Tractor gearbox for PTO drive shaft, agricultural machines 540 rpm, 3:1 ratio, China manufacturer OEM / ODM
- ISO 500-1 General specifications, safety requirements, dimensions for master shield and clearance zone
- ISO 500-2 Narrow-track tractors, dimensions for master shield and clearance zone
- ISO 500-3 Main PTO dimensions and spline dimensions, location of PTO.
The original type calls for operation at 540 revolutions per minute (RPM). A shaft that rotates at 540 rpm has 6 splines on it, and a diameter of 1⅜”. Two newer types, supporting higher power applications, operate at 1000 RPM and differ in shaft size. The larger shaft has 20 splines (1¾” diameter), while the smaller has 21 (1⅜” diameter). All three types rotate counterclockwise when viewed from the tractor (When standing behind the tractor, the shaft turns clockwise). A 10 spline type was used with some early equipment such as the 1948 Land Rover, a six spline adapter was usually supplied. It is customary for agricultural machines manufacturers to provide the nominal PTO power specification, an indication of the available instantaneous power at the shaft.
The PTO rotational speed was specified as 536 ± 10 rpm; the direction was clockwise. The speed was later changed to 540 rpm.
Truck transmissions have one or more locations which allow for a PTO to be mounted. The PTO must be purchased separately and care is required to match the physical interface of the transmission with a compatible PTO. PTO suppliers will usually require details of the make, model and even serial number of the transmission. Care is also needed to ensure that the physical space around the transmission allows for installation of the PTO. The PTO is engaged/disengaged using the main transmission clutch and a remote control mechanism which operates on the PTO itself. Typically an air valve is used to engage the PTO, but a mechanical linkage, electric or hydraulic mechanism are also options.
Most Unimogs come with front and/or rear PTO’s and hydraulics as well as three point hitch systems.
Units will be rated according to the continuous and intermittent torque that can be applied through them and different models will offer different “PTO shaft rotation to engine RPM” ratios.
In the majority of cases, the PTO will connect directly to a hydraulic pump. This allows for transmission of mechanical force through the hydraulic fluid system to any location around the vehicle where a hydraulic motor will convert it back into rotary or linear mechanical force. Typical applications include:
- Running a water pump on a fire engine or water truck
- Running a truck mounted hot water extraction machine for carpet cleaning (driving vacuum blower and high-pressure solution pumps)
- Powering a blower system used to move dry materials such as cement
- Raising a dump truck bed
- Operating the mechanical arm on a bucket truck used by electrical maintenance personnel or Cable TV maintenance crews
- Operating a winch on a tow truck
- Operating the compactor on a garbage truck
- Operating a Boom/Grapple truck
- Operating a truck mounted tree spade and lift-mast assembly
