The novel electric heating furnace has the advantages of long service life, reliable work, simple production process, low price cost and high production efficiency.
Description
Technical Field
The utility model relates to a slide bearing especially relates to a locomotive is spherical gasket for differential.
Background
In the traditional SF-1 spherical gasket, a layer of PTFE (polytetrafluoroethylene) material is arranged on the inner spherical surface of a friction pair of the spherical gasket, the surface has no oil holes, and the wear-resistant layer of PTFE is thin, so that the wear-resistant layer can be lubricated without oil in a general sense, but the wear-resistant layer is not ideal for use under the working conditions of high speed and heavy load, namely the service life of the wear-resistant layer is short for the use occasions with large PV values (the product of load and movement speed). The differential is a very critical and complex part for realizing driving and steering of the locomotive, and the safety factor requirement in design is higher, so that the design of a safe and reliable spherical gasket with long service life is very necessary.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a reliable operation, friction factor are little, bearing capacity is strong, long service life's a locomotive is spherical gasket for differential.
In order to meet the requirement, the utility model discloses a locomotive is spherical gasket for differential, its characterized in that it is the sphere gasket of making with bronze alloy material, and the center system of gasket has the round hole, is covered with the pit that has sphere or prism on the indent surface of sphere gasket, as the oil pocket of storing lubricating oil.
The bronze alloy material is CuSn6.5P0.1 or CuSn8P0.3.
The lower surface of the bronze alloy material is also compounded with a steel plate.
The area of the oil holes accounts for 20-40% of the surface area.
According to the spherical gasket for the locomotive differential designed by the scheme, the manufactured spherical gasket is made of the bronze alloy material or the composite material of the bronze alloy and the steel plate, so that the bearing capacity of the spherical gasket is greatly improved, and meanwhile, spherical or prismatic oil holes are formed in the surface of the friction pair of the spherical gasket, so that a wedge-shaped leading-in angle which is convenient for lubricating oil to be led into the friction pair is formed no matter the spherical gasket for the locomotive differential rotates clockwise or anticlockwise or swings relative to the spherical surface at the friction end, the lubricating oil can smoothly enter the friction pair to form an oil film, the lubricating condition and the heat dissipation performance of the friction pair are improved, and the abrasion and the gluing of parts are reduced. During the forming and processing of the arc-shaped surface oil groove, the spherical gasket can be manufactured by pressing a hard spherical or prismatic pressure head on a corresponding plane plate and then performing cold stamping forming. The novel electric heating furnace has the advantages of long service life, reliable work, simple production process, low price cost and high production efficiency.
