Background technique
At present, in field of metallurgical equipment, single roller-way transmission progressively substitutes concentrated transmission, and this kind kind of drive has been improved the situation that causes whole equipment stopping production in the concentrated transmission because of the problem of a certain link greatly.In existing single roller-way transmission, the main transmission device that uses is single electric machines for roller retarder.
Its retarder adopts the principle of multistage hard flank of tooth column gear transmission mostly in existing single electric machines for roller retarder.In column gear transmission, single-stage driving is less, but owing under same boundary dimension, will reach identical velocity ratio, so progression is more, module just needs to select less modulus, to reach higher bearing capacity simultaneously, just necessarily require tooth face hardness higher, increase the manufacture difficulty of gear for this reason.Simultaneously, for increasing contact strength, adopt the helical gear of non-standard helix angle more, cause transmission efficiency to reduce, and because modulus is less, and its internal gear spare part just can not bear than high impact loads, so manufacture cost is high, maintenance rate is high, user cost is high.
The model utility content
The purpose of this utility model is to provide in order to solve above-mentioned the deficiencies in the prior art that a kind of bearing capacity is high, single electric machines for roller retarder of the dotted line transmission of stable drive.
To achieve these goals, single electric machines for roller retarder of the dotted line transmission that the utility model is designed, comprise casing, place the gear-driven assembly in the casing and the motor that is fixedly connected with gear-driven assembly, it is characterized in that described gear-driven assembly comprises that power input gear, symmetry terminal and that motor is fixedly connected with are located at the gearwheel of power input gear both sides and pinion shaft, the power output gear that is meshed with pinion shaft and for the output shaft that is socketed power output gear; Power output gear is that key is connected with the Placement of output shaft; The symmetrical engagement of described gearwheel and power input gear, and gearwheel is that key is connected with the Placement of pinion shaft; Pinion shaft and power input gear are an involute displacement stub-tooth gear, and power output gear and gearwheel flank profil top adopt the involute double wedge wide, and the recessed flank profil of transition curve is adopted in the bottom.
For pinion shaft is fixed on the casing, be provided with the tapered roller bearing that is socketed on the pinion shaft at the pinion shaft two ends, this bearing not only can bear radial load but also can bear thrust load.
In order to adapt to single roller-way transmission and to avoid the high limited situation in center, the axis parallel of pinion shaft and output shaft, and the center of pinion shaft is just high in the center of output shaft.
Single electric machines for roller retarder of the dotted line transmission that the utility model obtains utilizes the point-line meshing gear transmission principle, improves retarder running-in characteristic and touch strength of gear and increases the retarder single staged transmission ratio; Adopt the kind of drive of power dividing point-line meshing gear group, make the retarder transmission more steady, reduce the load that monodentate bears, also improve the bearing capacity of retarder simultaneously, make its longer service life; Adopt the direct-connected retarder manufacture cost that makes of motor shaft to reduce, structure is compacter.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment:
Single electric machines for roller retarder of the dotted line transmission that the present embodiment provides, comprise casing 1, place the gear-driven assembly 2 in the casing 1 and be fixedly connected with and place the outer motor 3 of casing 1 with gear-driven assembly 2, described gear-driven assembly 2 comprises that power input gear 21, symmetry terminal and that motor 3 is fixedly connected with are located at the gearwheel 22 of power input gear 21 both sides and pinion shaft 23, the power output gear 25 that is meshed with pinion shaft 23 and for the output shaft 26 that is socketed power output gear 25; Power output gear 25 is that key is connected with the Placement of output shaft 26; Described gearwheel 22 and power input gear 21 symmetrical engagements, and gearwheel 22 is that key is connected with the Placement of pinion shaft 23; Be provided with the tapered roller bearing 4 that is socketed on the pinion shaft 23 at pinion shaft 23 two ends; Pinion shaft 23 and power input gear 21 are an involute displacement stub-tooth gear, and power output gear 25 and gearwheel 22 flank profil tops adopt the involute double wedge wide, and the recessed flank profil of transition curve is adopted in the bottom.
In order to adapt to single roller-way transmission and to avoid the high limited situation in center, the axis parallel of pinion shaft 23 and output shaft 26, and the center of pinion shaft 23 height is high in the center of output shaft 26.
The below is described as follows with regard to the working procedure of single electric machines for roller retarder of the present embodiment dotted line transmission: starting electrical machinery 3, namely can drive the power input gear 21 that is fixedly connected with it rotates, because power input gear 21 is meshed with gearwheel 22, gearwheel 22 is fixedly connected with pinion shaft 23 usefulness key Placements, be socketed with tapered roller bearing at pinion shaft 23 two ends, be fixed on the casing 1, therefore namely can drive gearwheel 22 after power input gear 21 rotates rotates, namely can drive pinion shaft 23 after gearwheel 22 rotates rotates, and pinion shaft 23 is meshed with power output gear 25, power output gear 25 can rotate thereupon after pinion shaft 23 rotates, at last, output shaft 26 rotations that connect with key are with it ordered about in power output gear 25 rotations, reach power output.
