Abstract
The invention discloses metal forming machinery equipment, in particular to a forcing press combination bearing used on a crank and a connecting bar of a forcing press. The combination bearing is assembled by a rolling bearing, a sliding bearing, a gland, a spacer bush and related fastening pieces. As the sliding bearing bears no force when the forcing press is in idle running and idle motion states, friction work of the sliding bearing is greatly reduced. When the forcing press is in stamping process, the rolling bearing and the sliding bearing bear load together, and the load bearing capacity of the sliding bearing can be brought into full play, thereby adapting to the high-speed rotation of the force press. The combination bearing has the advantages of high reliability, a long service life, low manufacturing cost, compact structure and convenience to be popularized and used.
Description
Technical field
The present invention relates to a kind of forging equipment, be specifically related to be installed in the combination bearing between press crankshaft, the connecting rod.
Background technique
At present, sliding bearing is adopted in high speed pressure machine crankshaft and connecting rod joint more, also claims axle sleeve, bearing shell.In order to guarantee the bent axle favorable rigidity, the affluence amount in the design is generally big than ordinary press, so just makes the bent axle diameter dimension more many greatly than the size of ordinary press.If still adopt sliding bearing, must strengthen the surface friction drag that produces in the process of running up, the insufficient lubrication of sliding bearing, press machine is when running up, the bearing load that frequently withstands shocks, the anti-fatigue ability of material and seizure resistance, compliance, embedding are hidden sexual needs and are further improved, and have increased manufacture cost greatly, and working life is low.Sliding bearing has higher coaxality requirement to the bent axle support zone on the technology, if coaxality is poor, can cause the overheating in the machine tool running process equally, the bearing excessive wear occurs so that phenomenons such as " burning to death ".
Summary of the invention
The objective of the invention is to overcome the above-mentioned shortcoming of prior art, a kind of press compound bearing is provided.It is that two rolling bearings are installed at the connecting rod two ends, the middle sliding bearing of installing.
The present invention realizes with following technological scheme: a kind of press compound bearing comprises press crankshaft, connecting rod and is installed in bearing between the crankshaft-and-connecting-rod surface of contact that it is characterized in that: described bearing is a combination bearing.
Described combination bearing comprises rolling bearing, sliding bearing, bearing gland, spacer and attachment screw, packing ring; Two rolling bearings are installed between the counterbore at described connecting rod two ends and the external cylindrical surface of bent axle, and two bearing glands are connected with the end face of connecting rod by screw, packing ring; Described spacer is sleeved on the root of bent axle, and described tubular shape sliding bearing drive fit is sleeved in the hole at connecting rod middle part, and both ends of the surface are near the interior ring end face of rolling bearing; Keep certain clearance between the endoporus of described sliding bearing and the external cylindrical surface of bent axle.
Good effect of the present invention is:
1, can satisfy running up of speed change press machine, reach more than the 500spm.
2, because sliding bearing does not stress long service life, good reliability when press machine air transport, commentaries on classics idle stroke.
3, the combination bearing low cost of manufacture is easy to utilize.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is a structural drawing of the present invention.
Among the figure: 1, bent axle, 2, connecting rod, 3, bearing gland, 4, rolling bearing, 5, sliding bearing, 6, spacer, 7, screw, packing ring.
As shown in drawings, a kind of press compound bearing, comprise press crankshaft 1, connecting rod 2 and be installed in bent axle 1 and connecting rod 2 surface of contact between bearing, it is characterized in that: described bearing is a combination bearing.
Described combination bearing comprises rolling bearing 4, sliding bearing 5, bearing gland 3, spacer 6 and attachment screw, packing ring 7; 4, two bearing glands of two rolling bearings 3 are installed between the counterbore at described connecting rod 2 two ends and the external cylindrical surface of bent axle 1 to be connected with the end face of connecting rod 2 by screw, packing ring 7; Described spacer 6 is sleeved on the root of bent axle 1, and described tubular shape sliding bearing 5 drive fits are sleeved in the hole at connecting rod 2 middle parts, and both ends of the surface are near the interior ring end face of rolling bearing 4; Keep certain clearance between the external cylindrical surface of the endoporus of described sliding bearing 5 and bent axle 1.
As shown in drawings, when lathe no load running and idle stroke, sliding bearing 5 contacts hardly with bent axle 1, has reduced the frictional work of sliding bearing 5, improves the working life and the reliability of sliding bearing 5 greatly.In stamping process, rolling bearing 4 load that at first is hit, little resiliently deformable takes place after, with sliding bearing 5 bearing loads, can give full play to the bearing capacity of sliding bearing 5.Can adapt to running up of press machine, facts have proved that running speed is more than 500spm.The reliability and the life-span of machine tool running are greatly improved.Reduce the manufacture cost of sliding bearing simultaneously.Compact structure of the present invention is convenient to promote the use of.
