Abstract
The invention discloses an anti-vibration flexible structure for connection of a booster foot and a diesel booster mount. The booster foot is connected with the diesel booster mount through a bolt. The anti-vibration flexible structure is characterized in that an elastic washer is arranged between the bolt and the booster foot, and the diameter of an unthreaded hole in the bolt of the booster foot is 1.4-2.8 times greater than the outer diameter of the bolt. The anti-vibration flexible structure has the advantages that the anti-vibration structure for the connection of the booster foot and the diesel booster mount can be arranged in the small place, the inflexible connecting structure of the booster foot and the diesel booster mount is changed into a flexible one, and anti-vibration capability of the whole structure is improved.
Description
Technical field
The invention belongs to turbomachinery technical field, relate to a kind of vibrationproof flexible structure be connected with diesel pressure booster base for pressurized machine lower margin.
Background technique
Reduction oil consumption and emissions reduction are the main targets of diesel engine study and development always.Various for meeting that these require and in the measure taked, supercharging technology is one of the most effective means.Current almost all kinds of diesel engine all have employed exhaust turbine pressuring technology.But often because long-term diesel engine and pressurized machine dither separately causes the fracture of pressurized machine lower margin connecting bolt, even causes the appearance of the crackle of the pressurized machine mounting base of diesel engine in using.
Summary of the invention
The respective dither that the present invention be directed to due to diesel engine and pressurized machine causes the fracture of pressurized machine lower margin connecting bolt, even causes the problems such as the appearance of the pressurized machine mounting base crackle of diesel engine, proposes a kind of vibrationproof flexible structure connected for pressurized machine lower margin.This structure is simple and easy to use, easy accessibility.
This pressurized machine lower margin is connected with diesel pressure booster fitting seat uses vibrationproof flexible structure, pressurized machine lower margin and diesel pressure booster fitting seat are bolted, elastic washer is provided with between bolt and pressurized machine lower margin, in pressurized machine lower margin, the unthreaded hole diameter of bolt is bolt external diameter 1.4 to 2.8 times, make the linkage structure of pressurized machine lower margin and diesel pressure booster fitting seat become flexibility from rigid, add the vibration resistance of total.
In order to better realize goal of the invention of the present invention, described elastic washer is provided with nut vibration-proof section and bolt parcel, and nut vibration-proof section is arranged between the nut of bolt and pressurized machine lower margin, and bolt parcel is wrapped in around the bolt in pressurized machine lower margin.
For ensureing the intensity of elastic washer, should have angle of inclination outside the bolt parcel of elastic washer, with the unthreaded hole inwall angle C of bolt in pressurized machine lower margin outside described elastic washer bolt parcel, C is 0 ° to 90 °.
Compared with prior art, its beneficial effect is in the present invention: achieve and arrange the vibration-proof structure that pressurized machine lower margin is connected with diesel pressure booster fitting seat in less space.The linkage structure of pressurized machine lower margin and diesel pressure booster fitting seat has become flexibility from rigid, adds the vibration resistance of total.
Accompanying drawing explanation
Fig. 1 is the protective equipment schematic diagram of turbosupercharger axial flow turbine fracture.
Reference character is as follows: 1-bolt, 2-elastic washer, 3-pressurized machine lower margin, 4-diesel pressure booster fitting seat, with the unthreaded hole inwall angle of bolt in pressurized machine lower margin outside the bolt parcel of C-elastic washer, and 21-nut nut vibration-proof section, 22-bolt parcel.
