Abstract
The utility model relates to a half-nested dismantling device for an eccentric shaft and belongs to the improving of structure of the half-nested dismantling device for the eccentric shaft. The utility model provides the half-nested dismantling device for the eccentric shaft, which is simple and convenient to operate and causes no damage to components in the dismantling process, and comprises a bracket; the structural key points are as follows: the bracket consists of a transverse rack which can be supported on a bearing, and a vertical rack which can be supported on the eccentric shaft; and an oil cylinder is arranged on the vertical rack, a double-screw bolt is arranged in a piston in the oil cylinder, one end of the double-screw bolt is provided with external threads corresponding to half-nested internal threads, and external threads at the other end of the double-screw bolt penetrate through the piston and then are connected with a nut.
Description
Technical field
The utility model relates to the improvement that eccentric shaft partly overlaps the attaching/detaching apparatus structure.
Background technology
At present, the dismounting mode of the axial region of eccentric shaft dress is mainly that heat is torn open and hot charging, promptly utilizes the principle of expanding with heat and contract with cold, at first bearing inner race is heated, along with the rising of temperature, inner ring begins expanded by heating, when expanding into certain size, utilize external force collision will half cover to pack into or unload again.There is following shortcoming in this mode: the temperature value of (1) heating bearing inner race is difficult for grasping, and the performance of bearing can be influenced because of heating; (2) impact is big or small wayward, and uneven external force can cause the damage of half cover and bearing.
Summary of the invention
The utility model is exactly at the problems referred to above, provides a kind of easy and simple to handle, and the eccentric shaft that in disassembly process part is not had a damage partly overlaps dismantling device.
In order to realize above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, and the utility model comprises support, and its structural feature support is made up of the stand that can be supported in crossbearer on the bearing, can be supported in eccentric shaft; Stand is provided with oil cylinder, is provided with double-screw bolt in the in-oil cylinder piston, and an end of double-screw bolt has the corresponding external screw thread of internal thread with half cover, and the external screw thread of the other end of double-screw bolt passes piston and links to each other with nut.
The beneficial effects of the utility model: because support is made up of the stand that can be supported in crossbearer on the bearing, can be supported in eccentric shaft and stand is provided with oil cylinder, be provided with double-screw bolt in the in-oil cylinder piston, one end of double-screw bolt has the corresponding external screw thread of internal thread with half cover, and the external screw thread of the other end of double-screw bolt passes piston and links to each other with nut; In unloading process, part there is not damage, and easy and simple to handle.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is Fig. 1 right view.
Fig. 3 is the structural representation of the distributor of hydraulic means.
In the accompanying drawing, 1 is eccentric shaft, and 2 is the shaft shoulder, and 3 are stand, and 4 is nut, and 5 is double-screw bolt, and 6 is piston, and 7 is packing ring, and 8 is the expansion type pipe joint, 9 petroleum pipelines, and 10 is oil cylinder, and 11 is support, and 12 is crossbearer, and 13 is bearing, and 14 is half cover, and 15 is distributor.
The specific embodiment
The utility model comprises support 11, and support 11 is made up of the stand 3 that can be supported in crossbearer 12 on the bearing 13, can be supported in eccentric shaft 1; Stand 3 is provided with oil cylinder 10, is provided with double-screw bolt 5 in the piston 6 in the oil cylinder 10, and an end of double-screw bolt 5 has with the corresponding external screw thread of internal thread that partly overlaps 14, and the external screw thread of the other end of double-screw bolt 5 passes piston 6 and links to each other with nut 4.
The petroleum pipeline 9 of the side of oil cylinder is fixed on the distributor 15 by expansion type pipe joint 8, packing ring 7.
For convenient disassembly, stable, four extracting tools of the present utility model can be set evenly on the bearing that is disassembled.
Below in conjunction with a description of drawings course of action of the present utility model: at first, utilize suspender to be fixed in eccentric shaft 1 one sides on support 11, and guarantee that support 11 contacts simultaneously respectively at bearing 13 inner rings and eccentric shaft 1 shaft shoulder 2; Double-screw bolt 5 one ends are fixed in by being threaded in the screw of half cover, 14 sides then; The other end is connected with nut 4, and nut 4 is tightened.Oil pressure is by distributor 15, petroleum pipeline 9, enter in four oil cylinders simultaneously, makes that piston 6 is outer synchronously to be moved; Promptly drive double-screw bolt 5, partly overlap 14 outer moving, till unloading second cover 14.
Otherwise, be loading procedure.
Claims (2)
