Worm Gear Motor with Handwheel adjustment Unit

Helical Worm Gear Motor with Handwheel Adjustment Unit

 

Power Output Capacities 

The helical worm gear unit, which is adjustable via a handwheel, is made of an aluminium or cast-iron housing and is available in the following sizes: 40, 50, 63, 75, 90, 110, and 130. The combination of a helical worm gear unit, variable speed gear unit and three-phase motor is available from 0.18kW, 0.25kW, 0.37kW, 0.55kW, 0.75kW, 1.1kW. 1.5kW, 2.2kW to 3.0kW. The helical worm gear motor with speed control can be ordered with hollow shafts in the following sizes: 14mm, 18mm, 25mm, 28mm, 35mm, 42mm, and 45mm. It can also be used for mounting positions M1, M2, and M4. As with any drive of this type, care must be taken to ensure that speed control is only used during operation.


Application Examples

The SEVA-tec variable speed helical worm gear motors are used extensively, e.g. for shredders, agitators, presses, feed screws, tubular screws, dosing screws, grain crushers, belt conveyors, chain conveyors, chain scrapers, conveyor spirals, belt dryers, feed silos, washing plants, packaging machines, sawmills, for conveyor technology, the food industry, and generally in plant and machine construction.

 

Variable Speed Gear Unit – Operation Mode 

The variable speed gear unit is a planetary gear with an adjustable reduction ratio. The motor drives the so-called sun gear. The rotary motion is transmitted to the planetary gears. The connection between the stationary and the movable outer race transmits the rotary motion to the output shaft. The displacement of the spherical ring and the cam changes the axial position of the movable raceway and the radial position of the planet wheels. In this way, the roller diameter and the angular velocity of the output shaft change. If the contact point between the planetary gear and the outer raceway shifts towards the centre of the planetary gear, the output speed decreases, and the torque increases.

Speed Control – Caution

The speed may only be adjusted when the variable speed gear unit is in operation and not when it is at a standstill. Failure to do so will result in damage to the variable speed gear.

 

Helical Worm Gear Motor – Purchasing Advice

When purchasing a SEVA-tec helical worm gear motor with a handwheel speed control, professional support is indispensable. We can assist you throughout the process and help with the right product selection. Due to our large helical worm gear unit stock, we can also offer short lead times.
