The gearbox is an essential component of machines used in a number of industries and applications. Gearboxes are designed to increase output torque or change the speed of a motor (RPM). The motor shaft is connected to one end of the gearbox, and the gear ratio controls how much torque and speed the gear arrangement produces. Different designs and specifications of gearboxes are utilized in agricultural, industrial, construction, mining, and automotive equipment, and they are available in a variety of configurations. This article will look at the many types of transmissions and their key properties.
Various Forms Of Industrial Gearboxes
The six most popular types of industrial gearboxes are described below.
Helical Gearbox
The helical gearbox is compact and energy-efficient. This equipment is used for a wide range of industrial applications, however it is most commonly used for heavy-duty jobs. Helical gearboxes are widely used in the plastics, cement, and rubber industries, as well as other heavy industrial applications. This material could be useful in low-power applications including crushers, extruders, coolers, and conveyors.
The helical gearbox is unique in that it is positioned at an angle, allowing several teeth to interact in the same direction while in motion. This ensures that communication continues for a set period of time.

Coaxial Helical Inline Gearbox
The coaxial helical gearbox is best suited for heavy-duty applications. Coaxial helical inlet lines are noted for their high quality and efficacy. These are manufactured to high specifications, allowing you to optimize load and transmission ratios.
Bevel Helical Gearbox
This type of gearbox is identified by a number of curved teeth located on a cone-shaped surface at the unit's rim. The bevel helical gearbox generates rotational motion between shafts that are not parallel. Common applications include quarries, the mining industry, and conveyors.
Skew Bevel Helical Gearbox
The skew bevel helical gearbox's sturdy and monolithic structure makes it ideal for usage with heavy loads and other applications. When installed on the suitable motor shaft output, these industrial gearboxes give mechanical benefits. They are highly adjustable in terms of tooth count and gear ratio. As a result, you're likely to find one that matches your needs.
Worm Reduction Gearboxes
Worm reduction gearboxes power heavy-duty operations. These gearboxes are employed when a higher speed reduction is required between crossing axis shafts that do not meet. This type of industrial gearbox uses a large-diameter worm wheel. The worm or screw engages the teeth on the gearbox's outer area. The wheel moves in a screw-like pattern as a result of the worm's rotation. The vast majority of these gearboxes are employed in heavy industries such as fertilizer, chemicals, and minerals.
Planetary Gearbox
Three or four Planet Gears surround the Sun Gear in the center of a Planetary Gearbox. All of them are connected by a ring gear with internal teeth. This design enables a Planetary Gear System to provide great torque in a small space by uniformly dispersing power throughout the gears. This Gearbox type is widely used in cutting-edge technologies such as robots and 3D printing.
The planetary gearbox is ideal for precision applications due to its longevity, accuracy, and particular functionality. This type of gearbox improves the reliability and performance of your equipment. Planetary gearboxes are available in both solid and hollow configurations, with a variety of mounting options including a flange, shaft, or foot.

Various Types Of Automobile Gearbox
Various kinds of automotive transmissions are detailed here.
Manual Transmission
A manual gearbox requires the driver to manually select all ratios using a moveable gear selector and a clutch that is operated by the driver. This transmission type is sometimes referred to as a "stick shift" or a "conventional" transmission.
Sliding-Gear Transmission
Sliding-gear gearboxes were only used in older autos. When the gearbox is in neutral, the primary drive and cluster gears are in motion within the transmission case. Pushing the clutch pedal moves the shifter handle, which transmits power to the drive wheels (front or rear). Moving the shifter handle changes the position of the shift linkage and forks, as well as the location of a gear immediately above the cluster gear on the main shaft.
Constant-Mesh Transmission
Continuous-mesh transmissions, often known as synchronized transmissions, keep the driving, cluster, and main shaft gears in constant motion. Because the gears are free to rotate around the main shaft, this is possible. A dog clutch is used to lock these gears in place as needed. When the shift linkage is changed, the dog clutches and main shaft gear teeth interlock, keeping the gear in place. Synchronizers in constant-mesh gearboxes prevent clashing or grinding during shifts.
Pre-selector Transmission
Manual transmissions, like everything else, evolved and changed over time as automakers experimented with design. Wilson Pre-selector was a type of manual transmission developed before automated transmissions became common.
Automatic Transmission
While practically all manual transmissions follow the same principles, automatic transmissions are distinct entities. Regardless of the mechanics of an automatic transmission, the driver will recognize Park, Reverse, Neutral, and Drive, possibly with additional settings such as Sport and manual shifting mode. A gear lever on an automated transmission is just an electrical switch that sends an instruction to the software that regulates the gearbox. As a result, designers have started to manage the gearbox via buttons, paddles, or dials instead of traditional levers.
Torque Converter
The most common type of automatic gearbox uses a torque converter to deliver the engine's rotational force to the wheels. A torque converter is a fluid connection that allows the vehicle to accelerate and decelerate without stalling the engine, but with reduced efficiency due to the curved shape of the turbine blades within the converter. This type of gearbox is advantageous because it accelerates smoothly from low speeds and is responsive at low engine rpm.
Automated-Manual Transmission
An automated-manual gearbox is a type of automatic transmission that employs a standard clutch and gear arrangement while simulating manual gear operation with sensors, actuators, processors, and pneumatics. These vehicles are infamous for their jerky engine performance at low speeds and difficult acceleration, yet they provide good fuel economy over long distances.
Dual-Clutch Transmissions (DCT)
This transmission is gradually becoming the most popular type of automatic transmission for gas and diesel automobiles. The majority of Volkswagen Group brands, including VW, SEAT, and Skoda, refer to it as a DSG (direct shift gearbox); however, Audi adds to the confusion by calling it an S-Tronic, and Porsche prefers the acronym PDK.
This type of gearbox delivers the same direct experience as a single-clutch transmission, but it is frequently more efficient and easier to use. In most circumstances, it may offer better fuel efficiency and performance than a manual transmission. There may still be some jerkiness at low speeds, and switching between first and reverse may be awkward.

Continuously Variable Transmission (CVT)
A CVT has no gears. Instead, it adopts a cone shape with a band and a secondary axle. The band can be moved up and down the cone to modify its length and, hence, the gear ratio. In theory, it may change the ratios between its upper and lower limits forever, allowing it to be optimally set for fuel economy or performance at any time. This is especially helpful for hybrid automobiles, which may use a CVT to balance the workload of the gasoline engine and electric motor.
