Description
Technical field
The utility model relates to a kind of high-speed rod gearbox.
Background technology
Being continually changing of steel industry now, metallurgical Steel-rolling Industry has entered into urgent need and has improved equipment and technology level, saving
The management phase that cost is increased the benefit, it is also proposed new requirement for production equipment.Production needs according to user, promote
The design of Novel dual frame reducing-sizing mill equipment, to reach to improve mill milling speed, improves the purpose of production efficiency.
With the shaping of Stand Mill reducing-sizing mill equipment theory, its high-revolving need of work just promotes the defeated of gearbox
Go out speed to improve, as only changed former gearbox form, then need the motor that installation power is bigger, improve turning of motor
Dynamic speed, thus greatly adds the cost fund that Novel dual frame reducing-sizing mill equipment is gone into operation.
Content of the invention
For disadvantages mentioned above, the utility model provides a kind of high-speed rod gearbox.
The purpose of this utility model is achieved through the following technical solutions:
A kind of high-speed rod gearbox, is made up of base, lower box, case lid, two gear shaft unit, each gear shaft list
Unit includes cylinder roller bearing, injection loop, gear shaft, deep groove ball bearing, cushion and labyrinth type bearing protector, and its feature exists
In: cylinder roller bearing, deep groove ball bearing and labyrinth type bearing protector are installed successively in gear shaft one end, deep groove ball bearing
Both sides are provided with cushion, are provided with injection loop between cylinder roller bearing and deep groove ball bearing, and the other end of gear shaft is installed
Cylinder roller bearing, lower box is installed on base and is secured to connect, installing two the gear shaft unit assembling
In lower box, mould assembling lid.
The beneficial effects of the utility model: the utility model is reasonable in design, meet equipment and use needs, and can accomplishing property
Can stablize, reduce cost, requirement easy to maintenance.Shaft strength impact is alleviated in cushion design；Increase injection loop, use oil spout
Formula lubrication strengthens lubricant effect；Use bearing protector, strengthen oil sealing effect, play functions of waterproof and dustproof to bearing, protect work
Make bearing, extend bearing service life.
Brief description
Fig. 1 is the utility model outside drawing.
Fig. 2 is the utility model drive mechanism figure.
Detailed description of the invention
The utility model is described in further detail in citing below in conjunction with the accompanying drawings:
Embodiment 1
As shown in Figure 1-2: a kind of high-speed rod gearbox, by base the 1st, lower box the 2nd, case lid the 3rd, two gear shaft unit groups
Becoming, each gear shaft unit includes cylinder roller bearing the 4th, injection loop the 5th, gear shaft the 6th, deep groove ball bearing the 7th, cushion 8 and labyrinth
Formula bearing protector 9, it is characterised in that: cylinder roller bearing the 4th, deep groove ball bearing 7 and labyrinth are installed successively in gear shaft 6 one end
Formula bearing protector 9, the both sides of deep groove ball bearing 7 are provided with cushion 8, pacify between cylinder roller bearing 4 and deep groove ball bearing 7
Equipped with injection loop 5, the other end of gear shaft 6 installs cylinder roller bearing 4, and lower box 2 is installed on base 1 and is secured to
Connect, be installed on assemble two gear shaft unit in lower box 2, mould assembling lid 3.
During work, deep groove ball bearing is by axial force, owing to increasing cushion 8 in deep groove ball bearing 7 both sides, thus alleviates
Receiving axial impact during equipment operation, between centers installs injection loop 5, is evenly equipped with nozzle opening, i.e. to axle in this injection loop
Hold employing oil injection type lubrication, while substantially increasing lubricant effect, reduce temperature during bearing operation；Axle head uses labyrinth
Formula bearing protector 9, this parts have a preferable oil sealing effect, and use non-contacting seal with between centers, prevent water and
Dust enters box house and plays a very good protection bearing operation.
