Abstract
The utility model discloses a novel retaining ring structure of a 2P high-speed large-power motor. The structure comprises two ring assemblies symmetrically arranged on two ends of a rotor respectively. Each ring assembly comprises a retaining ring and an end ring located inside the retaining ring and fixedly connected to a rotor end part. An expanded hole is arranged inside an inner ring hole of the retaining ring, and one of the end holes is arranged inside the expanded hole. The retaining rings and the end rings are in interference fit and are fastened and connected by axially-arranged bolts. The structure is convenient for installation and saves materials. The bolts are used to fix the retaining rings in the structure.
Description
Technical field
The utility model belongs to the novel retaining ring structure of motor 2P high-speed high-power motor.
Background technology
2P high-speed rotary motor, high-power especially 2P motor, rotating speed is high, rotor diameter is large, and it is very large that rotor end ring bears centrifugal force, when designing end ring self undercapacity by calculating when bearing, notch end ring need to increase retaining ring and centering ring is guaranteed end ring safety, but the thick interior band centering ring of conventional design method retaining ring, though also met requirement, loaded down with trivial details and consumptive material is installed in processing.
Utility model content
The purpose of this utility model is to provide a kind ofly cancels centering ring in end ring meeting protection, not only easy for installation but also save material fix the novel retaining ring structure of 2P high-speed high-power motor of retaining ring by screw.
For achieving the above object, the utility model adopts following technical scheme: the novel retaining ring structure of 2P high-speed high-power motor, comprise two ring assemblies that are symmetricly set on respectively two ends of rotor, ring assemblies comprises retaining ring and is positioned at the end ring of retaining ring, end ring is fixedly connected with rotor tip, and the interior annular distance of retaining ring is provided with reaming, and end ring is located in the reaming of retaining ring, retaining ring and end ring are interference fit, and retaining ring is connected by the screw fastening axially arranging with end ring.
Described reaming outer ring the retaining ring wall thickness of corresponding retaining ring part be 5mm-10mm.
Described end ring spacer sleeve is located at the outer ring of rotor shaft, the annular distance diameter of end ring be less than retaining ring annular distance diameter.
The novel retaining ring structure of 2P high-speed high-power motor described in the utility model, retaining ring by interference fit to end ring, then by be located on retaining ring and end ring on screw on corresponding end face mating surface by retaining ring and end ring is fastening is fixed together, meet like this requirement of strength, save the thickness requirement that the centering ring in retaining ring in prior art greatly reduces again the retaining ring wall thickness of the corresponding retaining ring part in reaming outer ring simultaneously, labor and material saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The novel retaining ring structure of 2P high-speed high-power motor as shown in Figure 1, comprises two ring assemblies that are symmetricly set on respectively rotor 5 two ends, axial left and right.
Described ring assemblies comprises that a retaining ring 2 and one are positioned at the end ring 1 of this retaining ring 2, the interior annular distance of retaining ring 2 is provided with reaming, end ring 1 is located in the reaming of retaining ring 2, retaining ring 2 is interference fit with end ring 1, and retaining ring 2 is fastenedly connected by the screw 3 of axial setting with end ring 1, described reaming is for to arrange towards rotor 5, be rotor 5 left ends ring assemblies retaining ring 2 reaming opening to the right, the reaming opening of the ring assemblies retaining ring 2 of rotor 5 right-hand members left, so rotor 5 is between two end ring 1 of two ring assemblies, end ring 1 is fixedly connected with corresponding rotor 5 ends, the axial two ends of rotor 5 are equipped with sliver, sliver is provided with the draw-in groove for fixing end ring, each end ring 1 welds after all embedding the draw-in groove of respective rotor 5 end slivers again, end ring 1 is prior art with the annexation of rotor 5 end slivers, therefore do not describe in detail.Described end ring 1 spacer sleeve is located at the outer ring of rotor shaft 4, between rotor shaft 4 and end ring 1, is provided with gap, the annular distance diameter d of end ring 1 be less than retaining ring 2 annular distance diameter D.
Described reaming outer ring retaining ring 2 wall thickness of corresponding retaining ring 2 parts be 6mm, certainly, novel retaining ring 2 structures of 2P high-speed high-power motor described in the utility model are not limited to above-mentioned form, reaming outer ring retaining ring 2 wall thickness of corresponding retaining ring 2 parts can between 5mm-10mm, all can.
The novel retaining ring structure of 2P high-speed high-power motor described in the utility model, retaining ring 2 by interference fit to end ring 1, then by be located on retaining ring 2 and end ring 1 on screw 3 on corresponding end face mating surface retaining ring 2 is fixed together with end ring 1 is fastening, meet like this requirement of strength, save the thickness requirement that the centering ring in retaining ring 2 in prior art greatly reduces again retaining ring 2 wall thickness of corresponding retaining ring 2 parts in reaming outer ring simultaneously, labor and material saving.
