Abstract
The utility model discloses a swinging-vane turbine with alterable nozzle consisted of a turbine casing, an impeller, rotatable nozzle ring vanes and a governing mechanism. It utilizes the governing mechanism changing the angle of the nozzle ring vanes to alter turbine circulating section. The utility model is applied to match the turbine supercharger with the engine and realize continuous no back play adjustment of the turbine circulating section.
Description
Technical field
The utility model is a kind of blade-rotation variable nozzle turbine, is mainly used in the motor on automobile, special vehicle, engineering machinery, the boats and ships, belongs to technical field of engines.
Background technique
Turbo-charged diesel is the major impetus of China's military vehicle, civilian vehicle, engineering machinery and boats and ships.Along with the raising of supercharging pressure ratio, adopt conventional pressurized machine that diesel engine starting, acceleration performance are worsened, low speed torque deficiency, over-emitting black exhaust etc. do not meet the technical performance requirement of modern power plant.The variable nozzle turbine regulation technology is the effective measures that solve above-mentioned supercharged diesel engine matching problem, can make motor when low speed, keep higher boost pressure, simultaneously boost pressure is unlikely excessive during high speed, realizes pressurized machine and the matched well of motor in the whole working condition scope.
In the blade-rotation variable section turbocharger patent that has been applied (982520662 and 992576342), the rotation of nozzle blade also is to rely on initiatively shift fork drive drive plate, and then drive that driven shift fork rotates, but initiatively shift fork, driven shift fork are to be connected with drive plate by the shifting block on the drive plate, there is bigger gap between them, when work, bigger idle running can occur, influence the precision of nozzle blade position regulation.In addition, the operating temperature of turbine variable cross section controlling mechanism is very high, and drive plate at high temperature can produce distortion, the relative position between drive plate and the shift fork is changed, the idle running when further increasing work.Owing to have idle running between the moving parts of controlling mechanism, make the degree of regulation variation of turbine nozzle ring leaf position, the matching performance of turbosupercharger and motor is affected.
Summary of the invention
In order to overcome the deficiency of existing adjustable turbine, the utility model provides a kind of novel blade-rotation variable nozzle turbine, and this turbine can overcome the idle running between the controlling mechanism moving parts, realizes the continuous adjusting of turbine flow area.
The technical solution used in the present invention is: variable nozzle turbine is made up of turbine case, impeller, rotating nozzle blade and controlling mechanism, controlling mechanism is arranged on the end of pressurized machine intermediate 1 by turbine, comprises blade installation dish, drive plate, active shift fork, driven shift fork, transmission shaft and driveshaft; One of driven shift fork links to each other with the rotating shaft axle of nozzle blade, and the other end is connected in the gear engagement mode with drive plate, and initiatively one of shift fork is connected in the gear engagement mode with drive plate, and the other end links to each other with transmission shaft.The utility model is to regulate the turbine flow area by rotary nozzle ring blade, when regulating, driveshaft drives transmission shaft and rotates, the active shift fork that is connected in transmission shaft is rotated, thereby stirring drive plate rotates, rotate thereby drive the driven shift fork that is connected in drive plate, the nozzle blade that is connected in driven shift fork rotates thereupon.
The present invention overcomes that the technical measures of idle running have 2 points between the movement parts: 1) drive plate is to adopt the gear engagement mode with being connected between shift fork and the passive shift fork initiatively, when drive plate is rotated with active shift fork and passive shift fork between movement clearance reduce greatly; 2) drive plate adopts opening mode, relies on the relative position between elasticity maintenance and the shift fork when temperature variation, the idle running that has occurred when having reduced temperature variation.
Beneficial effect of the present invention is: can overcome the idle running that exists between the existing variable nozzle turbine controlling mechanism movement parts effectively, accurately regulate the turbine nozzle ring cross section, realize the matched well of variable-area turbocharger and motor.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Variable nozzle turbine is made up of turbine case 7, impeller 8, rotating nozzle blade 6 and controlling mechanism, controlling mechanism is arranged on the end of pressurized machine intermediate 1 by turbine, comprises blade installation dish 4, drive plate 3, active shift fork 9, driven shift fork 2, transmission shaft 10 and driveshaft 11; The hole that blade installation dish 4 is inserted in the rotating shaft 5 of nozzle blade 6, the other end of rotating shaft 5 links to each other with the driven shift fork 2 that drives nozzle blade 6 rotations; The other end of driven shift fork 2 is connected in the gear engagement mode with drive plate 3, on the drive plate 3 with the number of the engaging groove of driven shift fork 2 and blade installation dish 4 on the number in hole equate that it is right that driven shift fork 2 and nozzle blade 6 are combined; Initiatively 9 one of shift forks also are connected in the gear engagement mode with drive plate 3, and the other end links to each other with transmission shaft 10.
When carrying out the adjusting of nozzle ring flow area, the course of action of entire mechanism is as follows: driveshaft 11 drives transmission shaft 10 and rotates, the active shift fork 9 that is connected in transmission shaft is rotated, thereby stirring drive plate 3 rotates, rotate thereby drive the driven shift fork 2 that is connected in drive plate 3, the rotating shaft 5 that is connected in driven shift fork 2 drives nozzle blade 6 and rotates.Because initiatively the Placement between shift fork 9, driven shift fork 2 and the drive plate 3 is a gear engagement, and drive plate 3 has a port 12, has elasticity, the idle running that produces in the time of can eliminating the controlling mechanism motion.
