Abstract
The utility model discloses a valve rocker shaft seat, which mainly comprises a seat body, rocker shafts, rocker shaft grooves and shaft seat mounting bolt holes. The rocker shafts are arranged on the front surface and the back surface of the seat body and integrally designed with the seat body, wherein the rocker shaft at one side is used as a rocker shaft of an inlet valve, the rocker arm shaft on the other side is used as a rocker shaft of an exhaust valve, and the rocker shaft of the inlet valve and the rocker shaft of the exhaust valve are arranged on the same central line. The rocker shaft grooves are arranged on the rocker shafts, wherein one rocker shaft groove is close to the end surface of the seat body, and the rocker shaft grooves are mainly matched with an oil filling hole in a rocker rotating shaft hole, thereby realizing an oil storage function during rotation. The two shaft seat mounting bolt holes are vertically arranged at two ends of the seat body and used for mounting the whole shaft seat.
Description
(1) technical field
The utility model relates to engine art, is specifically related to the valve rocker axle bed in a kind of motor inlet and outlet door controlling device.
(2) background technique
The engine valve regulating system is one of important device in the engine control parts, in the distribution device of motor, the effect of pneumatic door control system is according to the job order of motor and working procedure, time opening and close intake valve or exhaust valve, make inflammable mixture or air enter cylinder, and waste gas is discharged.The distribution device of motor generally is made up of timing gear, peach oblique crank Z, valve actuating push rod, pitman arm shaft (seat), rocking arm, intake valve, intake valve return spring and valve tappet etc.Rocker shaft bed is the core component of carrying inlet valve rocker and exhaust valve rocker arm, general rocker shaft bed is on structural design; pitman arm shaft relies on bearing means to be installed on the rocker shaft bed; perhaps by with moving back the designs fix of the formula of pulling out in rocker shaft bed; though this kind method manufacture process is simple relatively; owing to related to the assembly precision of a plurality of links, therefore to whole rocker arrangement precision in the running keep with lubricated maintenance on certain influence is arranged.
(3) summary of the invention
The utility model mainly provides a kind of novel valve rocker axle bed, and main technical schemes is as follows:
A kind of valve rocker axle bed mainly comprises pedestal, pitman arm shaft, pitman arm shaft groove, axle bed construction bolt hole.Described pitman arm shaft is arranged on positive and negative two of pedestal, and with pedestal be the design of integral type, wherein a side pitman arm shaft is as the inlet valve rocker axle, and the opposite side pitman arm shaft can be used as the exhaust valve rocker arm axle, and inlet valve rocker axle and exhaust valve rocker arm axle are arranged on the same center line.Pitman arm shaft is provided with the pitman arm shaft groove, the end face of one of them pitman arm shaft groove next-door neighbour pedestal, and pitman arm shaft groove oil hole main and in the rocker shaft hole matches, and the function of store oil is arranged when rotating.Two ends of described pedestal vertically are provided with two axle bed construction bolt holes, are mainly used in the installation of whole axle bed.
Valve rocker axle bed described in the utility model adopts and to water foundry goods and make through the integrated type processing mode, and pitman arm shaft and axle bed are the integral type setting, and the installation of having save split-type design and precision adjustment etc. go on foot and gather.The groove that designs on the pitman arm shaft mainly is to match with the rotary shaft hole of rocker member, can make in the greasing substance storage and groove unnecessary when turning round.Valve rocker axle bed described in the utility model does not have the employing bearing connection, and is easy to maintenance, as long as guarantee that during fabrication the smoothness of corresponding contact face and pitman arm shaft periphery requires.
