higher torque applications of the planetary gearbox

brevini gearbox speed adjustments are easily made by moving a lever control through an arc or turning the hand-wheel of a screw type control. In either case, easy and precise speed control settings are possible with Zero-Max adjustable speed drives - also referred to interchangeably as variable speed drives.

ball mill gearbox ,For lower speed/higher torque applications, some Zero-Max drives are available with our right angle gearbox. Some Zero-Max drives may be purchased with standard electric motors or they may be connected to any rotating power source up to 2000 RPM. 

High speed planetary gearbox

The high speed planetary gearbox is a transmission with a planetary gear. The high speed planetary gearbox is usually mounted on the back of the hydraulic torque converter to form the hydraulic automatic transmission. The planetary gear mechanism is named for its resemblance to the solar system. At its center is the solar wheel, which is surrounded by several planetary wheels that revolve around it. On the outside of the planetary wheel, there is a big toothed ring.

high-ratio of the NMRV worm geared motor

NMRV worm geared motor and worm gears provide an effective answer for power transmission applications requiring high-ratio speed reduction in a limited space using right angle (90°), non-intersecting shafts. When properly applied, worms and worm gears provide the smoothest, quietest form of gearing.

worm gear efficiency of a worm gear drive depends on the lead angle and number of starts on the worm - and because increased efficiency is always a goal, the ratio should be kept as low as possible. To run properly, worms and worm gears used together must have the same diametral pitch and threads.

speed increaser gearbox to increase energy efficiency

speed increaser gearbox is possible to significantly increase gearmotor efficiency by replacing a permanent split capacitor (PSC) ac motor with a permanent magnet dc (PMDC) motor. PSCs may have greater maximum efficiency potential, but their true efficiency can be much lower at the actual application operating load point. Also keep in mind that three-phase driven gearmotors are much more efficient than the single-phase equivalent (for example, 64% vs. 53%) and are more reliable because of their simplified design. However, when three-phase power is unavailable, a High Efficiency Vf  Worm Gearbox is required to convert single-phase input to three-phase output for the gearmotor. Today's VFDs are economical and easily justified when one considers their built-in features, such as soft starts to reduce mechanical shock and increase equipment life.

Higher efficiencies of worm gear efficiency

worm gear efficiency - Comparing efficiencies of different gear types across various reduction ratios will help us to make right gearbox selection for our applications. Spur gearing is a parallel shaft arrangement, and these gears can achieve much higher efficiencies compared to other gear types. The worm gear motor is efficiency varies from 94% to 98% with lower gear ratios. Straight bevel gearing is similar to spur gearing with perpendicular shaft arrangement. Like spur gearing these gears also only can handle lower gear ratios with higher efficiencies (93% to 97%).  

Planetary gearbox efficiency

planetary gearbox efficiency , Power losses in gear systems are associated primarily with tooth friction and lubrication churning losses.    Churning losses are relatively independent of the nature of the gears and the gear ratios - planetary gear are primarily realated to the peripheral speed of the gears passing through the fluid.  Churning losses are difficult to calculate and estimates based on experience are often used in initial gear design.   The frictional losses are related to the gear design,the reduction ratio,the pressure angle, gear size, and the coefficient of friction.

Speed increaser gearbox

speed increaser gearbox generally may be used as speed increasers within the operating range for which they were designed as a reducer. Operating a gear reducer at higher speeds as a speed increaser will lead to significantly reduced load capacity and life, even at significantly reduced loads. Catastrophic failure due to thermal runaway is possible since lubricant churning losses and seal losses are speed dependent and not reduced with load. The gear reducer has a limited ability to dissipate these increased thermal loads.

miniature bevel gearbox in some applications

miniature bevel gearbox can be achieved in some applications. An everyday example, which illustrates the benefits of variable speed control, is the motorcar. lt has become such an integral part of our lives that we seldom think about the technology that it represents or that it is simply a variable speed platform. lt is used here to illustrate how bevel gear box are used to improve the speed, torque and energy performance of a machine. It is intuitively obvious that the speed of a motorcar must continuously be controlled by the driver (the operator) to match the trafiic conditions on the road (the process).

In a city, it is necessary to obey speed limits, avoid collisions and to start, accelerate, decelerate and stop when required.

On the open road, the main objective is to get to a destination safely in the shortest time without exceeding the speed limit.

Variable speed drives

The regenerative braking function is of great importance to the mechanical variable speed drives, which can effectively improve the efficiency of the system and realize the energy-saving purpose. Through the analysis and discussion of various regenerative circuits of variable speed drives, this paper provides a reference for practical application selection. The regenerative circuit based on the energy storage device and the common dc bus is suitable for certain applications. Based on the regeneration of the power electronic converter circuit, the current use very much, which USES the regeneration of the thyristor circuit, low cost, easy to achieve high power level, but because of thyristor is half controlled device, must consider the problem of the commutation of the need to take measures to ensure the reliable commutation, they inject a certain amount of harmonic current to the grid at the same time; Regeneration circuit type based on full controlled devices, although the cost is relatively high, but performance is good, can easily realize two-way flow of energy, and can significantly improve the power quality of grid side, therefore has good application prospect. Three - level dual PWM converter is also an optimal scheme for the application of regenerative circuits in multi-level topologies.

Identification of dynamic oil gearbox

1. Smell of oil: there is a burning smell of genuine oil;
2. Look at the liquidity of oil: after "hanging bottle" of genuine oil, it is not clear for a long time;
3. Oil bubble: after the oil is shaken, it is very rare.
4. Look at the viscosity of oil: it is not easy to get rid of genuine oil, and can pull wire.
If do not have the above characteristic, suggest you still be careful some, change the fake and inferior oil, the damage to transmission case is very serious, gain not worth to lose.

Mechanical variable speed drives

The speed of a mechanical variable speed drives controls the machine, pump, blower, agitator, and conveyer connected to it. Under normal circumstances, the motor running at a fixed speed, and manufacturing method of the motor speed depends on the power supply frequency, mechanical variable speed drives before was about to drive motor effectively change the power frequency, let the motor run at different speeds. The drives you can change any motor driven machines and equipment running speed, speed changes to the actual needs from the nature, can be finished by automatic or manual operation, so that the equipment running speed to meet the changing conditions.
