Abstract
A marine diesel engine aligning roller bearing comprises an outer ring, an inner ring, a first line of spherical rolling elements, a second line of spherical rolling elements, a retainer for the firstline of spherical rolling elements, a retainer for the second line of spherical rolling elements and a middle spacer. The outer ring is a single spherical raceway and is composed of a first half ringand a second half ring. A first curved surface raceway and a second curved surface raceway with the same curvature radius are arranged on the outer wall of the inner ring so as to form a double curvature raceway. Two axial positioning holes at an angle of 90 degrees are arranged on the inner ring. A first sealed bench and a second sealed bench are respectively arranged on two sides of the outer wall of the inner ring. The marine diesel engine aligning roller bearing has the outer ring which is a double half outer ring structure which enables a high rotating speed; and the inner ring has two axial positioning holes at an angle of 90 degrees, which can improve the bearing rotating speed and the reliability; the sealed benches are arranged on two sides of the inner ring to cause the equipment to be compact; and the steel plate stamping retainers control the roller string momentum through contracting the tyre and increase the rotating speed.
Description
Technical field
The utility model relates to a kind of selfaligning roller bearing, a kind of specifically marine diesel engine double-row self-aligning roller bearing that is applicable to high rotating speed, highi degree of accuracy assembling, compact device and installation and convenient disassembly.
Background technique
Existing marine diesel engine selfaligning roller bearing adopts the double-row self-aligning roller bearing of routine or standard usually.Its outer ring is the one spherical raceway, can not adjust bearing clearance after the installation, is difficult to adjust the bearing axial position, and its airframe bearing speed capability is low, easily produces unbalance loading, poor reliability, and equipment part is more, and it is bigger to take up room, the manufacture cost height, inconvenience is installed.
Summary of the invention
The purpose of this utility model is low in order to overcome the speed capability that exists in the prior art, easily produces unbalance loading, poor reliability, equipment part is more, and it is bigger to take up room, the manufacture cost height, defectives such as inconvenience installation, and provide a kind of marine diesel oil machine bearing speed capability height that can make, reliability height, compact structure, the highi degree of accuracy assembling, the marine diesel engine selfaligning roller bearing of installation and convenient disassembly.
The technological scheme that adopts is:
The marine diesel engine selfaligning roller bearing comprises outer ring, inner ring, two row spherial rolling bodies.Two row spherial rolling bodies are installed in respectively by in the pocket hole on rammed two retainers of two body steel plates of middle spacer ring guiding, and are installed in the raceway that forms between inner ring and the outer ring.Its technological points is: the outer ring is single spherical raceway, and inner ring is two iso-curvature raceways.The outer end of two row spherial rolling bodies contact with the single spherical raceway coupling of outer ring respectively, and the inner of two row spherial rolling bodies is mated with the corresponding raceway of two iso-curvature raceways of inner ring respectively and contacted.
Described outer ring is single spherical raceway double semi outer rings structure.
Described inner ring is be separated by 90 ° axially locating hole of two of interior astragals.
Described inner ring is an inner ring both sides band sealing platform.
Described retainer is the two body steel plate pressing cages by middle spacer ring guiding of control roller string quantity of motion.
The utility model adopts as above technological scheme, and its beneficial effect is as follows:
The marine diesel engine selfaligning roller bearing of the utility model design, two row spherial rolling bodies, the retainer that is coated in the curved surface raceway and on described raceway, turns round by the maintenance two row spherial rolling bodies of middle spacer ring guiding.Compare with the double-row self-aligning roller bearing of common employing routine or standard: 1, the outer ring is the double semi outer rings structure, realizes installing axially play adjustment of back in equipment trial run process, reaches high speed capability.2, the adjustment of rear bearing axial position can be realized installing in two of interior astragals, 90 ° the axially locating hole that is separated by, and prevents unbalance loading, improves bearing speed capability and reliability.3, inner ring both sides band sealing platform forms sealing with gland, makes compact equipment.4, the steel plate pressing cage improves speed capability by shrinking tire control roller string quantity of motion.
