Shaft Coupling GHC Series Aluminium Flexible 40x50mm Oldham Style Coupling
Products Introduction
These are Oldham couplings. We are the manufactures of producing all kinds of shaft coupling. Customized couplings are also acceptable.
The Oldham type shaft coupling are designed to clamp evenly around the shaft and provide greater retention than fixed screw couplings without damaging shaft. Then tighten the clamping screws to secure.
Its shape is light and convenient to install, which saves time for the processing and production of enterprises. Secondly, it is resistant to oil corrosion and can be electrically insulated. Different slider elastomers are available.
The sliding between the shaft sleeve and the intermediate piece can allow large radial and angular deviations. The special bump design in the middle can play a supporting role and allow large angular deviations without bending moment, so as to minimize the axial load
Advantages of the Oldham coupling:
First of all, its shape is light and easy to install, which saves time for the processing and production of enterprises. Secondly, it is resistant to oil corrosion and can be electrically insulated. Different slider elastomers are available. The sliding between the bushing and the middle piece can tolerate large radial and angular deviations. The angle deviation does not generate bending moment, so that the axial load is minimized.
Secondly, the structure is simple, the size range is wide, the moment of inertia is small, the use is convenient, and it is convenient for visual inspection. Superior oil corrosion resistance and electrical insulation minimize the axial load caused by misalignment, and the sliding between the bushing and the middle can tolerate large radial and angular misalignments.
Compared with other couplings, first of all, its shape looks particularly light, and this kind of thing is the most eye-catching, and the cross slider in the middle has different colors for you to choose from, and it is also easy to install. It is not troublesome. The biggest thing is that it can save maintenance and at the same time, it can also be insulated from electricity, anti-fouling and anti-corrosion, and its service life is relatively long. It is a very economical and suitable coupling
