Abstract
The utility model provides a crankshaft and a bearing shell, which is composed of a crankshaft, a bearing shell seat, a thrust bearing of a bearing shell cover, a positioning bolt, and a lock bolt. The utility model is characterized in that the end of the crankshaft is provided with a cone-shaped shaft, the inner circle of the bearing shell is a cone-shaped hole, the bearing shell is tallied with the cone-shaped shaft, and the outer circle of the bearing shell is fixed in the bearing shell seat. The utility model has the advantages of reasonable design, simple structure, and convenient operation, can enhances the utilization ratio of equipment, reduces production cost, and extends the service life of the equipment.
Description
The utility model relates to a kind of forcing press accessory, specifically a kind of the forcing press press crankshaft and bearing shell in service life of improving.
The parts that influence forcing press service life mainly are the bent axle and the bearing shell of forcing press, because the position of forcing press stressed maximum when work is exactly bent axle and bearing shell, wearing and tearing between bent axle and the bearing shell make and produce the gap between it, forcing press will stop production to overhaul when excesssive gap, will change bent axle and bearing shell when serious, thereby not only influence is produced and has been reduced the utilization rate of forcing press, and has increased production cost.Also there is not at present good way to solve the problem that forcing press service life is short or maintenance cost is high and utilization rate is low.
The purpose of this utility model provides and a kind ofly prolongs press crankshaft and bearing shell service life, reduces maintenance cost, improves the press crankshaft and the bearing shell of forcing press operating efficiency.
The purpose of this utility model realizes in the following manner, the bent axle of forcing press and bearing shell are designed to diminished shaft and taper watt, in use when diminished shaft and taper watt produce the gap, can adjust the relative position of bearing shell and diminished shaft at any time by being located at bearing shell lid, setscrew nut and locking nut on the bent axle, make it to return to the working clearance of regulation, thereby can avoid the stopping production overhaul of equipment, save maintenance cost and improve usage ratio of equipment.
Accompanying drawing is the structural representation of press crankshaft and bearing shell.
Explain to press crankshaft of the present utility model and below the bearing shell work with reference to Figure of description.
Press crankshaft of the present utility model and bearing shell, its structure is to be made of bent axle 9, bearing shell 3, bush seat 1, bearing shell lid 4, thrust bearing 5, bolt 6 and clamping screw 7, the end of bent axle 9 is provided with a diminished shaft 2, the interior circle of bearing shell 3 is a bellmouth, bearing shell 3 coincide together with diminished shaft 2, and the cylindrical of bearing shell 3 is fixed among the bush seat 1.
The right side of bent axle diminished shaft 2 is provided with one section screw thread platform 8, and locking nut 7 is fixed on setscrew nut 6, thrust bearing 5 and bearing shell lid 4 right part of bearing shell 3 successively.
The cylindrical of bearing shell lid 4 and the interior circle of bush seat 1 right-hand member are provided with screw thread, and bearing shell lid 4 fixes by screw thread and bush seat 1 bearing shell 3 is fixed among the interior circle of bush seat 1.
Embodiment:
Its processing and fabricating of press crankshaft of the present utility model and bearing shell is very simple and convenient, and processing and fabricating both can shown in the by specification accompanying drawing.
In use very simple and convenient to the adjustment in gap between bent axle diminished shaft and the bearing shell, when producing the gap, setscrew nut and locking nut are unclamped, and the turning cylinder FE Tiler moves the major part of bearing shell phase diminished shaft to eliminate then the gap with setscrew nut and locking nut is fixing both can.
Press crankshaft of the present utility model and bearing shell are compared with prior art, have reasonable in design, simple in structure, easy to use, can improve usage ratio of equipment greatly, reduce production costs, the service life of raising equipment, increase characteristics such as economic benefit of enterprises, thereby, have good value for applications.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
