Helical parallel shaft geared motor

Helical parallel shaft geared motor are the modern version of coaxial geared motors. As a result of their compact and short design, they take up less space than helical geared motors. Helical parallel shaft geared motor can either have a solid shaft - or alternatively a hollow shaft as so-called plug-on gear unit. This means that the geared motor is optimally integrated into the driven machine. Additional components - e.g. such as gear wheels or chain wheels - to transmit the force to the driven machine are eliminated. Helical parallel shaft geared motor represent the space and weight-saving solution within the range of coaxial geared motors.

higher ratios for dynamic oil gearbox

dynamic oil gearbox ,the maximum torque, speeds, and radial loads published cannot be used simultaneously. Proper service factors must be applied to accommodate a wide range of dynamic applications. And, once the appropriate speed reducer is selected, proper installation and maintenance are the keys to maximizing life.

Paper mill gearbox offer compact designs in higher ratios, while helical and spur reducers are generally the most economical. All are fairly efficient.

A greater transfer of torque of worm gear efficiency

worm gear efficiency ,They are similar in appearance to spiral bevel gears and again have a helical tooth form. However, the pitch surface is a hyperboloid and the axes of the gear system do not intersect. This axial offset places a hypoid gear set geometry between that of a worm and a bevel gear set and therefore displays a combination of their characteristics. I.e. like a worm gear set it can transmit a large torque and, like small bevel gearboxes, it can run very smoothly with little noise or vibration. The more closely it resembles a bevel gear set, the higher the efficiency due to less losses through a lower sliding contact between the teeth. The positioning of the hypoid gear implies that multiple teeth mesh simultaneously thus sharing the load over a larger surface area and allowing for a greater transfer of torque.

Applications of speed increaser gearbox

speed increaser gearbox are able to withstand high shock loads, low in noise level and maintenance-free but are less efficient than other gear types. Worm gears can be used in right angle configuration. The worm gearbox configuration allows the worm to turn the gear with ease; however, the gear cannot turn the worm. The prevention of the gear to move the worm can be used as a braking system. When the worm gearbox is not active, it is held in a locked position.

Tork Drive worm gear efficiency

Tork Drive  worm gear efficiency :

Reduce Energy Consumption and Energy Costs

If you have an application that does not need to be run at full speed, then you can cut down energy costs by controlling the motor with a variable frequency drive, which is one of the benefits of Variable Frequency Drives. worm gear box allow you to match the speed of the motor-driven equipment to the load requirement. There is no other method of AC electric motor control that allows you to accomplish this.

Tork Drive ensuring optimal motor application speed. Because of the worm gear box​ optimal control of the motor’s frequency and voltage, the VFD will offer better protection for your motor from issues such as electro thermal overloads, phase protection, under voltage, overvoltage, etc.

equation to calculate efficiency of worm gears

worm gear. In these widely used speed reducers, a worm gear drives a worm wheel to provide output motion at a right angle to the motor shaft . 

 These speed reducers are often the best value for applications in which the motor and reducer are coupled in-line with the driven shaft, Figure 5. Their efficiency usually ranges between 95 and 98%, regardless of speed ratio. Cost is competitive with worm gear motor where the center distance is 2-in. or more.

The worm gear and worm wheel have non-intersecting, perpendicular axes, and the meshing action between gears occurs over a relatively large contact area. This meshing action consists primarily of a sliding motion that creates friction between the gears.

Worm gear efficiency varies significantly when lead angle, friction factor and gear ratio changes.
