Description
Source data:
Linkage:
Diameter of cylinders d, m. 0,12
The ratio of the piston stroke to its diameter N / d, 1.45
Length ratio 0.23
Crankshaft speed 1 n1, rpm. 1900
Moment of inertia of the blower Jvozd, kg·m2 0.25
Maximum pressure in the cylinders pmax , MPa 6.4
The coefficient of unevenness of rotation of the crank 1 0.01
The position of the crank 1 in the power calculation of the mechanism φ1, deg. 120
When calculating, take:
1. Weight of links: connecting rods 2 – , where q = 15 kg/m; l is the length of the connecting rod in m;
pistons 3 and 5 – ; crank 1 – ;
2. Moments of inertia: connecting rods; crank
3. The center of mass of the connecting rods is at point S, AS = 0.33AB
4. Camber angle of cylinders α = 90°
Gearing:
The number of teeth of the wheels of simple transmission = 26:9
Planetary gear ratio UH-1 1 /3
The gear module of the planetary mechanism m = 4 mm.
Simple gear wheel module ( ) m = 8 mm.
Cam gear:
Pusher stroke h, mm, 12
Phase angles of rotation of the cam, = 0
Pusher weight mT, kg. 0,3
Pusher acceleration ratio 1.6
Permissible pressure angle in the cam mechanism
The law of change in the analogue of the acceleration of the pusher in the phases of removal and return is the same.
