Abstract
Nozzle ring capable of changing cross sections is carried out to a heat filter structure for pretension, comprise belleville spring heat filter and split ring back-up ring.Described belleville spring heat filter is provided with boss.The dome of bearing support one end is provided with the annular slot for construction opening check ring.Belleville spring heat filter is arranged on the dome of bearing support one end, and split ring back-up ring is arranged in annular slot, prevents belleville spring heat filter from the dome of bearing support, play and swing occurring.After installing, belleville spring heat filter is pressed on the end surface of step hole of nozzle ring capable of changing cross sections blade seat, and utilizes the blade seat of spring force by nozzle ring capable of changing cross sections of belleville spring heat filter, spacer sleeve and bonnet to be pressed on turbine box.
Description
Technical field
The utility model relates to turbocharger of motor technical field, and particularly a kind of heat filter that utilizes carries out the structure of pretension to nozzle ring capable of changing cross sections.
Background technique
At present, variable-geometry cross section turbosupercharger is widely used on motor, and this pressurized machine is by external control driving mechanism, changes turbine circulation gullet section and amasss, reach and control the effect that engine exhaust flows into turbine, improve low operating mode pressure ratio and acceleration performance with this.
Existing turbosupercharger heat filter 1 structure is as shown in accompanying drawing 1,2, its behaviour in service as shown in Figure 3, heat filter 1 is arranged on impeller shaft 4, and the Main Function of heat filter 1 is used to stop that the heat in turbine box 2 is delivered to bearing support 3, ensures the lubrication effect of bearing support 3.
There is following problem in existing turbosupercharger heat filter 1: one to be that heat filter 1 is only used to heat insulation, can not be used for carrying out pretension to nozzle ring capable of changing cross sections; Two is that heat filter 1 is arranged on impeller shaft 4, unfixing, there is play and dancing, brings hidden danger to the work of turbosupercharger.
Summary of the invention
The purpose of this utility model be overcome prior art above-mentioned deficiency and provide a kind of heat filter that utilizes to carry out the structure of pretension to nozzle ring capable of changing cross sections.
The technical solution of the utility model is: a kind of heat filter structure of nozzle ring capable of changing cross sections being carried out to pretension, comprises belleville spring heat filter and split ring back-up ring.
Described belleville spring heat filter is provided with boss.
The dome of bearing support one end is provided with the annular slot for construction opening check ring.
Belleville spring heat filter is arranged on the dome of bearing support one end, and split ring back-up ring is arranged in annular slot, prevents belleville spring heat filter from the dome of bearing support, play and swing occurring.After installing, belleville spring heat filter is pressed on the end surface of step hole of nozzle ring capable of changing cross sections blade seat, and utilizes the blade seat of spring force by nozzle ring capable of changing cross sections of belleville spring heat filter, spacer sleeve and bonnet to be pressed on turbine box.
The utility model compared with prior art has following features:
What 1, the utility model provided utilizes the pretightening force of belleville spring heat filter to be pressed on turbine box by blade seat, spacer sleeve, bonnet to the heat filter structure that nozzle ring capable of changing cross sections carries out pretension, decrease the friction caused because of blade rotation, greatly improve the reliability of nozzle blade work.
2, belleville spring heat filter is arranged on the dome of bearing support one end, split ring back-up ring is arranged in annular slot, utilize split ring back-up ring to prevent belleville spring heat filter from the dome of bearing support, play and swing occurring, eliminate heat filter generation play and swing the work hidden danger brought.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
