Abstract
The utility model relates to a shaft, in particular to a rough rolling and vertical rolling speed reducer gear box output driving shaft. The rough rolling and vertical rolling speed reducer gear box output driving shaft comprises a shaft body, a bearing and a gear, wherein, the bearing and the gear are arranged on the shaft body. A thrust self-aligning roller bearing is arranged on the fixed end of the shaft body. Due to the fact that the thrust self-aligning roller bearing is additionally arranged at the upper side of the fixed end of the rough rolling and vertical rolling speed reducer gear box output driving shaft, all axial force of the driving shaft is borne through the bearing, service lift of fixed bearings at two ends of the shaft is prolonged, replacement frequency of a speed reducer is reduced, standby part loss is reduced, operation rate and production efficiency of a rolling mill are improved and production cost is decreased.
Description
Technical field
The utility model relates to a kind of axle, relates in particular to a kind of roughing rolling on edge reducer gear case output driving shaft.
Background technology
Present most of Metallurgical Enterprise roughing rolling on edge reducer gear case output driving shaft does not design axial carrying device, only rely on single all axial forces of stiff end loading ability of bearing of axle (as shown in Figure 1), this driving shaft can the regular stiff end bearing holding capacity that occurs excessively cause damage, reductor reduces service life, increase replacement frequency, reduce production efficiency, improve production cost.
The utility model content
Defective and deficiency that the utility model exists in order to solve above-mentioned prior art provide a kind of roughing rolling on edge reducer gear case output driving shaft that can reduce replacing speed reducer frequency, the consumption of minimizing spare unit, raising milling train running rate and production efficiency, reduce production costs.
The technical solution of the utility model: a kind of roughing rolling on edge reducer gear case output driving shaft comprises axis body, is arranged on bearing and gear on axis body, installed thrust self-aligning roller bearing on described axis body stiff end.
Preferably, described bearing comprises clutch shaft bearing and the second bearing, and described gear comprises the first gear and the second gear between clutch shaft bearing and the second bearing.
Preferably, described self-aligning thrust roller bearing is plane bearing.
Preferably, described self-aligning thrust roller bearing is arranged on axis body by screw.
The utility model installs self-aligning thrust roller bearing additional above roughing rolling on edge reducer gear case output driving shaft stiff end, bear all axial forces of driving shaft by this bearing, thereby extending shaft two ends rigid bearing service life, reduced the replacing speed reducer frequency, reduced spare unit consumption, improved milling train running rate and production efficiency, reduced production cost.
Description of drawings
Fig. 1 is the structural representation of roughing rolling on edge reducer gear case output driving shaft in prior art;
Fig. 2 is structural representation of the present utility model.
Fig. 1. the first gear, 2. clutch shaft bearing, 3. the second gear, 4. the second bearing, 5. self-aligning thrust roller bearing, 6. axis body, 7. screw.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but is not restriction to the utility model protection domain.
As shown in Figure 2, a kind of roughing rolling on edge reducer gear case output driving shaft comprises axis body 6, is arranged on axis body 6 bearing and gear, installed thrust self-aligning roller bearing 5 on axis body 6 stiff ends.Bearing comprises clutch shaft bearing 2 and the second bearing 4, states gear and comprises the first gear 1 and the second gear 3 between clutch shaft bearing 2 and the second bearing 4.Self-aligning thrust roller bearing 5 is plane bearing.Self-aligning thrust roller bearing 5 is arranged on axis body 1 by screw 7.
The utility model installs self-aligning thrust roller bearing additional above roughing rolling on edge reducer gear case output driving shaft stiff end, bear all axial forces of driving shaft by this bearing, thereby extending shaft two ends rigid bearing service life, reduced the replacing speed reducer frequency, reduced spare unit consumption, improved milling train running rate and production efficiency, reduced production cost.
