NL type nylon coupling, TGL type nylon inner gear ring gear
coupling product display, first of all give a brief overview of
this product.
NL type nylon coupling, TGL type nylon inner gear ring gear
coupling are the latest domestic products and have been widely used
abroad. The transmission half coupling adopts precision casting,
cast iron HT20-40, cast iron Steel ZG35Ⅱ, No. 45 steel, shaft hole
and keyway are drawn and formed, nylon inner gear coupling
elastomer jacket can be selected from various hardness synthetic
nylon, reinforced casting nylon elastomer and other materials
according to user requirements.
NL type nylon inner gear coupling structure:
Changsheng NL type nylon internal gear coupling is produced in
accordance with GB3852-83 "Coupling Shaft Hole and Keyway Form and
Size". It is composed of flanged half-coupling with external teeth
and nylon gear ring with the same number of teeth. The flanged
half-coupling with external teeth is placed in the nylon gear ring
with internal teeth, and the driving end teeth face the nylon gear.
The axial force of the ring gear drives the driven end to transmit
motion and power.
Features of NL type nylon internal gear coupling:
1. It is suitable for inter-shaft and flexible transmission,
allowing large axial, radial and angular displacement, and has the
advantages of simple structure, convenience, easy disassembly, low
noise, small loss of transmission efficiency, and long service
life.
2. Nylon internal gear couplings do not require high machining
accuracy, and can be used for various horizontal and vertical
transmission shafts of medium and small power, mainly suitable for
various gear pumps, thermal oil pumps, heavy oil pumps, sewage
pumps, centrifugal pumps and Gear oil pump, etc.
