Description

Known machines for lapping parts, c. which one of the latter is stationary, and the other gets one-handedly with reciprocating axial displacements or alternating rotation in either direction, whether it is constant to one side. In this machine, for the purpose of simultaneously fitting the valve and piston, the appropriate gears were used to communicate the above movements to the rubbed parts.

In FIG. I depicts a side view of the machine; FIG. 2 is a plan view.

The proposed machine is set in motion by motor J and, in the part intended for grinding valves, consists of shaft 3 with gear gear 3 transmitting rotation to shaft 7 through gear 6. Conical gear 8 on shaft 7 rotates gears 9 and 10 za to shaft 44, of which gear 10 transmits rotation to shaft 12 through gear 11, Krivoschip 16 at the end of shaft 44 is connected to pgatun 17, -directed by stops 15 and informing rotation in both directions of washer 8-19, fixed by screw 20 on shaft 14. Euchlnaya 13 on shaft 18 informs the spring-pressed valve 21 axis th is moved, the wood clips 23 hold cylinder 82 in a fixed position. Another part of the machine, designed for grinding piston rings, consists of a shaft 5, gears 8 4

and crankshaft 5, crank 45, crosshead 85 in sled 86 and cone 58, mounted and rotated in recess 8 of crosshead 85. Fist 89 connects cone to stem 50, having a square cross-section corresponding to the cross section of the hole in gear 32 fenced from axial displacement stops 31, but communicating the rod .50 rotational movement, it receives from the shaft 5 through the bevel gears 33, 34, 35, 86 and 57.

A piston or brush 48 for cleaning the cylinder, mounted on the piston 39, covered with a rigid casing 40, upholstered in leather 41, is placed in the cylinder 58, swaged in wooden parts 43.

The machine is set in motion by motor 1, at which the valve 21 receives a movement in both directions from the rod 17 and at the same time a periodic translational movement from the fists 13 and the spring-pressing valve springs at the same time, the rod 50 receives rotation from gear 36-31 -accessible movement from the crank 45.

The subject of the patent.

A machine for lapping valves and piston rings, in which the valve and piston simultaneously with axial reciprocating movements receive rotation: the first alternating in both directions,

the second is one-sided using appropriate gears, characterized by cumulative use of: a) a mechanism for communicating the required movements to the valve consisting of a washer 19 mounted on its spindle 14 19 alternately rotated in both directions by a connecting rod I coupled to a crank 16 at the end of the shaft 44, rotated by means of a corresponding transmission by motor 1 and driving shaft 12 with fist rotation

a washer 13 telling the spring-pressed valve to axial movement b) of the mechanism for communicating the required displacements to the piston consists of the rod 50 receiving the reciprocating axial movements also from the motor 1 by means of the corresponding gear and shaft 5, by means of the crank mechanism 84, 45 transmitting rotation using a gear transmission to the above ztoku 30.
