Abstract
The invention relates to an improved gearbox drive assembly supporting structure. The improved gearbox drive assembly supporting structure comprises a box body, a high-speed shaft, an intermediate shaft and a low-speed shaft. The high-speed shaft is supported on the box body through a front end sliding bearing and a rear end sliding bearing, the intermediate shaft is supported on the box body through a front end self-aligning roller bearing and a rear end self-aligning roller bearing, the low-speed shaft is supported on the box body through a front end tapered roller bearing and a rear end tapered roller bearing, and a high-speed level large gear and a low-speed level large gear are installed on an input shaft and an output shaft respectively. The sliding bearings are adopted in the high-speed shaft, the roller bearings are adopted in the intermediate shaft and the low-speed shaft, a gearbox is simple in structure, convenient to maintain, low in vibration noise and stable in running, and the problem that the rotating speed span is large is effectively solved. Positioning thrust discs of the sliding bearings are of split structures, and the problem of space interference generated during grinding wheel gear grinding is effectively solved.
Description
Technical field
The present invention relates to gearbox drive technical field, more particularly, to a kind of follow-on gearbox drive assembly supporting knot
Structure.
Background technology
In traditional two-stage parallel axis gear train assembly, high speed shaft selects there is two ways with the bearing of slow-speed shaft：
1. all using rolling bearing, countershaft because of high speed roller bearing and casing requirement on machining accuracy is higher, and in reality processing
Precision is difficult to ensure that, and the vibration of gear-box and noise can be very big；2. all using sliding bearing, although sliding bearing is to processing
The requirement of precision is lower than rolling bearing, but can not form optimal carrying oil film in low-speed running, does not provide enough
Support stiffness, thus it is difficult to meet the running requirements of slow-speed shaft.Therefore, for rotating speed span（High speed shaft and the rotating speed of slow-speed shaft
Difference）Larger gear-box, its bearing type selecting becomes more distinct issues, and the vibration of gear-box and noise are difficult to completely
Foot requires.
Content of the invention
It is an object of the invention to overcoming drawbacks described above, provide one kind can meet simultaneously high speed shaft and slow-speed shaft operating will
Ask, vibrate and the less follow-on gearbox drive component support structure of noise.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that：A kind of follow-on gearbox drive assembly
Supporting structure, including casing 1, high speed shaft 3, jackshaft 5, slow-speed shaft 7, high speed shaft 3 passes through front end sliding bearing 2 and slides in rear end
Bearing 10 is bearing on casing 1, and jackshaft 5 passes through front end self-aligning roller bearing 4 and rear end self-aligning roller bearing 12 is bearing in case
On body 1, slow-speed shaft 7 passes through front end taper roll bearing 6 and rear end taper roll bearing 14 is bearing on casing 1, in input shaft 3
With high speed level gear wheel 11 and slow speed turbine stage gear wheel 13 are respectively mounted on output shaft 7.
Preferably, the positioning thrust disc 9 of rear end sliding bearing 10 be can subdivision symmetrical two halves structure, and with card
Hoop 8 connects fastening.
The high speed shaft of the present invention adopts sliding bearing, jackshaft and slow-speed shaft to adopt rolling bearing, and gear box structure is simple,
Easy to maintenance, vibration noise is low, operates steadily, and efficiently solves the problems, such as that rotating speed span is larger.The positioning thrust of sliding bearing
Disk adopts split-type structural, efficiently solves the problems, such as space interference during emery wheel roll flute.
Brief description
Fig. 1 is the main assembly schematic diagram of the present invention.
Fig. 2 positions the roll flute schematic diagram before thrust disc improves for high speed shaft sliding bearing.
Fig. 3 positions the roll flute schematic diagram after thrust disc improves for high speed shaft sliding bearing.
In figure：1- casing, 2- front end sliding bearing, 3- high speed shaft, 4- front end self-aligning roller bearing, 5- jackshaft, before 6-
End taper roll bearing, 7- slow-speed shaft, 8- clip, 9- positioning thrust disc, 10- rear end sliding bearing, 11- high speed level gear wheel,
12- rear end self-aligning roller bearing, 13- slow speed turbine stage gear wheel, 14- rear end taper roll bearing.
Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is described further.
As shown in figure 1, follow-on gearbox drive component support structure includes casing 1, high speed shaft 3, jackshaft 5, low
Fast axle 7, high speed shaft 3 passes through front end sliding bearing 2 and rear end sliding bearing 10 is bearing on casing 1, and jackshaft 5 is adjusted by front end
Heart roller bearing 4 and rear end self-aligning roller bearing 12 are bearing on casing 1, slow-speed shaft 7 pass through front end taper roll bearing 6 and after
End taper roll bearing 14 is bearing on casing 1, is respectively mounted high speed level gear wheel 11 and low on input shaft 3 and output shaft 7
Fast level gear wheel 13.
Because the rotating speed of high speed shaft is higher, rated speed reaches 30000r/min, when from common rolling bearing it is difficult to
Reach high rotation speed requirements；When from high speed roller bearing, countershaft and casing requirement on machining accuracy very high it is difficult to reach design
Require.Therefore, the two supports assembly of high speed shaft selects the two supports assembly of sliding bearing, jackshaft and slow-speed shaft from rolling
Dynamic bearing.
As shown in Fig. 2 for the gear-box of prior art, using a step surface on high speed shaft 3 as sliding bearing
Positioning thrust disc, because it is nearer away from gear, can interfere with this step surface during emery wheel roll flute, affect roll flute.As Fig. 3 institute
Show, by the positioning thrust disc 9 of the rear end sliding bearing 10 on high speed shaft 3 be changed to can subdivision symmetrical two halves structure, and with clip 8
Connect fastening.Clip can be pulled down with positioning thrust disc when roll flute, efficiently solve the problems, such as the space interference of emery wheel roll flute.
The present invention is not limited to above-mentioned embodiment, the ken possessing in art those of ordinary skill
Interior, can also make a variety of changes on the premise of without departing from present inventive concept and principle.
