1. Subject Content and Scope of Application
JB/T6005-92
This standard specifies the type, model and series parameters of the inner and outer rotors of medium and small power internal combustion engine oil pumps. This standard applies to powder metallurgy inner and outer rotors (hereinafter referred to as inner and outer rotors) of medium and small power internal combustion engine oil pumps. Non-powder metallurgy inner and outer rotors can also refer to this standard.

3.1 Gear ratio i
The ratio of the number of teeth Z of the inner rotor to the number of teeth Z of the outer rotor, i.e. Z/Z3.2 Eccentricity e
The distance between the center of the inner rotor and the center of the outer rotor when the inner and outer rotors are in meshing condition, mm. 3.3 Clearance 8
The radial distance between the top of the inner rotor tooth and the root of the outer rotor tooth when the inner and outer rotors are in meshing condition, mm. 4 Type, model and series parameters
4.1 Type
The rotor profile is a trochoid.
4.2 Model
The series model name is composed of the Latin letters JBZ, the outer diameter of the outer rotor and the rotor width. JBZ=××-××Www.bzxZ.net
Rotor width, mm
Outer diameter of outer rotor, mm
