Abstract
The utility model discloses a motor revolving shaft frame which is composed of a motor shaft installing hole and bilateral installing arms and is characterized in that the internal motor shaft installing hole is internally provided with a bearing which is molded with a motor revolving shaftframe as a whole. The utility model molded the bearing or a shaft sleeve with the motor revolving shaft frame according to certain assembling location requirement as a whole without extra installation, thereby accurately fixing a rotator on the motor stator and thoroughly overcoming the eccentricity or deformation as a result of the fact that the bearing or the shaft sleeve is pressed in the revolving shaft frame and ultimately improving the assembling precision of the motor efficiently, furthermore, the utility model also has the advantages of reduction of both vibration and noise.
Description
Technical field
The utility model relates to a kind of machine shaft support.
Background technology
The prior motor rotary shaft rack includes only the installation support arm 1 that motor shaft is sent out dress hole 2 and both sides as shown in Figure 1, 2.The machine shaft support at first must be pressed into motor shaft installing hole 2 internal fixation of machine shaft support to bearing or axle sleeve before installation, so is easy to cause the eccentric or distortion of support, causes the motor assembly precision not high, produces vibrations and noise.In addition, both sides installation support arm 1 and motor shaft installing hole 2 be shape linearly, support arm 1 end is installed is provided with fixing hole 11.As shown in Figure 3, motor main body 7 both sides are connected with gas chamber shell 9 by machine shaft support 6, run through gas chamber shell 9, machine shaft support 6 and motor main body 7 by bolt 8, fix 3 during installation.The whole generation shaken when motor 7 rotates, because the installation support arm 1 of machine shaft support 6 and motor shaft installing hole 2 be shape linearly, and that motor main body 7, machine shaft support 6 and gas chamber shell 9 that three fixing points linearly (two ends fixing hole 11 and motor shaft installing hole 2) orders links together are easy to produce is loosening, causes reliability lower.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of machine shaft support, and it can improve the motor assembly precision, reduces vibrations and noise.
The purpose of this utility model is achieved in that a kind of machine shaft support, comprises the installation support arm of motor shaft installing hole and both sides, it is characterized in that: be provided with in the described motor shaft installing hole with machine shaft and prop up the bearing that the shut die notes are combined into one.
Described machine shaft support is the U type.
Described every side is installed support arm and is provided with two or more fixing holes.
Described fixing hole comprises two, is located at every side respectively the terminal of support arm and bending position are installed.
The utility model by bearing or axle sleeve and machine shaft support by certain assembling and positioning requirement, the mould notes are combined into one, and once finish the manufacturing, and rotor is fixed on the motor stator exactly.Thoroughly solve bearing or axle sleeve and be pressed into caused off-centre of rotary shaft rack or distortion, improve the motor assembly precision effectively, and play the damping noise reduction effect.

Embodiment
Shown in Fig. 4,5, the utility model is a kind of machine shaft support, comprises the installation support arm 3 and the bearing 4 of motor shaft installing hole 2, both sides.
Bearing 4 is annotated with machine shaft carriage motor axle installing hole 2 moulds and is combined into one.After earlier bearing or axle sleeve being fixed on mould during making, the high-temperature resistance plastice that reinjects (as glass fibre, poly-charcoal etc.), bearing 4 and machine shaft support are one-body molded, and both combine closely.
The machine shaft support is the U type, and wherein the installation support arm 3 of every side is provided with two or more fixing holes, for example comprises two fixing holes in the present embodiment, is respectively to be located at the fixing hole 31 that every side is installed the fixing hole 32 of support arm 3 ends and bent the position.This structure makes original line fixedly become face and fixes, and connects more firmly, even assembling back can not become flexible through running for a long time yet, reliability, fail safe improve greatly, and more the proper operation support is fixing.Be specially adapted to the application on beauty appliance and medicine equipment.
As shown in Figure 6, motor main body 7 both sides are connected with gas chamber shell 9 by machine shaft support 10, because the every side in the machine shaft support 10 is installed support arm 3 and is provided with two fixing holes 31,32, so it has four bolts 8 to run through gas chamber shell 9, machine shaft support 10 and motor main body 7, fixes (showing one-sided in the drawings) with 3.Form rectangular surfaces by four fixing points and connect, stressed even, thus be difficult for being shifted, getting loose.In addition, the rotating shaft 5 of motor main body 7 runs through the motor shaft installing hole 2 and the gas chamber shell 9 of machine shaft support 10.
Claims (4)
