Description
Technical field
The utility model belongs to the permanent magnet generator machine technology, is specifically related to a kind of hand generator.
Background technology
The said hand generator of the utility model is mainly used in the small-sized hand generator to the power supply of electricity consumption products such as the radio-cassette player with rechargeable battery, mobile phone and illumination.Usually its output voltage is 10V, and electric current is 0.8～1.2A, and rotor speed is 2600～3000rpm.
Succession hand generator for a long time, please join and read the related content in " small and special electric machine is designed program " book of nineteen eighty-three front page publication by Shanghai Science Press, its structure as shown in Figure 1, it mainly is made up of rotor 1, stator module 2 and raising speed gear-driven assembly 3.By understanding accompanying drawing 1, the structure more complicated of the hand generator of the clear this prior art of just being not difficult, preparation cost is higher, is not suitable for and supporting uses such as radio-cassette player, mobile phone and electric lighting.
Summary of the invention
The purpose of this utility model is to provide a kind of compactness rational in infrastructure, and volume is less, and preparation cost is lower, is fit to and matching used hand generators such as radio-cassette player, mobile phone and electric lighting, to solve the existing problem of prior art.
Realize that the technical scheme that the purpose of this utility model is taked is, a kind of hand generator, have stator module, rotor, power outlet and comprise driving gear, driven gear, second driving gear with driving gear engagement and with the two-stage raising speed gear-driven assembly of second driven gear of second driving gear engagement; Second driven gear is fixedly mounted on an end of armature spindle, and its improvement is: also have the mounting panel that is provided with installing hole; The driven gear and second driving gear are mutually integrative-structure; Stator module and bearing interference fit are fixedly connected, and bearing and mounting panel interference fit are fixedly connected; Rotor is fixedly connected by the other end of rotor case and armature spindle, and armature spindle is installed in the bearing center through hole and is rotating; The driving gear kink is in rotating shaft, and rotating shaft and mounting panel are fixedly connected, and the driven gear of one and the second driving gear kink are in its shared rotating shaft each other, and shared rotating shaft and mounting panel are fixedly connected; Lateral surface at driving gear is provided with the power input transmission boss concentric with its axis hole.
Can understand by above given technical scheme, the utility model and prior art compare, it is much simple that its structure is wanted, and volume is also smaller, installs also very convenient, and because gear shaft supports without bearing, also deleted gear housing etc., thereby preparation cost is obviously much lower, particularly because the existence of mounting panel, made things convenient for the installation of said match appliance to link, thereby realized the purpose of this utility model.
Further improvement of the utility model point also is:
Said bearing is an oiliness bearing.And special recommendation is the copper base oil containing bearing, and its preparation cost is more much lower again than the prior art of using ball bearing undoubtedly for this.
On the bearing that adjoins in the side of the side of stator module and mounting panel, be set with packing ring.Certainly, also can not establish packing ring, and allow the mounting panel side directly contact with the coiling packet portion side of stator module, be same passable.But will strengthen the difficulty of mounting panel punching out processing technology like this, also can consume some materials more.
Said driving gear, the driven gear that is mutually one and second driving gear and second driven gear all are plastic gear.And said gear does not need it is implemented reprocessing by single step moulded.Its purpose obviously is in order further to reduce its preparation cost, the driven gear of one and second driving gear especially each other, and by molded, obviously simplified processing process and the material saving of more ground.That is to say, here said plastic gear, with respect to the metal gear of prior art, both are a kind of replacement problem of material anything but, is in order to realize that the utility model further reduces the effective technology measure of purposes such as preparation cost and weight reduction and adopt plastic gear.
After technique scheme is implemented, the compactness rational in infrastructure that it had, easy for installation, assembling is simple, volume is little, in light weight, preparation cost is low, be fit to and matching used characteristics such as radio-cassette player, mobile phone and electric lighting, be conspicuous.
