Agricultural Lawn Mower Gearbox 140

Gear Ratios of  lawn mower gearbox?

A gear ratio is simply how many revolutions a driven gear will turn in relation to the main drive gear. In a low gear ratio of 3:1, for example, the driven gear will turn three times as much as the main gear providing increased torque but since it’s spinning three times as fast, the engine’s speed (RPM) will quickly max out.
Oppositely a 1:3 gear ratio will turn at a third of revolutions of the input gear, thus providing less torque, but increasing the ability of the engine to spin slower to maintain a higher rate of speed.

Lawn Mower Gearbox 140 Transmission Types

There are four basic types of transmissions:

1. Manual Transmissions are found on sports cars and older lawn tractors. The gears are manually selected using a lever and clutch. Users report a responsive, more immediate feeling of power.
2. Hydrostatic Transmissions (also known as automatic transmissions) use hydraulic fluid to shift gears automatically. These are the most common type of transmission on the market. They are relatively easy to maintain and provide a good mix of responsiveness and ease of use.
3. Friction-Disc Transmissions are mainly used on small power equipment. They have a spinning disc with a movable wheel on top. Just like a record player, as the wheel moves across the disc from the center, it creates varying degrees of speed and torque. They’re inexpensive but require more maintenance. Users sometimes report lurching and jerky-ness while operating the shifters.
4. CVT Transmissions, or continuously-variable transmissions, are becoming more common. They employ a metal band sandwiched between two cone-shaped pullies that alter their diameters and thus their gear ratios. Users often report a ‘rubber-band’ effect after revving the engine, in which the power sent to the wheels feels delayed. The chief benefit is that the transmission is always in the ‘best’ gear ratio for the given power demand.

We Also Supply PTO Shafts

A PTO shaft is an extremely sophisticated mechanism that allows implements to draw energy from an engine. It works with a mechanical agricultural gearbox. A PTO shaft can be mounted on a vehicle’s transmission, and is an essential part of the system. A high-quality PTO shaft should be durable enough to withstand torsion and minimize vibration. Power-trans manufactures a wide range of durable PTO shafts to meet all your requirements.

Customized service of agricultural gearbox

Our agricultural gearbox has many items for your choice and we can produce as per your drawing or sample to meet your special request

1. Large output torque
2. Safe, reliable, economical, and durable
3. Stable transmission, quiet operation
4. High carrying ability
5. High modularization design, may equip with various outer power inputs conveniently. The same machine type may equip with various power motors. It is easy to realize the combination and junction between every machine type
6. Transmission ratio: Fine division, wide scope. The combined machine type may form a very large transmission ratio, i. E. Output very low rotary speed.
7. Form of installation: The position to be installed is not limited.
8. High strength, compact the box body of high strength cast iron, gear and gear shaft adopt the gas carbonization, quenching, and fine grinding process, therefore the bearing capacity of unit volume is high.
9. Long life: Under the condition of the correct type chosen(including choosing suitable operation parament ) normal operation and maintenance, the life of the main parts speed reducer(except wearing parts)should not be less than 20000 hours. The wearing parts include lubricating oil, oil seal, and bearing.
10. Low noise: Because the main parts of the speed reducer are processed, and tested critically, therefore the noise of the speed reducer is low.
11. Our gearbox has reached the advanced international level and can replace the same kind of products imported.
