The input axle is installed on the parallel axle gearbox through the bearing, the input axle gear which is arranged on the input axle is combined with the middle gear axle, the middle large gear is installed on the middle gear axle, and is combined with the output axle gear. The input axle, the middle gear axle and the output gear axle are installed on the body of the parallel axle gearbox through the bearing. The utility model uses two-stage gear transmission, thereby the rotational speed and the speed ratio of the parallel axle gearbox are increased.
Description
Technical field
The utility model relates to the mechanical speed change manufacturing field of equipment, more particularly, relates to a kind of parallel-axes gears case.
Background technique
At present, speed ratio commonly used is 13 to the maximum, and is high-speed gear box 25 or more for speed ratio, because output speed height, gear engagement degree height and bearing shaft footpath linear velocity height, the reasons such as poor stability of axle system, one-level parallel axes high-speed gear box commonly used is difficult to realization.
The model utility content
In view of this, the utility model provides a kind of parallel-axes gears case, improves the requirement of speed ratio to realize the parallel-axes gears case under situation at a high speed.
For achieving the above object, the utility model provides following technological scheme:
A kind of parallel-axes gears case, the transmission system of described parallel-axes gears case is the two poles of the earth gear transmission, the transmission system of described parallel-axes gears case comprises: input shaft, input shaft gear, intermediate gear shaft, gear broad in the middle, output gear shaft and bearing, described input shaft by Bearing Installation on described parallel-axes gears case, the input shaft gear that is arranged on the described input shaft matches with described intermediate gear shaft, described gear broad in the middle is installed on the described intermediate gear shaft, and match described input shaft with described output shaft gear, intermediate gear shaft and output gear shaft by Bearing Installation on the casing of described parallel-axes gears case.
Preferably, in the above-mentioned parallel-axes gears case, described bearing is a tilting-pad bearing.
Technique scheme has following beneficial effect:
Parallel-axes gears case provided by the utility model adopts the two-stage parallel axis speedup, earlier with the speed increase to a certain degree, to desired speed ratio, has improved output speed in second level speedup, has improved the speed ratio of whole parallel-axes gears case.
In addition, the parallel-axes gears case that the utility model provides adopts tilting-pad bearing, and it is short to support span, good rigidly, the stability when having improved parallel-axes gears case high speed rotating.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment discloses a kind of parallel-axes gears case, shown in attached Fig. 1 and 2, to improve the speed ratio of parallel-axes gears case.
A kind of parallel-axes gears case, the transmission system of described parallel-axes gears case is the two poles of the earth gear transmission, the transmission system of described parallel-axes gears case comprises: input shaft 1, input shaft gear 2, intermediate gear shaft 6, gear 10 broad in the middle, output gear shaft 14 and tilting-pad bearing 3,5,13, described input shaft 1 is installed on the described parallel-axes gears case by tilting-pad bearing 3, the input shaft gear 2 that is arranged on the described input shaft 1 matches with described intermediate gear shaft 6, gear 10 broad in the middle is installed on the described intermediate gear shaft 6, and match described input shaft with described output shaft gear 14, intermediate gear shaft and output gear shaft by Bearing Installation on the lower box 16 and upper box 17 of described parallel-axes gears case.End cap 4, oil separator 11 and output end cover 12 are installed on the lower box, and lock washer 7, round nut 8 and thrust disc 9 are installed in a side of intermediate gear shaft 6.
The utility model adopts the two-stage transmission to reach the needed speed ratio of parallel-axes gears case.It is to adopt the stability watt support of can inclining preferably, and it is short to support span, and good rigidly by adjusting the bearing film gap, increasing the rigidity of output gear shaft, makes the stability of axle system be improved.
For the control of gear meshing noise and engagement stationarity is that tip relief by increasing gear engagement contact ratio, gear and correction of the flank shape are handled and realized.
In operation process, gear 10 broad in the middle and output gear shaft 14 engagement level gear linear velocity and gear surface temperature height adopt engaging-in and nibble out oil jet lubrication simultaneously, make that the flank of tooth is lubricated, cooling is abundant at the parallel teeth roller box.Strengthen the latus rectum of back leakage connection 15 simultaneously, increased the gear-box recirculating oil quantity, the phenomenon that has prevented to stir heating of oil.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
