Description
Technical field
The present invention relates to turbo-charger technical field, particularly a kind of variable nozzle ring position structure of turbosupercharger.
Background technique
Turbocharging technology is the important means meeting the low fuel consume of vehicular engine, low emission and high power density.Constantly strict along with Abgasgesetz, reach state III, state IV and more maximum discharge standard, adopt variable nozzle turbocharging to be a kind of effective technical measures.
The principle of variable-nozzle technology is that adjustable vane rotates jointly around respective axle center, along with the change of blade angle, the minimum actual internal area of turbo machine and exhaust enter the angle of turbine and speed all will change, thus change the rotating speed of turbo machine and the boost pressure of blower outlet end.
Existing variable-nozzle is by driving ring 1, supporting wheel
2, support wheel shaft 3, driven Rocker arm 4, blade 5, blade seat 6, spacer sleeve 7, sunk screw 8 form, blade seat 6 is provided with three sunk screw mounting hole 6-1, and three sunk screw mounting hole 6-1 are evenly distributed on the end face of blade seat 6.The end face installing variable-nozzle in turbine box 9 is provided with three tapped hole 9-1, and three tapped hole 9-1 are evenly distributed on the end face of installation variable-nozzle.Variable-nozzle is arranged on turbine box 9 by three sunk screws, 8, three spacer sleeves 7 be enclosed within respectively on screw 8.
Above structure has the following disadvantages: one is that part installation quantity is more, and efficiency is low; Two to be that this kind of mounting type determines the setting angle of turbine box and bearing support necessarily unique, if the setting angle of pressurized machine whirlpool end changes, needs newly to design turbine box, poor universality.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art and a kind of variable nozzle ring position structure is provided.
Technological scheme of the present invention is, a kind of variable nozzle ring position structure, it changes the sunk screw mounting hole of three on the blade seat of existing variable-nozzle into three pin holes, cancels three sunk screws and three spacer sleeves, then increases a disc bonnet.Disc bonnet cylindrical is radially provided with the circular groove for installing positioning retainer ring, positioning retainer ring to be arranged on disc bonnet cylindrical in circular groove, the end face of disc bonnet is provided with three pin holes, and three pin holes are evenly distributed on the end face of disc bonnet.Blade seat is connected by three step pins with disc bonnet, pin hole on one end of step pin and blade seat adopts interference fit, pin hole on the other end of step pin and disc bonnet adopts interference fit, blade seat and disc bonnet is connected to one by three step pins.Cancel three tapped holes installing variable-nozzle in existing turbine box, the end face installing variable-nozzle arranges a toroidal cavity, the inwall of toroidal cavity arranges the circular groove that is used for installing positioning retainer ring in turbine box.
During installation, the disc bonnet on variable-nozzle is arranged in the toroidal cavity of turbine box, and the positioning retainer ring be arranged on disc bonnet snaps in the circular groove in the toroidal cavity of turbine box simultaneously, is arranged in turbine box by variable-nozzle by positioning retainer ring.After installing, turbine box relative vane seat circumferentially can be freely movable, so just can select suitable setting angle according to motor installation requirements.
The present invention compared with prior art has following features:
One is that overall assembling is simple, and easy to operate, efficiency is high; Two is that part universality is strong, is applicable to various setting angle needs on various motor, suitable popularization.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present invention is further described.
