Project Description

Screw Jack

The high-speed HILBA screw jack drive was specially developed as a drive in entry assistance systems for mobile stretchers. The positioning distance of 2 meters is covered in only 15 seconds and an axial load of 1500N can be moved. The drive can be designed with a trapezoidal threaded spindle or a ball screw drive and is available with a 12/24V DC or EC motor.

Overview of your benefits.

Motors

High quality motors with 24V nominal voltage are used (12V on request). In addition to a DC motor with brushes, a brushless EC motor can also be used. The maximum load of 1500N can be achieved with both motors. Slightly higher positioning speeds are possible with the EC motor.

Accessories

The motor can be extended with a spring-applied brake E90R. This holds the load safely in its position. Magnetic and optical incremental encoders are available for position monitoring. Please note that the the magnetic incremental encoder ME80-12 cannot be installed on the EC motor. Encoder and brake can be combined.

Spindle

A ball screw drive and a trapezoidal screw spindle are available for selection. The load capacity of 1500N is achieved with both options. With the trapezoidal thread spindle, the maximum positioning speed is limited to 5 m/min. The ball screw drive is characterized by its smooth running without axial play. Both variants are maintenance-free after a one-time lubrication.

Gear

As reduction gear a modified HILBA worm gear SN25 with a maximum load limit of 8Nm is used.

Pillow Block Bearing

In order to achieve the maximum loads and positioning speeds, a locating bearing is absolutely necessary to support the spindle. We offer the EK10 pillow block bearing as an additional option.
