Abstract
A changeable nozzle ring positioning structure is improved from an existing changeable nozzle blade through the method that sunk screw installation holes on an existing changeable nozzle blade seat is changed into three pin holes, three sunk screws and three spacer sleeves are removed and a disc-shaped rear cover is added. A circular groove used for installing a positioning check ring is arranged on the excircle of the disc-shaped rear cover, the positioning check ring is placed inside the circular groove, and the three pin holes are arranged on the end face of the disc-shaped rear cover. A blade seat and the disc-shaped rear cover are connected into a whole through three step pins, and the three threaded holes provided with the changeable nozzle inside an existing turbine box are removed. A circular cavity is arranged on the end face provided with the changeable nozzle inside the turbine box, and the circular groove used for installing the positioning check ring is placed on the inner wall of the circular cavity. During the process of installing, the disc-shaped rear cover on the changeable nozzle is installed inside the circular cavity of the turbine box, and at the same time, the positioning check ring installed on the disc-shaped rear cover is clamped into the circular groove of the circular cavity of the turbine box, and the changeable nozzle is installed inside the turbine box through the positioning check ring.
Description
Technical field
The utility model 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 that satisfies low fuel consume, low emission and high power density of vehicular engine.Constantly strict along with Abgasgesetz will reach state's III, state's IV and more maximum discharge standard, and adopting variable nozzle turbocharging is a kind of effective technical measures.
To be adjustable vane rotate around separately axle center the principle of variable-nozzle technology jointly, change along with blade angle, angle and speed that the minimum actual internal area of turbo machine and exhaust enter turbine all will change, thereby 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 and form, blade seat 6 is provided with three sunk screw mounting hole 6-1, three sunk screw mounting hole 6-1 are evenly distributed on the end face of blade seat 6.The end face of turbine box 9 interior installation variable-nozzles is provided with three tapped hole 9-1, and three tapped hole 9-1 are evenly distributed on the end face that variable-nozzle is installed.Variable-nozzle is installed on the turbine box 9 by three sunk screws 8, three spacer sleeves 7 that are enclosed within respectively on the screw 8.
Above structure has the following disadvantages: the one, and it is more that part is installed quantity, and efficient is low; The 2nd, this kind mounting type has determined that the setting angle of turbine box and bearing support must be unique, if the setting angle of pressurized machine whirlpool end changes, needs new design turbine box, and versatility is poor.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of variable nozzle ring position structure is provided.
The technical solution of the utility model is, a kind of variable nozzle ring position structure, it is to change the sunk screw mounting hole 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.The cylindrical of disc bonnet is provided with to install the circular groove of positioning retainer ring, positioning retainer ring is installed on the disc bonnet cylindrical in the circular groove, end face at the 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 the disc bonnet, one end of step pin and the pin hole on the blade seat adopt interference fit, pin hole on the other end of step pin and the disc bonnet adopts interference fit, by three step pins blade seat and disc bonnet is connected to one.Three tapped holes of variable-nozzle are installed in the existing turbine box of cancellation, and the end face that variable-nozzle is installed in turbine box arranges a toroidal cavity, at the inwall of toroidal cavity a circular groove that is used for installing positioning retainer ring is set.
During installation, the disc bonnet on the variable-nozzle is installed in the toroidal cavity of turbine box, is installed in the circular groove in the toroidal cavity that positioning retainer ring on the disc bonnet snaps in turbine box simultaneously, by positioning retainer ring variable-nozzle is installed in the turbine box.After installing, the edge of the relative blade seat of turbine box circumferentially can be freely movable, so just can select suitable setting angle according to the motor installation requirements.
The utility model compared with prior art has following features:
The one, whole assembling is simple, and easy to operate, efficient is high; The 2nd, part universality is strong, is fit to various setting angle needs on the various motors, the suitable popularization.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
