Description
Technical field
The utility model relates to retarder, is specifically related to a kind of spiral gear planet wheel speed reducer.
Background technique
Epicyclic transmission mechanism is generally used for the occasion of low-speed heave-load, is widely used in industries such as metallurgy, building materials, electric power.Along with the develop rapidly of production technology, the transmitted power of planetary gear mechanism is increasing, and requires the volume of driving mechanism, weight more and more littler, and reliability and demands for bearing capacity are also increasingly high.Relative helical teeth of diclinic tooth epicyclic transmission mechanism and straight-tooth have more superiority, to satisfy the demand for development of epicyclic transmission mechanism.Diclinic tooth epicyclic transmission mechanism commonly used, as shown in Figure 2, to form by sun gear 1, many planet wheels 2 and internal gear 3, many planet wheels 2 are installed on the planet carrier 5 through each planet wheel shaft 4.Sun gear 1 is provided with rotation direction opposite helical teeth 1a, 1b, and planet wheel 2 is provided with rotation direction opposite helical teeth 2a, 2b, and internal gear 3 is made up of two opposite spiral gear 3a, 3b of rotation direction.Helical teeth 1a on the sun gear 1,1b respectively with many planet wheels 2 on helical teeth 2a, 2b engagement, the helical teeth 2a on many planet wheels 2,2b respectively with internal gear 3 on two double helix gear 3a, 3b engagement.Internal gear 3 is arranged to be made up of two opposite helical teeth 3a, 3b of rotation direction, and the spiral gear 3a that its two rotation direction is opposite, the angular pitch of 3b equate from returning the cutter slot length with people's tooth of sun gear 1 and planet wheel 2, its objective is easy for installation for internal gear 3.
The subject matter that this structure exists is: the herringbone tooth on (1) processing sun gear and the planet wheel is cumbersome, after processing helical teeth on one side, needs centering could process the opposite helical teeth of rotation direction of another side; (2) the processing herringbone tooth can stay the long cutter groove that returns between the opposite helical teeth of rotation direction, and the volume of epicyclic transmission mechanism is increased; When (3) processing long gear, very strong to the dependence of equipment.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, and a kind of centering that do not need is provided, and volume is less relatively and to device dependence small helical gear planet wheel speed reducer.
For realizing above-mentioned purpose, the technological scheme of the utility model is a kind of spiral gear planet wheel speed reducer of design, and said speed reducer comprises sun gear, planet wheel and internal gear; Said planet wheel is installed on the planet carrier through planet wheel shaft; It is characterized in that described sun gear comprises two spiral gears that size is identical, rotation direction opposite, tooth portion parameter is identical, said planet wheel comprises that two sizes are identical; The spiral gear that rotation direction is opposite, tooth portion parameter is identical; Said internal gear comprises that two sizes are identical, the spiral gear that rotation direction is opposite, tooth portion parameter is identical, two double helix gears on the said sun gear respectively with planet wheel on two double helix gear engagement; Two double helix gears on the said planet wheel respectively with internal gear on two double helix gear engagement; Two double helix gears of said sun gear connect through fastening piece, and two double helix gears of said planet wheel connect through fastening piece, and two double helix gears of said internal gear connect through fastening piece.
Wherein, described internal gear is connected through fastening piece with casing, and described planet wheel two ends are provided with roller bearing or sliding bearing.
The advantage and the beneficial effect of the utility model are: because this spiral gear planet wheel speed reducer has adopted spiral gear; Except that have helical teeth planet wheel speed reducer take up room little, bearing capacity is high, the complete machine transmission efficiency is high, all characteristics of long service life, also have more beneficial effect:
1, sun gear, planet wheel and internal gear spiral gear identical by size respectively, that rotation direction is opposite is formed, and the processing spiral gear is simple more, convenient, and need not need centering as the processing herringbone tooth.
2, process spiral gear separately and need not return the cutter groove as the processing herringbone tooth, it is much little that its sun gear of assembling back, planet wheel and internal gear helical teeth end distance are returned the cutter slot length relatively, and under the situation of transmitting same power, its volume is less relatively.
3, because herringbone tooth is divided into two, the length of its spiral gear has reduced half the, and its dependence to process equipment also reduces greatly, has improved the processing versatility.

Fig. 2 is the common diclinic tooth planetary speed reducer structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
As shown in Figure 1, the utility model is a kind of spiral gear planet wheel speed reducer, mainly is made up of sun gear 1, planet wheel 2 and internal gear 3, planet wheel shaft 4, planet carrier 5, casing 6.Planet wheel 2 is connected on the planet axis 4 through interference, is installed on the planet carrier 5.Sun gear 1 is made up of two spiral gear 1a, 1b that size is identical, rotation direction opposite, tooth portion parameter is identical; Planet wheel 2 is made up of two spiral gear 2a, 2b that size is identical, rotation direction opposite, tooth portion parameter is identical, and internal gear 3 is made up of two spiral gear 3a, 3b that size is identical, rotation direction opposite, tooth portion parameter is identical.Two double helix gear 1a on the sun gear 1,1b respectively with planet wheel 2 on two double helix gear 2a, 2b engagement, two double helix gear 2a on the planet wheel 2,2b respectively with internal gear 3 on two helical gear 3a, 3b engagement.Two double helix gear 1a of sun gear 1,1b are fixed together through fastening piece, and two double helix gear 2a of planet wheel 2,2b are fixed together through fastening piece, and two double helix gear 3a of internal gear 3,3b are fixedly connected through fastening piece.
Sun gear 1, planet wheel 2 and internal gear 3 all adopt spiral gear, can reduce difficulty of processing, adopt general manufacturing equipment just can process.With respect to straight-tooth and monocline tooth epicyclic transmission mechanism, under the situation of transmitting equal-wattage, volume energy reduces 15%; Still leave small boss between the two helical gear ends shown in Fig. 1; Mainly be the arts demand that is limited to present processing end face, be generally several millimeters, at most also be no more than 5mm; With respect to common helical tooth human relations epicyclic transmission mechanism double helical tooth to return the cutter slot length much smaller, its volume also reduces relatively; Technological development in the future, end face can not reserved small boss fully.Simultaneously, the processing spiral gear also reduces the dependence of equipment greatly, has improved the processing versatility.
