Definitions
- the present invention relates to the suspension assembly of the motor-compressors units within the tub of a sealed refrigerator compressor.
- the invention is intended to solve all of the above indicated problems and reach a thoroughly stable and silent assembly, based on the technique of suspension through helical springs as above explained. More specifically, the invention relates to the engagement of the springs on the supports of the tub inner walls, with a view of avoiding the beating or tapping between the elements and, furthermore, with the advantage that the machining of the supports is extremely simplified and may be performed by means of simple stamping, pressing and
- the support hole is formed by means of a deformation of the borders of this latter such that it assumes a closed helical profile of a single screw thread pitch the ends of which are located at different levels, mutually close and joined by a short longitudinal run, whereas at the same time a protruding stop is formed in the support, as well by deformation of its material, to limit the penetration of the spring end into the support.
- the spring penetration stop may be obtained through very diverse manners, for example by embossing a tenon to protrude from the upper face of the support, by punching and rising a fin of the support material, or by a protruding deformation of the run joining the two ends of the helical pitch defined by the edges of the support opening.
- the borders of the support opening in which the said turns are screw thread engaged can be formed with a profile of several shapes such as inclined surfaces, preferably symmetric, straight or curvilinear, upon which the spring turns will perfectly seat from both support sides.
- the suspension shown in the drawings is of the type in which a spring R is screw thread engaged by one its ends in the opening A, tapped or formed to mate the outer surface of the spring end, of a support S which is fitted on the inside of the walls of the tub C of a moto-compressor unit, whereas its opposite end is engaged in an orifice O formed in the body of the unit stator E such that it conforms as well to the spring end outer surface.
- the opening A of the metal plate support S in which the wires of the helical spring R are to be screw thread engaged is formed by giving to it a helical profile extending over a single pitch or turn 1. To this end the border of said opening is deformed, with no cutting of the support metal plate, such that it assumes a progressive circumferential inclined surface between two opposite points 2,3 of its periphery, close with one another though mutually spaced apart in the axial direction of the opening and joined by a short intermediate plate material run 3a (see Fig. 4 and 5).
- the border 1 of the opening A is advantageously beveled or tapered on at least one edge, either in an inclined surface, as seen in Figures 5 and 8, or in arcuate or merely stepped shape as shown, respectively in solid and dotted lines in Figure 9, with the purpose of facilitating the entrance of the turns of the spring R.
- a tenon 4 is stamped from the material of the support S to protrude from the upper face of this latter at a short distance of the edge of opening A, against which the outwards bent end 5 of the spring R will impinge when the spring is inserted in the opening, to limit the insertion length of the spring end engaged in the opening A of the support S.
- the stop in question can also be formed by merely rising a vertical fin 6 (Fig. 10), an inclined fin 7 (Fig. 11), or under a deep deformation of the material run 3a joining the two ends 2,3 of the helical pitch 1 of the opening A, thus forming in the same a protruding angle 3b (Fig. 12).
- the deformation of the walls of the opening A can be effected such that the helical pitch formed by the edges of said opening are terminated at its front part (Fig. 1 and 14) or, with just the same result, at its rear part, as shown in the embodiment depicted in Figures 13 to 15.
- the support S may form an independent piece which is removably engaged on a shoulder and fixed to the wall inner surface of the tub C, or made of a single piece directly joined to the tub walls in a fast manner.
- the obtained advantage resides on the fact that the spring wires are firmly retained in the helical pitch 1 of the opening A, with no risk that the normal vibration caused by the to and fro motion of the compressor piston can escape, thus preventing any kind of beating or tapping.
