friction resistance, smooth movement and so on. The working principle of ball screw elevator can also be realized through the worm gear vice deceleration transmission torque, and by the screw into a linear movement of the mechanism. This kind of mechanism can withdraw the power self-locking at any position, which has the characteristics of “safe and reliable” and “small power and big thrust”. Ball screw elevator is widely used in machinery, metallurgy, construction, chemical industry, medical treatment, culture and health and other industries, powered by electricity, through the motor or hand-driven worm gear rotation, worm gear driven worm gear deceleration and rotation, worm gear cavity is processed into the internal thread, driving screw up and down movement, so as to achieve the lifting or lowering of the heavy load.

1. Lubrication: Regular lubrication of ball screws is a key step in maintenance. The use of lubricants can improve the wear resistance and transmission efficiency of ball screws. Lubricant can be divided into two categories: lubricant and grease, choose the appropriate lubricant according to the use of environment and working conditions. Lubricants are generally used in total loss systems, while greases are used in applications that require longer lubrication. Grease should be applied to the threaded raceway and the housing space where the nut is mounted, while lubricant is injected into the nut space through the oil hole in the housing. It is recommended that the grease be replaced every six months and the screws cleaned of old grease and new grease applied, or in the case of ballscrew subassemblies using lubricating oil, oiled before each machine operation.

2. Protection: Ball screws and other rolling friction transmission devices, should avoid hard dust or chips dirt into, so must be equipped with protective devices. If the ball screw sub is exposed on the machine tool, it should be protected by closed guards, such as spiral spring steel belt casing, telescopic casing and folding casing. If the ballscrew sub is in a concealed position, it can be protected by a seal. When installing, one end of the guard is connected to the side of the ball nut, and the other end is fixed on the support seat of the ball screw. Avoid touching the guard during the work, and the guard should be replaced in time if it is damaged.

3. Regular inspection: Regularly check whether the connection between the screw support and the bed is loose, whether the connecting parts are damaged, as well as the working condition and lubrication status of the screw support bearings. This helps to find and solve potential problems in time and ensure the good working condition of the ball screw.

4. Appearance and function check: The appearance of the ball screw jacks should be comprehensively inspected every month, including checking whether there are obvious scratches, dents or rust on the surface of the equipment, checking whether the connecting parts are tight, and whether there is any accumulation of debris around the equipment. In addition, a function test should be conducted to verify whether the equipment is operating normally.
