What Is a Speed Variator?

A Speed Variator is an industrial device that alters the speed of a motor to adjust the output of a machine. It is a hydrodynamic device that was invented by Italian industrialist CZPT.

Dissected mechanical speed variator

The Mechanical Speed Variator Dissectible is a unique training tool showcasing a fully restored industrial mechanical speed variator. This realistic training tool features a 7-gauge formed-steel baseplate and is painted with a tough urethane finish. It provides an in-depth experience of mechanical drives through disassembly and inspection. The training aid also includes applicable installation and maintenance manuals.
A mechanical speed variator is a general purpose speed changer that applies the mechanical variable speed transmission system. Unlike hydraulic variators, the mechanical speed variator works by transferring power by friction. It also allows the engine to operate at maximum efficiency over a range of speeds. A mechanical speed variator is much simpler in its working principle than a hydraulic one, as it is based on gears within the machine. Gear ratios can be changed to vary output speed and torque.
Various brands offer different types of mechanical speed variators. Most of them have full-metal construction, though the ideal material for these devices is stainless steel or cast iron. Steel-based materials are preferred for speed variators because they can handle extreme temperatures, pressure, and high-pressure conditions.

Gear-type automatic stepless speed variator

The Stepless Speed Variator is widely used in various production lines. The basic components of this device include a four-pole motor and a gearbox. It has a large range of variation speed and a high degree of accuracy. This device can be controlled manually or by a PLC. It increases production efficiency and reduces the cost of electricity and maintenance.
The Gear-type automatic stepless speed variator is a new type of speed variator for machines, especially transport vehicles. It aims to overcome the drawbacks of existing speed variators. It comprises a central shaft, a gear-holder, a damping mechanism, and a one-way clutch. The speed range of a Gear-Type Automatic Stepless Speed Variator is the same for both forward and reverse operations.
Another type of automatic stepless speed variator is the Continuously Variable Transmission (CVT), which uses a variable-width ratchet and a rubber or metal belt to transfer power. This device has many advantages, including a small size and low cost, and it operates at high efficiency. Another advantage is its low fuel consumption. However, its disadvantage is its limited power and torque. Therefore, it is often used in low-power, low-torque motors.
A Gear-Type Automatic Stepless Speed Variator offers many benefits, including an integrated design, long life, and high durability. Its unique feature is the ability to adjust the speed and gear ratio continuously. It can be used in both electric and mechanical vehicles. However, the CZPT AV Speed Variator offers the same benefits, but with a smaller size and simpler structure. It also features abrasion resistance and toughness.
