The lubrication structure comprises a lubrication sleeve which comprises two parts, namely an upper sleeve and a lower sleeve, the upper sleeve is provided with an upper shaft hole for allowing the mandrel to penetrate through, the lower sleeve is provided with a lower shaft hole for allowing the mandrel to penetrate through, the upper sleeve is provided with two symmetric lubrication grooves, the lower sleeve is provided with an annular groove, and lubricating grease is arranged in the lubrication grooves and the annular groove. Therefore, the vibration motor is simple in structure and convenient and quick to maintain, can be effectively and reliably lubricated, can avoid damage, and prevents a vibration function from being influenced.
Description
Technical field
The present invention relates to a kind of vibration motor with lubrication system.
Background technology
Along with improving constantly of people's living standard, mobile phone is applied more and more extensive in the life of people, and when specifically using, mobile phone often needs to carry out vibrations operation, and this just needs in mobile phone, to install a vibration motor, to shake when needed, and due to the frequency of vibration motor high, the requirement of lubrication is also done, therefore needs a kind of vibration motor that favorable lubricating property can be provided, realize safe and reliable vibrations.
In above-mentioned defect, by concentrating on studies and designing, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research and design goes out a kind of vibration motor with lubrication system, to overcome above-mentioned defect.
Summary of the invention
The technical problem to be solved in the present invention is: because the frequency of vibration motor is high, also does, therefore needs a kind of vibration motor that can provide favorable lubricating property, realize safe and reliable vibrations to the requirement of lubrication.
For solving the problem, the invention discloses a kind of vibration motor with lubrication system, comprise stators and rotators, described stator has for the through central through hole of a central siphon, described rotor is provided with one and is contained in axle in the accommodation space of described central siphon, is provided with lubrication system between described axle and central siphon; It is characterized in that:
Described lubrication system comprises a lubrication sleeve, described lubrication sleeve is made up of two parts, be respectively upper bush and lower sleeve, described upper bush is provided with the upper shaft hole placed for described axle, described lower sleeve is provided with the lower shaft hole placed for described axle, described upper bush is provided with two symmetrically arranged lubrication grooves, and described lower sleeve is provided with annular groove, is provided with lubricating grease in described lubrication groove and annular groove;
Described lubrication groove has the guidance part running through upper bush, and described guidance part is that a breach is circular, and described guidance part is less than the diameter of guidance part towards the width of the opening of axis hole.
Wherein: described guidance part is 1/3 to 2/3 of the diameter of guidance part towards the width of the opening of axis hole.
Wherein: the bottom of described annular groove b is provided with a depression
Wherein: the first end face of described lubrication sleeve is provided with sealing gasket, described sealing gasket is provided with the perforate of passing for described axle.
Known by said structure, the vibration motor structure of band lubrication system of the present invention is simple, and it is convenient to safeguard, effectively can provide the proper lubrication of vibration motor, avoid motor to be damaged, and keeps the function of vibrations to be affected.
Detailed content of the present invention obtains by explanation described later and institute's accompanying drawing.
Accompanying drawing explanation
Fig. 1 shows the schematic diagram of the vibration motor of band lubrication system of the present invention.
Fig. 2 shows the decomposing schematic representation of the vibration motor of band lubrication system of the present invention.
Embodiment
See Fig. 1 and Fig. 2, show the vibration motor of band lubrication system of the present invention.
Described vibration motor 2 comprises stator 23 and rotor 22, described stator 23 has for the through central through hole of a central siphon 21, described rotor 22 is provided with one and is contained in axle 221 in the accommodation space 210 of described central siphon 21, is provided with lubrication system between described axle 221 and central siphon 21.
Described lubrication system comprises a lubrication sleeve 1, described lubrication sleeve 1 is made up of two parts, be respectively upper bush 1a and lower sleeve 1b, described upper bush 1a is provided with the upper shaft hole 10a placed for described axle 221, described lower sleeve 1b is provided with the lower shaft hole 10b placed for described axle 221, jointly to form an axis hole 10, described upper bush 1a is provided with symmetrically arranged two lubrication groove 11a, described lower sleeve 1b is provided with annular groove 11b, described lubrication groove 11a and annular groove 11b forms a lubricating place 11, lubricating grease is provided with in described lubrication groove 11a and annular groove 11b, thus, by the setting of lubricating place 11, make to be lubricated fully during rotor turns.
Wherein, described lubrication groove 11a has the guidance part 112 running through the whole length of upper bush 1a, see Fig. 1, described guidance part 112 is that a breach is circular, described guidance part 112 is less than the diameter of guidance part 112 towards the width of the opening 110 of axis hole 10, it can thus be appreciated that, form tripe shape young greatly in described lubrication groove 11, better to keep lubricating grease.
Wherein, described guidance part 112 is 1/3 to 2/3 of the diameter of guidance part 112 towards the width of the opening 110 of axis hole 10.
Wherein, the bottom of described annular groove 11b is provided with a depression 111, to hold the chip in rotary course, avoids having an impact to rotor.
Wherein, the first end face 12 of described lubrication sleeve 1 is provided with sealing gasket 24, and described sealing gasket 24 is provided with the perforate 240 of passing for described axle 221.
Known by said structure, the vibration motor structure of band lubrication system of the present invention is simple, and it is convenient to safeguard, effectively can provide the proper lubrication of vibration motor, avoid motor to be damaged, and keeps the function of vibrations to be affected.
It is evident that, above description and record be only citing instead of in order to limit disclosure of the present invention, application or use.Although described in an embodiment and be described in the drawings embodiment, but the present invention do not limit by accompanying drawing example and describe in an embodiment as the optimal mode thought at present to implement the specific examples of instruction of the present invention, scope of the present invention will comprise any embodiment of specification and the appended claim fallen into above.
