Abstract
The utility model discloses a motor bearing fixed structure, including an end cap, a bearing, and a combination screw, wherein the bearing chamber end face of the end cap is provided with a screw fixed hole, and the combination screw is arranged in the screw hole of the end face of the end cap bearing chamber to press the outer ring of the bearing. The motor bearing fixed structure is characterized by simple structure, low cost, and efficient assembly man-hour, and bringing convenience for maintenance and disassembly of the bearing.
Description
Technical field
The utility model relates to the structure field of motor, specifically a kind of fixed structure of motor bearings.
Background technology
Usually, the bearing of motor is mounted in the bearing chamber of electric motor end cap, but because the rotor of motor is rotor, run up through being everlasting, also be subject to the effect of the external force such as impulsive force of load, just might move towards the end face direction of bearing chamber, this just need to limit the cycle surface of bearing.At present, have plenty of and push down bearing outer ring with trim ring and then with screw trim ring and bearing chamber are fixed together, have like this expense cost that increases trim ring; Have plenty of that the end face at bearing chamber reserves a circle when the machining bearing chamber, the circle that the method for utilization extrusion reserves end face encases the end face of bearing outer ring, this exists irreversible defective, namely as will split out bearing and must destroy and encase bearing outer ring one loop material and bearing could be taken out.
Summary of the invention
The utility model is for fear of the existing weak point of above-mentioned prior art, a kind of motor bearings fixed structure is provided, so that bearing outer ring had both had the effect of axial restraint, again can be under the prerequisite of not destroying the bearing chamber end face removablely go out bearing, but and cost-saving.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of motor bearings fixed structure, comprise end cap, bearing, screw assemblies, the bearing chamber end face of described end cap is provided with screw fixed hole, and described screw assemblies is contained in the outer ring of pushing down bearing in the screw of bearing with end cover chamber end face.
Described screw assemblies is comprised of screw and butterfly gasket, and the coiled hair set of locations that the end face of butterfly gasket is in screw is integral.
The bearing chamber end face axial height of described end cap is lower than and is pressed into bearing rear bearing cycle surface 0.1～0.5mm.
The bearing chamber cylindrical is protruded at the screw fixed hole place of the bearing chamber cylindrical of described end cap, is convenient to the setting of screw hole.
The screw fixed hole of the bearing chamber end face of described end cap and the quantity of screw assemblies all are 3～4.
Compared with prior art, the utility model has the advantage of, utilize pad to replace trim ring, provide cost savings, when saving the assembler again, have simultaneously the repair demolition bearing conveniently, characteristics simple in structure.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is plan structure figure of the present utility model.
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Such as Fig. 1, shown in Figure 2, a kind of motor bearings fixed structure, comprise end cap 1, bearing 2, screw assemblies 3, at first bearing is pressed into when mounted in the bearing chamber of end cap 1, then screw assemblies 3 is screwed in the screw fixed hole of bearing chamber end face of end cap 1, screw assemblies 3 is tightened the assembling that to finish total, because screw assemblies 3 is combined into one by screw 31 and butterfly gasket 32, so assemble up convenient, butterfly gasket 32 has spring function simultaneously, can play the phenomenon that prevents that screw assemblies 3 is loosening, make bearing shaft to fixing more reliable.
Above-described embodiment is not the restriction to the utility model rights protection just to a kind of explanation of the present utility model.
