Abstract
The utility model provides a frock is adjusted to sealing ring, its characterized in that, adjust the frock and include adjusting disk and location axle, the adjusting disk includes the locating hole, the location axle runs through locating hole and sealing ring, the adjusting disk with the cooperation of location axle is used for fixing the sealing ring. The utility model discloses, the damage that the sealing ring of having solved turbo cooler arouses because of leading to scraping with the impeller axiality deviation is great can reduce the installation degree of difficulty of sealing ring, improves the assembly reliability.
Description
Technical Field
The utility model belongs to aviation environmental control system turbine cooler's assembly field, concretely relates to frock is adjusted to sealing ring.
Background
The seal ring is a key component of the turbine cooler, and the radial clearance between the seal ring and the impeller directly influences the service life and the reliability of the turbine cooler. The turbine cooler is a high-speed rotatory mechanical structure, and for guaranteeing the product leakproofness, the clearance of sealing ring and impeller is less, and sealing ring and turbine wheel are in the installation, owing to lack the positioning means of sealing ring, and the sealing ring often can be scraped with the impeller, and when the turbine cooler started, because of the higher part damage that causes of rotational speed. In the installation process of the sealing ring and the impeller, the radial positioning of the sealing ring is an important means for ensuring the installation reliability of the sealing ring and the impeller.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a sealing ring axiality adjustment disk, in the installation of sealing ring and impeller, at first carry out radial regulation to the sealing ring, avoid sealing ring and impeller to scratch and cause the part to damage.
The technical scheme of the utility model: the utility model provides a frock is adjusted to sealing ring, its characterized in that, adjust the frock and include adjusting disk and location axle 5, the adjusting disk includes locating hole 2, location axle 5 runs through locating hole 2 and sealing ring 6, the adjusting disk with location axle 5 cooperation is used for fixing sealing ring 6.
Further, the adjusting disc is a conical body.
Furthermore, a counter bore is arranged on one end face of the adjusting disc, and the counter bore is coaxial with the positioning hole 2.
Further, the diameter of the section of one side, close to the counter bore, of the adjusting disc is smaller than the diameter of the section of one side, far away from the counter bore, of the adjusting disc.
Further, the adjusting disc and the positioning shaft 5 are made of stainless steel materials.
Further, the conditioning disk surface contains a nitrided or carburized layer.
The invention has the beneficial effects that: the sealing ring coaxiality adjusting disc can improve the coaxiality of the sealing ring and the impeller and improve the installation reliability of the turbine cooler.

FIG. 3 is a second schematic view illustrating the use of the seal ring adjusting tool according to the present embodiment;
description of reference numerals: 1-adjusting disk, 2-locating hole, 3-conical surface, 4-impeller, 5-shaft, 6 are sealing rings.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, and reference is made to fig. 1-3 of the specification.
This embodiment provides a frock is adjusted to sealing ring, adjust the frock and include adjusting disk 1 and location axle 5, adjusting disk 1 includes locating hole 2, location axle 5 runs through locating hole 2 and sealing ring 6, the adjusting disk with the cooperation of location axle 5 is used for fixing sealing ring 6.
In particular, the adjusting disk 1 is a conical body. A counter bore is arranged on one end face of the adjusting disc 1 and is coaxial with the positioning hole 2. The section diameter of one side, close to the counter bore, of the adjusting disc 1 is smaller than the section diameter of one side, far away from the counter bore, of the adjusting disc. The adjusting disc and the positioning shaft 5 are made of stainless steel materials. The surface of the regulating disk 1 comprises a nitriding or carburizing layer.
FIG. 2 is a first schematic view illustrating the use of the seal ring adjusting tool of the present embodiment; fig. 3 is a second schematic view illustrating the use of the seal ring adjusting tool according to the present embodiment. Combine fig. 2 and fig. 3, when the installation turbine cooler, locating hole 2 of adjusting disk wears on axle 5, adjusts the radial position of sealing ring 6 through conical surface 3, installs impeller 4 again to guarantee the axiality of sealing ring 6 and impeller 4, avoid because of the less scratch and the damage that arouses in clearance. The surface of the conditioning disk of this embodiment contains a nitrided or carburized layer, which can improve the surface strength of the conditioning disk.
