Application filed February 5,
This invention relates to electric motors, and more particularly to motors of a character presenting a rotating surface exteriorly, and it is among the objects of the inven tion to provide a construction presenting a rotatable peripheral surface and yet with a compact motor-mounting such that the motor is entirely contained within the roller. Another object is the provision of ventilation means for rotary-surface motors thereby inhibiting over-heating tendencies. Other objects and advantages will appear as the description proceeds.
To the accomplishment of the foregoing and related ends, the invention, then, com prises the features hereinafter fully described, and particularly pointed out in the claims, the following description and the annexed drawing setting forth in detailcertain illustrative embodiments of the invention, these being indicative however, of but a few of the various ways in which the principle of the invention may be employed.
In said annexed drawing Fig. 1 is a front elevational view of a motor in accordance with the invention; Fig. 2 is a horizontal axial section, on a large scale, taken on a plane substantially indicated by the line 11-11, Fig. 1; Fig. 3 is an end view; Fig. 4 is a front elevational view of a modified form; and Fig. 5 is an isometric view of an assembly of units.
Referring more particularly to the drawing, there is shown a cylindrical roller 2 having a motor-rotor 3 internally secured to the shaft l, which passes through the motorstator and housing 5. The outer roller surface is in sections, each keyed or suitably fastened to the respective ends of the shaft 4 to rotate therewith. The stator-housing 5 is fastened to a support 6 which is sufficiently narrow to project between the roller sections, and which may have a width to generally correspond with the stator. The support 6 is fixed torthe stator-housing suitably, as for instance by welding or riveting, and may be provided with an expanded foot-portion 7 having bolt-holes 8 for fastening to its point of support. A support of great strength resistive against various operating stresses may 1932. Serial No. 591,138.
behad in this general manner, and occupymg a negligiblespace axially and permitt ng 7 free access to the various portions of the rotating outer surface, Where rollers of some length are desired, three or more sections 2a, 4, may be arranged, a support 6a being then positioned between adj acent sections, the shaft being connected-to the sections. Two or more motor-rotors 3a may correspondingly be provided, if desired. Irrespective of the number of rotor windings in any unit, it will be observed that the leads a in any casemay be I arranged very conveniently, to. pass through the opening between the roller sections .{V I
The sections of the roller 2 may preferably have openingsin the end, and these. may take the form of cuteouts 9 between spoke-portions 10 which connect theperiphery of the roller with the hub 11 that is fastened to the shaft. While a satisfactory ventilation may be had in some cases by such openings, generally, it is preferable to shape the spokes 10 with a suflicient angular propeller-type surfacing to positively force air through the pass-ways between the roller and the internal portions. The pitch ofthe spoke-bladi'ng 10 may be complemental on theitwo ends, that is, one set of. spokes being pitched to force air in, and the spokes at the other end being pitched to force the air out, or both sets of spokes may be pitched to force air in the same direction in'or out.. In'any'case, it will be seen that by reason of the space intermediate between the sections of the roller, a further favorable factor in. the I ventilation system is had, Motors constructed inaccordance with the present invention are accordingly capable of highly favorable cooling action, consid:
ering the natural handicap which such a,
by a lubricating cup 14L may be readily a ag d o commu i ate wi h the b arings, notwithstanding the closely housed-in general construction.
An advantage of this type of construction is that the motor and roller require no greater axial distance than the roller alone. The
applicability of such motor construction will be readily apparent. The individual units may be used as such in situations where an external rotating surface is wanted, and the port is not wide enough to be detrimental to material being conveyed over the roller, and in effect the sections of the roller function as one roller. It will be understood also that the surface of the roller may be variously shaped as desired in view of the particular duty contemplated. For instance, thesurface may be curved to more or less fit the shape of pipe, where such units are to be used for conveying pipe. By arranging a series of the motor units in adjacent relation with each other, as indicated in Fig. 5, a continuous traveling table surface may readily be had, in a manner especially favorable for usage in steel mills and metal-working plants, etc. And in general,as readily apparent, desired combinations in assembly may be variously arranged.
Other modes of applyingthe principle of the invention may be employed, change being made as regards the details described, provided the means stated in any of the following claims, or the equivalent of such, be employed. I
I therefore particularly point out and distinctly claim as my invention 1. A- device of the; character described, comprising a roller in a plurality of axially adjacent spaced-apart sections, a plurality of driving motors therewithin, a common'shaft in said motors connected to the roller-sections, each motor having a rotating portion connected to the shaft and a stationary portion,
and a support attached to the stationary por tion of each motor and projecting through the space between roller sections.
2. A device of the character described, comprising a roller, a driving motor therewithin, said motor including a rotating portion extending axially to connect to the roller and a stationary portion, bearings for the rotating portion of the motor, duct-means extending from outside the roller tosaid bearings, and a support for the motor projecting through a transverse interruption in the roller-surface.
- 3. A device of the character described, comprising aroller, a driving motor therewithin, said motor including a stator and a rotor and a shaft connected to the roller,
bearings in the motor for said shaft, bores extending from the ends of the shaft to the bearings, and a support forthe motor projecting through a transverse interruption in the roller.
