What should be paid attention to when selecting screw jack ?

图片
When selecting screw jacks , we should pay attention to the following questions . 1. The capacity load of the screw jack. Whether it is static load, dynamic load, or impact load , can not exceed the maximum load allowed to bear. 2.The speed ratio of the screw jack. The speed ratio of the screw jack is generally divided into normal and slow speed, which needs to be determined according to the actual use. 3. T he connection mode between the jack and the motor . The connection type has the flange direct type and the biaxial type. 4. C ondition s and working time of the screw jack . The surface temperature should be controlled within the range of -15 ° ~80 when running the jack . When the ambient temperature is lower than 0 ℃ , the efficiency of the whole machine will decrease due to the change of the viscosity of the lubricating oil, so it is necessary to select a sufficient driving source.

How much do you know about the ball screw jack

Ball Screw Jacks use a ball screw and nut made from hardened alloy steel with hardened bearing balls carrying the load between nut and screw.This rolling action reduces friction between the nut and the screw permitting smooth and efficient movement of the load. The difference between a ball screw jack and a machine screw jack is  that it uses a high precision ball screw. The ball screw can be used in a wide range of applications. The ball screw has high precision, low pollution, long life and high speed forward reversal. Therefore, it has become a standard accessory in the field of precision machinery in recent years. The ball screw is used on the lift to help the screw jack have higher positioning accuracy, lower noise, faster speed and a significant increase in efficiency. Therefore, the ball screw jack is more suitable  in high-speed high-frequency environments. The ball screw jack, whose thermal expansion  prone to cause a decrease in accuracy ha

Non-rotation Screw Jack with Square Tube

For translating screw jacks , key-way is a common way to realize the anti-rotation for the screw jack.In fact, there is another way,that is to use a special square tube. A square guide tube is attached to either the top or bottom of the Screw Jack. A square bronze nut is attached to the end of the Lifting Screw which is then fitted inside the tube, preventing rotation. Application: Mostly used on larger Jacks and where the lifting load is high in relationship to the Nominal Capacity or where the travel is long. Please note input torques required will increase by approximately 8%. Now let's see a video about the non-rotation screw jack with square tube. Welcome to visit https://www.ludetransmission.com/

Screw Jack Lifting Systems for Crank Table

As a professional high-end automated processing equipment company in screw jack lifting system, Ludetransmission supply a complete lifting solutions for crank table, including screw jacks , cast iron crank handles, couplings and connecting shafts. Following your design technical parameters like table sizes, loads, lift height etc, our engineers will select the correct models of above products. At present, we offered 1 ton screw jack mechanism , 2.5 ton screw jack mechanism , and 5 ton screw jack mechanism for table building customers. According to the table size, 2-set screw jack mechanism/3 -set screw jack mechanism/4- -set screw jack mechanism are optional. With the crank table loading capacity,lifting height,distance between screw jacks , we can give customers whole solution.When loading capacity is big, the guide support will be suggested. Because screw jacks are designed primarily to raise and lower axial loads and any side loads should be avoided. The jack

Electric Screw Jack Lifting System

According to detailed need, Ludetransmission can choose multiple screw jacks to make up a screw jack system .The system can be of different screw jack arrangements ,like I/T/H/U type etc. When multiple screw jacks are used as a whole screw jack system, we suggest to choose one electric motor to drive all screw jacks. In this way, the s ynchronism can be guaranteed. Or, the rotation speed of different motors will have error,so it may cause the operation of the lift to be out of sync.

Application Areas and Advantages of Small Screw Jacks

图片
Application areas : The mini screw jacks are widely used in chemical metallurgy, machinery manufacturing, door and window lifting, three-dimensional garages, and all places involving workpiece displacement. In recent years, the application fields are more extensive, such as some welded pipe equipment, glass machinery, flattening machine slitting machine, 3D printing equipment and other industries.  The small screw jack is more and more favored by the majority of manufacturers. Advantage: Compared with the hydraulic lift, the worm gear structure has its own unique advantages, small size, the general hydraulic lift is bulky and bulky, and the worm gear screw jack is relatively small in size, beautiful in appearance and convenient to install. It can be safely self-locking, hydraulic lift only plays the role of “pressure”, can not control self-locking, and the worm gear screw lift can be safely self-locking, no need to worry about the trouble caused by power fail

How often should I change the oil in the gearbox?

Usually Lude bevel gearboxes are filled with gear oil for normal operation before leaving the factory and are ready for use.The standard gear oil is HD320~680. Notes:Delivered gearboxes by air/express without gear oil.To prevent the gearbox leak,we do inject gear oil to inspect them,after that, exhaust the gear oil before shipment. Normal working conditions, after 300 work hours, first time to inject grease. After that,each time per 1500 work hours. Lude spiral bevel gearboxes
