Ball elevator snb50t electric hand screw lifting machine

  SNB screw lifter is characterized in that the ball nut is placed in the shell, uses ball screw and nut, is made of hardened alloy steel, and carries the load between the nut and screw
This rolling action can reduce the friction between the nut and the screw rod, so as to make the load move smoothly
Due to the improvement of working efficiency and rolling performance, compared with the ordinary trapezoidal screw elevator, the ball screw can be operated at a higher speed or in a larger working cycle
High precision screw elevator is suitable for panel factory industries such as stainless steel precision plate and wafer
It can save space, improve high precision and high speed, and greatly improve the output

The service life of ball screw elevator series products is mainly determined by the service life of ball screw, worm gear and other parts; We mainly check the service life of the ball screw
The worm gear and worm will be worn, but the service life is generally longer than that of the ball screw
This elevator is mostly used in the environment with high accuracy requirements and high-precision automation equipment

The working principle of the brake of the ball screw elevator is: one group of the brake friction pair is connected with the fixed frame; The other group is connected with the rotating shaft of the mechanism
When the friction pair contacts and compresses, it will produce braking effect; When the friction pair is separated, the braking effect is released and the mechanism can move

According to the working state, the brake of ball screw elevator can generally be divided into normally closed and normally open

1
Normally closed: when the mechanism is in non working state, the brake is in closed braking state; When the mechanism works, the operating mechanism automatically releases the brake first
The hoisting and luffing mechanisms of tower cranes are normally closed

2
Normally open: the brake is usually released, and it is completed by mechanical or hydraulic mechanism when braking is required
The slewing mechanism of the special reducer for tower crane and construction elevator adopts normally open type

According to different structures, the brakes of ball screw elevator can be divided into the following three categories:
1
Belt brake: the braking torque is generated when the braking steel belt surrounds the braking wheel in the radial direction

2
Block brake: two symmetrically arranged brake pads produce braking torque by holding the brake wheel radially

3
Disc and cone brakes: disc and cone metal discs with friction lining are close to each other in the axial direction to produce braking torque

Application scope of ball screw elevator:
1
Lifting, displacement, clamping, turnover and other actuators in the production line
2
Devices and clamping, lifting and turnover devices in metallurgical equipment
3
Car lift, flexible tooling and welding elevator in vehicle manufacturing industry
4
Lifting device and solar power generation device of monocrystalline silicon and polycrystalline silicon ingot furnace in photovoltaic industry
5
Aerospace, astronomical telescope and other remote control actuators
6
Stage lifting device
7
Various actuators of shipbuilding, water conservancy, food, warehousing, casting and other industries, woodworking machinery and food machinery 8 The lifting devices on machine tools such as vertical lathe and gantry are suitable for devices with high speed, high frequency and high performance
The main components are precision ball screw pair and high-precision worm gear pair

High efficiency: only a small driving source can produce a great driving force
High speed: compared with trapezoidal screw rod, the speed is greatly improved and can operate easily and at high speed
Long service life: high quality ball screw is adopted to increase its service life by more than 3 times
