Abstract
The utility model discloses a toothed bimetallic self-lubricating bearing, which relates to the field of sliding contact bearings and is composed of cylindrical metal rings formed by rolling bimetallic self-lubricating plates, wherein the opening parts are butted in a sawtooth mode, so that the opening parts of the rolled metal rings can be mutually matched. The zigzag shape is preferably triangular or square. The bearing structure has the beneficial effects that the size of the bearing structure is more stable because the connection stress of the sawtooth structure is small and the opening is easy to form by interaction.
Description
Technical Field
The utility model relates to the field of bimetal composite self-lubricating bearings, in particular to a tooth-jointed bimetal self-lubricating bearing.
Background
The bimetal self-lubricating bearing is made up by sintering graphite-containing copper alloy layer on the surface of metal base body and rolling, and features high binding strength, low cost, high bearing capacity and high temp. However, such self-lubricating bearing openings are typically in the form of straight-sided abutments. The structural form has the defect that the bimetal material has strong stress, so that the forming at the opening is not good, and the inner diameter size precision and the oil film formation after the assembly are greatly influenced. Resulting in uneven friction and wear during use and seriously reducing the service life of the bearing.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a tooth-jointed bimetal self-lubricating bearing which ensures convenient assembly, stable size, low cost and uniform friction surface, and solves the problems in the background technology.
In order to achieve the above purpose, the method comprises the following steps:
the toothed bimetallic self-lubricating bearing consists of cylindrical metal rings, and the openings of the cylindrical metal rings are butted in a sawtooth mode, so that the openings of the metal rings after being rolled are convenient to be mutually matched.
Preferably, the cylindrical metal ring is formed by rolling a rolled rectangular bimetallic plate.
In a further refinement, the saw tooth form may be a triangular or square saw tooth, as well as other saw tooth forms that facilitate milling machining.
The utility model has the beneficial effects that: because the stress at the connection part between the teeth is relatively small due to the sawtooth structure, the opening of the bearing is easy to form by interaction, and the bearing structure is more stable in size due to the design under the condition that the specification of the bearing is determined.

fig. 2 is a front view of a metal ring of the bearing.
Detailed Description
The utility model will be further explained and illustrated with reference to the following examples and the accompanying drawings.
Example (b): referring to fig. 1 and fig. 2, the present invention provides a technical solution: the toothed bimetallic self-lubricating bearing is composed of a cylindrical metal ring formed by rolling a bimetallic self-lubricating plate, and the opening parts are butted in a sawtooth form. The saw tooth form is preferably triangular or square saw teeth.
The raw material for manufacturing the self-lubricating bearing is a rolled rectangular bimetallic plate, has self-lubricating property, and is specifically made of graphite and copper alloy.
The processing method comprises the following steps: processing a rectangular plate according to the specification and size, and manufacturing a sawtooth structure of an opening part; and then a rolling machine is adopted for rolling and forming, and finally the goodness of fit of the opening part is checked, so that no obvious size change is caused at the bearing opening part.
