Product Description

JM II Type Diaphragm Coupling Without Sinking Hole

JM series diaphragm flexible coupling is widely used in machinery and equipment industry, metallurgy, mines, petroleum, chemical, electric power, shipbuilding, lifting transport, textile, light industry, agricultural machinery, printing machinery and water pump, fan, etc. in the transmission of power machine.

                 

The main characteristics of JM Series Diaphragm Coupling
1.Compensation 2 axis misalignment of the ability, and tooth type coupling can be much more than a double angle displacement, radial displacement of the small, flexible, allowing a certain axial, radial and angular displacement.
2. Obvious damping effect, no noise, no wear and tear.
3.High transmission efficiency, up to 99.86%. Especially suitable for medium and high speed high power transmission.
4.Adapt to high temperature (-80+300) and harsh environment, and can be in shock, vibration, safety and dynamic conditions.
5.Simple structure, light weight, small size, convenient assembly and disassembly. Without moving the machine can be disassembled (with intermediate type), no need of lubrication.
6.Accurately convey the rotational speed, the operation has not turned bad, can be used for the transmission of precision machinery.

Shaft Collar

PTO Shafts and PTO Shaft Shields

When choosing a PTO shaft, measuring the various pieces is an important aspect. Each piece must be measured in a specific way, with the shaft in a closed position. Measure the length between the outsides of the yokes. The closed length will help you determine the correct PTO series size for the horsepower of your tractor.

540 rpm

A 540 RPM PTO Shaft will fit CZPT PTO models. These shafts are slightly indexed to allow for easy PTO drive hookups. These shafts will also work with 1000 RPM implements. They also feature a snap ring that will allow for quick and easy removal.
PTO shafts are commonly divided into two types: 1000 RPM and 540 RPM. The 540 RPM PTO shafts are smaller, with only six splines, while the 1000 RPM PTO shafts are larger. The 540 RPM version is used with implements that require less horsepower and are made for light-duty use.
The PTO shaft transfers power from the tractor’s engine to a PTO-driven implement. When operating at its recommended speed, the PTO shaft rotates at 540 rpm (9 times per second). The higher speed PTO shafts have more splines.

Safety chains

Safety chains for PTO shafts are an important safety feature to consider when operating a tractor. These chains are welded to the drive end of a tractor or implement. They are used to prevent the plastic shield from spinning on the PTO shaft. The chain’s reaction time is slower than the speed of the PTO shaft, which makes it important for safety.
When operating a tractor, it is important to follow the manufacturer’s instructions and keep the machine and equipment in a safe location. A poorly-guarded PTO can entrap ground personnel or cause a serious accident. Operator awareness is also important. It is important to avoid stepping over a revolving shaft, wearing loose clothing, or making repairs while the tractor is running. It is also important to follow the manufacturer’s instructions and use the PTO for its intended purpose.
The safety chains for PTO shafts must be properly connected and fully functional before each use. During a PTO operation, the PTO shaft may rotate as much as 1000 rpm, which is potentially deadly. In addition to safety chains, the tractor should have a clutch or torque limiter fitted on the implement end.
The PTO shaft must have a correct length for the machine. If it is a sliding metal PTO drive shaft, it is important to lubricate it according to manufacturer’s specifications. Lubrication is recommended after every eight hours of operation. Also, make sure that the button on the end of the PTO shaft moves freely. Hammering it into place can damage the guard and the shaft.
A PTO driveline hazard is one of the oldest farm machinery hazards. It refers to the PTO or Implement Input Connection. There are often protruding pins and bolts on the driveline, which can snag clothing.

Shield

Shaft CollarThe PTO shaft shield is a protective piece that encloses a PTO shaft. These shields are usually plastic, but some are also made of metal. They are made to protect the PTO shaft from debris, which can cause premature wear and damage to the universal joints. A PTO shaft shield is not a permanent fixture, but can be easily removed for replacement or repair.
The PTO shaft shield should be checked periodically to ensure that it is in good condition. It should have no loose ends or loose bolts. Ensure that the shear bolts and pins are the right length and hardness for the PTO shaft. Additionally, the operator should wear snug clothing to avoid stepping on the PTO shaft while working.
The PTO shaft shield should fit snugly over the PTO shaft. If the PTO shaft is loose, it may be difficult to attach the safety shield. However, with a proper PTO shaft shield, the process should be quick and easy. A CZPT safety clip allows easy removal and prevents co-rotation between the inner driveshaft and the safety shield. The driveline safety shield from RPM Transmissions is made of CZPT, which is a rigid and durable material.
In addition, some machine drive shafts are lacking a shield. This can cause a safety hazard. Without a PTO shaft shield, an operator may accidentally touch the shaft and get injured. These guards prevent this danger by enclosing the shaft in a plastic or metal guard.
The PTO shaft shield is a crucial part of tractor safety. It helps protect the operator from accidental entanglement while operating the tractor. When the PTO shaft stub becomes separated, it can cause severe injuries and even fatalities. Thankfully, the industry has made tremendous progress in reducing the risks associated with PTO mishaps. Operators must make sure they maintain the shields and do not remove them if not in use.

Reverse rotation

Shaft CollarThe PTO shaft reverse rotation mechanism prevents the main drive shaft from moving in a direction opposite to the direction of rotation of the driven shaft. The mechanism is compact, reducing the length of the rotation shaft. The mechanism includes two reversing members: first reversing member 151 rotates in a clockwise direction and second reversing member 153 rotates in a counterclockwise direction.
In a PTO shaft reverse rotation mechanism, a driven shaft is inserted into a hollow cylindrical body. It is rotatably positioned relative to the main driving shaft 112 and radially symmetrically around it. As a result, the driving and reverse-rotation mechanisms are symmetric.
One such PTO shaft reverse rotation mechanism has a main drive shaft and a driven shaft, and a plurality of transmission units coupled to it. The driven shaft and the transmission member rotate in tandem. The transmission units are arranged radially about the main driving member and the driven shaft. Alternatively, one of the reversing units may comprise the second reversing member and the first driving member.
