many types of Wuma gear speed reducer

Applications for Double-Enveloping Worm Gear Speed Reducers ,gear speed reducer offer high ratio reduction in a single stage, these drives provide a compact, low profile that is ideal for many types of mining equipment like feeder breakers, shuttles, and conveyors.The gear reductions offer a distinct advantage over cylindrical worm geometry. The increased number of teeth in contact greatly improves load sharing which translates into greater torque capacities for a given gearset.

Wuma transmission gearbox is made of close-grained cast iron

•Wuma transmission gearbox ：One-piece gearcase, without external ribs, speed reducers is made of close-grained cast iron and provides for rigid gear and bearing support.
It also offers excellent heat dissipation.
• Double lip, spring-loaded seals guard against oil leakage and prevent dirt from entering.
• Stepped shafts with oversized ball and tapered roller bearings.
• Carbon steel shafts for greater strength.
• High tensile strength cast bronze worm wheel and hardened and ground alloy steel worm made intregal with the shaft for long and trouble-free life.

high efficiency of Wuma planetary gearbox

Wuma planetary gearbox designed for servo applications requiring precision, durability, and long trouble free operation. The reducer motor are high efficiency gearheads that maximize the power transmission capability. They are designed with low backlash to reduce shock loads in dynamic reversing applications. They mount directly to the BSM servo motor family to provide torque multiplication, speed reduction, and inertia matching.

High quality precision combination gearbox for servo applications offering the following benefits: High input speeds Low moment of inertia High torsional rigidity Reduced backlash option High efficiency Can be mounted in any attitude Maintenance-free (applies to most applications).

the actual frequency of the mechanical variable speed gearbox

mechanical variable speed gearbox of the IGBTs in a PWM drive can range from 2 KHz to 15 KHz. Today's newer PWM designs use power IGBTs, which operate at these higher frequencies. By having more pulses in every half cycle, the motor whine associated with gearbox transmission is reduced because the motor windings are now oscillating at a frequency beyond the spectrum of human hearing. how each transition of the alternating voltage output is actually a series of short pulses of varying widths. By varying the width of the pulses in each half cycle, the average power produced has a sine-like output. The number of transitions from positive to negative per second determines the actual frequency to the motor.
