Description
Technical field
The utility model relates to a kind of motor, is specifically related to the electric machine structure that a kind of outside regulates end play.
Background technology
Permanent magnet DC motor has good mechanical property and regulating characteristics, and it has, and volume is little, efficiency is high, rotation speed change scope large, have larger detent torque, exciting method simple, moderate, and the feature that other forms cannot substitute.Along with the development of national economy and the raising of living standards of the people, also more and more higher to the instructions for use of motor, require also more and more stricter to motor noise.Because axial clearance of motor is crossed, conference makes the vibrations of motor, noise becomes large, make motor can not stable operation, affect the useful life of motor, so how designing good, an easy axial clearance regulation structure is very important for the use of motor and the operating efficiency of factory simultaneously.
Summary of the invention
The utility model object is: for the problems referred to above, the utility model provide a kind of can at the electric machine structure of outside regulating shaft to gap.
The technical solution of the utility model is: a kind of outside regulates the electric machine structure of end play, comprise and casing, with the end cap that casing riveting is fixing, be arranged on the rear oiliness bearing on end cap, be arranged on the front oiliness bearing on casing, and the rotor to match with described rear oiliness bearing and front oiliness bearing, described rotor comprises its one end and stretches out armature spindle outside described casing, described rotor axle sleeve is provided with the Front oil seal circle matched with the inner surface of described front oiliness bearing, the Rear oil seal circle matched with the inner surface of described rear oiliness bearing, and the washer sets to match with the outer surface of described front oiliness bearing, and described washer sets is positioned at described casing outside, the polyphenyl packing ring that described washer sets is arranged from inside to outside successively, rubber washer, stop washer and split washer are formed, thus by the polyphenyl packing ring quantity in the described washer sets of change before changing, Rear oil seal circle and front, gap length between rear oiliness bearing.
On the basis of technique scheme, comprise following attached technical scheme further:
The quantity of described rubber washer, stop washer and split washer is one, and the quantity of described polyphenyl packing ring is one or more.
Described split washer card is established and is fixed on described armature spindle.
The utility model has the advantages that: this motor of the utility model is arranged in outside motor by being used for regulating the washer sets of end play, only have front oiliness bearing to coordinate with washer sets simultaneously, therefore the motor mechanism of motor internal is arranged on compared to washer sets in the past, when workman carries out end play adjustment and reprocesses, operate simpler, and only have side to be added with washer sets, thus reduce the production cost of motor.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is this overall structure schematic diagram with the motor that oiliness bearing directly contacts with oil seal washer of the utility model embodiment;
Fig. 2 is the structural representation of polyphenyl packing ring in the utility model embodiment;
Fig. 3 is the structural representation of rubber washer in the utility model embodiment;
Fig. 4 is the structural representation of stop washer in the utility model embodiment;
Fig. 5 is the structural representation of the utility model embodiment split shed back-up ring;
Wherein: 1-washer sets, 2-armature spindle, oiliness bearing before 3-, 4-rotor, 5-casing, 6-end cap, 7-Front oil seal circle, 8-Rear oil seal circle, oiliness bearing after 9-, 10-polyphenyl packing ring, 11-rubber washer, 12-stop washer, 13-split washer.
Embodiment
Embodiment: Fig. 1 ~ Fig. 5 illustrates the specific embodiment that this outside of the utility model regulates the electric machine structure of end play, this motor is permanent magnet DC motor, it comprises rotor 4, casing 5 and the end cap 6 fixing with casing 5 riveting, wherein end cap 6 is provided with rear oiliness bearing 9, casing 5 is provided with front oiliness bearing 3, front oiliness bearing 3 and rear oiliness bearing 9 all match with described rotor 4.Rotor 4 comprises armature spindle 2, and casing 4 outside is stretched out in one end of this armature spindle 2, is referred to as the outer end of armature spindle 2.
The key improvements of the present embodiment is: on armature spindle 2, fixed cover is provided with Front oil seal circle 7 and Rear oil seal circle 8, and Rear oil seal circle 8 described in the inner surface of described rear oiliness bearing 9 matches (inner side that Rear oil seal circle 8 is positioned at rear oiliness bearing 9), the inner surface of described front oiliness bearing 3 matches with described Front oil seal circle 7 (inner side that Front oil seal circle 7 is positioned at front oiliness bearing 3).Armature spindle 2 is also arranged with the washer sets 1 (washer sets 1 is positioned at the outside of front oiliness bearing 3) matched with the outer surface of described front oiliness bearing 3, and washer sets 1 is positioned at casing 5 outside." inner surface " and " outer surface " of front oiliness bearing 3 mentioned here, refers to the axial medial surface of front oiliness bearing 3 and axial lateral surface respectively.
Described washer sets 1 is arranged in the outer end of armature spindle 2, it is made up of jointly multiple armature spindle 2 upper gasket monomer that is enclosed within, these packing ring monomers are followed successively by polyphenyl packing ring 10, rubber washer 11, stop washer 12 and split washer 13 from inside to outside, wherein polyphenyl packing ring 10 directly directly contacts with the outer surface (or claiming lateral surface) of front oiliness bearing 3, the quantity of polyphenyl packing ring 10 can be one, also can be multiple.Split washer 13 is fixedly fastened in draw-in groove shaping on armature spindle 2, thus polyphenyl packing ring 10, rubber washer 11, stop washer 12 is tightly clipped between front oiliness bearing 3 and split washer 13.When embody rule, the end play (making that there is between them rational end play value) on rotor 4 between front and rear oil seals circle 7,8 and front and back oiliness bearing 3,9 can be changed by the quantity changing polyphenyl packing ring 10 in described washer sets 1, avoid axial clearance of motor excessive and the motor vibrations, the noise that cause become large, ensure the stable operation of motor, improve the useful life of motor.
In this example, described washer sets 1 is only present in the outer end of armature spindle 2.During for regulating the end play between front and rear oil seals circle 7,8 and front and back oiliness bearing 3,9, be only limited to the quantity increase and decrease of polyphenyl packing ring 10, the quantity of rubber washer 11, stop washer 12 and split washer 13 is constant all the time, is only limited to one.
Certainly, above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to people can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection range of the present utility model.
