The disassembly method of the coupling and the precautions for maintenance

　　1. When disassembling, mark the position between the pulley or coupling and the rotating shaft first, screw the factory fixing screws and pins, and then slowly pull it out with a puller.If you can't pull it out, you can pour some kerosene into the inner hole and pull it out.If it still can't be pulled out, use rapid fire around the pulley or coupling to quickly heat it. At the same time, wrap the shaft with a damp cloth and continuously pour cold water to prevent heat from being introduced into the motor.

　　2. When assembling.First use a fine iron emery cloth to smooth the shaft hole of the shaft, pulley or coupling, align the pulley or coupling with the keyway and put it on the shaft, pad one end of the key with wrought iron or hardwood, and gently tap the key. Into the slot.

　　The key should be properly tight in the groove. Too tight or too loose will damage the key and groove, and too loose will cause the belt to slip or vibrate.Drum gear coupling is a new type of gear coupling developed on the basis of spur gear coupling, digesting and absorbing foreign advanced technology.It is composed of an outer gear sleeve with a drum-shaped tooth thickness and a matching inner gear ring that connects two shafts. It is suitable for heavy load and two-axis transmission that requires axis displacement compensation.Under normal circumstances, it is required that the two shafts to be connected are concentric, and it is impossible to continue to maintain the concentric state during operation. Because of installation errors, bearing wear, force deformation, foundation sinking, etc., the axis produces radial and angular directions. To displacement.

　　The drum gear coupling has the characteristics of compensating the above displacement, reduces the additional load caused by the axis displacement, improves the working stability and reliability of the transmission device, and thus prolongs the service life of the transmission device.The diaphragm coupling is composed of at least one diaphragm and two shaft sleeves.The diaphragm is fastened to the shaft sleeve with a pin and generally does not loosen or cause backlash between the diaphragm and the shaft sleeve.Some manufacturers provide two diaphragms, and some provide three diaphragms, with one or two rigid elements in the middle, and the coupling is connected to the shaft sleeve on both sides.

　　Matters needing attention in coupling maintenance

　　(1) The basic requirements for its inspection: the connection must be stable, the connecting bolts and connecting keys must not be loosened, and the radial and end surface jumps in the transmission should not be obvious when viewed visually. , When using the instrument to check, it cannot be greater than.

　　(2) Gear-type safety inspection: It needs to be removed for inspection when the transmission noise increases or the product is overhauled.

　　(3) Elastic inspection: When the rubber ring and the leather pad are damaged, they need to be replaced as soon as possible. If the pin or hole is destroyed and vibration occurs, it is necessary to drill an angle of rotation of the half body once. Hole, replace the standard new pin, you can not expand the original hole with a new pin.

　　(4) There are problems such as whether the sealing of the lubricating series oil is intact, the oil is deteriorated, and the oil leaks out.When the above situation occurs, the seal and oil need to be replaced. When the oil is lacking, it needs to be replenished as soon as possible.
