Swelling connected sets of installation, removal and protection

1, Installation: expansion set at the factory coated with a lubricant, can be directly installed. When installed the first part ① the holes in the flange bolts screwed into renault megane car gps dvd ④ uniform along the circumference, the inner sleeve ①, ② to open the top coat. Then the expansion sets the location of the hub bore into the design, the use of force plates hand-tighten the bolts, tighten each bolt method is a time to the rated torque of screw 1 / 4, tighten the order to open joints for the sector, followed by about crossing symmetry has tightened to ensure rated torque.
2, removal: remove all the grp/frp storage tank to relax when the first few laps. Then remove the screw holes in the ground within the cross-bolts screwed into the top loose ④ expansion sets.
3, protection: the installation to prevent the expansion sets pollution, prohibited the use of MoS2 oil. Operating or working in the open on the machine the less, should be regularly exposed bolts on the expansion sleeve end and coated anti-rust oil, rust should be used in the expansion of a better set of patterns.
swelling coupling sleeve is a modern new advanced machine parts. Is widely used to implement parts of today's RoHs driver for led screen and shaft coupling, by tightening the screws to 12.9 inclusive high-intensity surface and the friction between the pressure generated by the load transfer to achieve a new keyless coupling device.
this interference with the normal link, a key link than the expansion set of links has many unique advantages:
1, using the expansion set to host parts manufacturing and installation simple. Install the shaft and hole expansion sets like interference with the processing requirements of high precision manufacturing tolerances as. Expansion units are not required to install heating, cooling or pressure equipment, only to bolt torque required to tighten. And easy adjustment wheel on the shaft can be easily adjusted to the desired location. Expansion kits can also be used to link poor welding parts.
2, expansion sets of long life, high strength. Expansion kits rely on friction drive, coupling pieces being weakened without keyway, no relative motion, no work wear.
3, inflation sets in overload, it will lose the coupling effect, can protect equipment from damage.
4, can withstand multiple expansion units connected load, the structure can be made into a variety of styles. Depending on the installation size of the load, multiple expansion units can also be used in tandem.
5, expansion sets to led light power supply the demolition, and has a good interchangeability. As the expansion sleeve with a large gap can combine the hub, remove the bolt will loosen the coupling can be easy to open. Swelling when in close contact with the surface rust is not easy to fit, but also easy to open.
expansion sets are widely used in textile, packaging, machine tools, metallurgy and other industries of lady's handbag and equipment.
