Abstract
A kind of structure of rotary forging machine head, main shaft is mainly arranged in the main bearing hole of housing by self-aligning bearing and thrust bearing by it, self-aligning bearing can bear unbalance loading well, axial force is born primarily of thrust bearing, the utility model has the feature of reasonable stress science, can extend the life-span of bearing significantly.
Description
Technical field
The utility model relates to a kind of metal forming machinery, is specifically related to rotary forging machine, particularly relates to the structure of rotary forging machine head, belongs to rotary forging machine technical field.
Background technology
As everyone knows, the head of rotary forging machine is the important process parts of rotary forging machine, in the course of the work, installation mold on it, rotary motion that is that head does in-plane under the driving of power or direction in space, compaction technology processing is done to the workpiece of heating, in production practices, the phenomenon that the bearing in roller face in front is usually damaged, cause roller fault rate higher, cause this to roll head inner bearing easily to damage, the higher main cause of fault rate except the higher reason of the environment temperature of its work and except, also be important reason with the unreasonable structure of existing rotary forging machine head.
The existing primary structure rolling head be by between power transmission shaft and housing by structure that a plain thrust bearing and a cylinder roller bearing are installed together, also have plenty of the structure installment form with taper roll bearing between power transmission shaft and housing, in this structure, thrust bearing and cylinder roller bearing are used for bearing axial force and radial load, or axial force and radial load are born by taper roll bearing, but, can be known by the working condition of pendulum mill, the power acted on power transmission shaft often has larger unbalance loading, thus, the stressed of bearing is also be in larger unbalance loading state, thus, in addition the effect of workpiece heat transmitted of mould, bearing easily damages, fault rate is higher.
Summary of the invention
The purpose of this utility model is exactly for the above-mentioned defect existing for existing pendulum mill, provides a kind of structure of rotary forging machine head of improvement.
The structure of the rotary forging machine head of described a kind of improvement, it is by power transmission shaft, sealing ring, self-aligning bearing first, spacer first, thrust bearing, self-aligning bearing second, spacer second, self-aligning bearing third, pressing plate, bolt, housing formed, described power transmission shaft forms by different three sections, that is: flange section, enlarged diameter section and reduced diameter section, described two ends, housing left and right are shaped with countershaft bearing bore and main bearing hole respectively, the enlarged diameter section of power transmission shaft is separately installed with thrust bearing and self-aligning bearing first, described thrust bearing and self-aligning bearing first outer ring are arranged in the main bearing hole of housing, thrust bearing is in the inner end in main bearing hole, thrust bearing and and self-aligning bearing first between enlarged diameter section on be provided with spacer first, the cylindrical of flange section connects with the port part of main bearing hole, the outside diameter of flange section is slightly less than the internal diameter of main bearing hole, the cylindrical of flange section and main bearing hole port part are provided with sealing ring, the cylindrical of reduced diameter section is provided with self-aligning bearing second and self-aligning bearing third, self-aligning bearing second connects with the cylindrical of countershaft bearing bore with the outer ring of self-aligning bearing third, the cylindrical of the reduced diameter section between self-aligning bearing second and self-aligning bearing third is provided with spacer second, there is bolt to fix a pressing plate in the end of reduced diameter section.
Beneficial effect: as can be seen from the structure chart of the utility model point, when the end bearing partial load of power transmission shaft, self-aligning bearing first adapts to the partial load produced automatically, and bear radial load, and axial force is born by thrust bearing, so, there is the feature of reasonable stress science, so the utility model can extend the life-span of bearing significantly.
