Abstract
The utility model relates to a front-end cover of a magnesium-alloy motor. The outer end surface of the front-end cover is an installing plane connected with a speed reducer; and a shaft hole is formed at the center of the installing plane. The front-end cover is characterized in that the front-end cover of the motor is made of magnesium alloy; and a circumferential indent shoulder is coaxially arranged around the shaft hole on the installing plane. The front-end cover has the beneficial effects that compared with the conventional product made of aluminum alloy, the front-end cover has the advantages of light weight, high strength, less elastic modulus, good rigidity and strong shock resistance, improves the whole performance of the motor and can meet the need in various application occasions such as lifting equipment; in addition, since the circumferential indent shoulder is added on the basis of the conventional structure, when a positioning jig and a pressing plate are combined for processing, the pressing plate only needs to be pressed on the indent shoulder without twice clamping, and the processing of the inner-side plane and the outer-side plane of the installing plane is finished by one step, so that the processing steps are reduced and the processing efficiency is improved.
Description
Technical field
The utility model relates to a kind of motor part, relates in particular to a kind of Mg alloy electric machine front end housing.
Background technology
Motor is widely used in all trades and professions as driven by power equipment.The motor front end housing is the important composition part of motor.Existing its inner face of motor front end housing be provided with housing be connected seam and bearings cover, the outer face is for connecting the mounting plane of reductor, its structural behaviour directly influences the motor overall performance.The defective that existing motor front end housing exists is: (1) front end housing adopts cast aluminium alloy to make; And with the cast aluminum casings motor housing that forms a complete set of; Make the motor preponderance; The use needs that especially can not adapt to the lifting means in fields such as building, machinery, and cast aluminium alloy intensity, elasticity, rigidity, shock resistance is all not good enough.In addition; The outer face of motor front end housing is as the mounting plane that connects reductor; Its central authorities are provided with axis hole, are provided with the seam that the annular flange conduct is connected with reductor around axis hole is coaxial, and annular flange is separated into inboard plane and outer side plane two parts with mounting plane.Because existing motor front end housing structure does not have the position, card division of pressure, the processing method of mounting plane is to adopt positioning clamping fixture to combine with pressing plate at present, carries out in two steps; At first positioning clamping fixture is supported on the inner face of motor front end housing, presses the bight of the outer side plane of mounting plane earlier with pressing plate, process inboard plane with lathe tool; Press the inboard plane of mounting plane to process outer side plane with pressing plate then with lathe tool; Twice operation palpus swivelling tool-holder, complex operation, working (machining) efficiency is low.
The utility model content
The main purpose of the utility model is to the problems referred to above, and a kind of Mg alloy electric machine front end housing that on the prior art basis, improves material and structure is provided, and improves its performance and simplifies the course of processing, improves working (machining) efficiency.
The utility model solves the technical scheme that its technical problem adopted:
A kind of Mg alloy electric machine front end housing, its outer face are the mounting plane that is connected with reductor, and the mounting plane center is an axis hole, and the material that it is characterized in that said motor front end housing is a magnesium alloy; On said mounting plane, encircle all indent shoulders around coaxial setting of said axis hole.
The beneficial effect of the utility model is: because the motor front end housing adopts the magnesium alloy material; With existing aluminum alloy material ratio have in light weight, intensity is high; Modulus of elasticity is little, good rigidly and the strong advantage of shock resistance; Improve the motor overall performance, and can satisfy various application scenarios needs such as lifting means; In addition, on the existing structure basis, set up all indent shoulders of ring, adopted positioning clamping fixture to combine to add man-hour with pressing plate; Only need pressing plate is pressed onto on the indent shoulder, need not be installed for twice, a step is accomplished the inboard plane of mounting plane and the processing of outer side plane; Reduce procedure of processing, improve working (machining) efficiency.
Description of drawings
Fig. 1 is the main TV structure sketch map of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1 mounting plane, 2 annular flange flange seams, 3 inboard planes, all indent shoulders of 4 rings, 5 outer side planes, 6 axis holes, 7 bearing holder (housing, cover)s, 8 housings connect seam.
Below in conjunction with accompanying drawing and embodiment the utility model is specified.
Embodiment
Fig. 1～Fig. 2 illustrates a kind of Mg alloy electric machine front end housing; Its outer face is the mounting plane 1 that is connected with reductor; The mounting plane center is an axis hole 6, is provided with annular flange flange seam 2 around axis hole 6, and the front end housing inner face is provided with bearing holder (housing, cover) 7; Housing connects seam 8, and its characteristic is a magnesium alloy in the material of above-mentioned motor front end housing.Owing to adopt the magnesium alloy material, with existing cast aluminium alloy material ratio can realize in light weight, intensity is high, modulus of elasticity is little, good rigidly, advantage that shock resistance is strong, has improved the motor overall performance, can be used for various application needs such as lifting means.
The architecture advances of motor front end housing is embodied on above-mentioned mounting plane 1 around the axis hole 6 coaxial all indent shoulders 4 of ring that are provided with.As shown in the figure, annular flange flange seam 2 is separated into inboard plane 3 and outer side plane 5 two parts with mounting plane 1, because coaxial being provided with encircled all indent shoulders 4 in axis hole 6 outsides; When the installation and processing plane; At first positioning clamping fixture is supported on the inner face of motor front end housing, then pressing plate directly is pressed in the indent shoulder 4, but make the inboard plane 3 of mounting plane all be in machining state with outer side plane 5; Need not be installed for twice; Once be installed and accomplish whole processing of mounting plane 1, reduce procedure of processing, improve working (machining) efficiency.
Above content is not that structure, shape to the utility model done any pro forma restriction.Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
