Abstract
The utility model relates to a driving device for the rolls of a rolling mill, belonging to the field of the mechanical drive. The utility model comprises a drive motor and two planetary reducers respectively connected with an upper and a lower rolls, wherein, the two planetary reducers adopt the structural form without a base, namely, the inner ring gears of the planetary reducers are simultaneously used as the casings of the planetary reducers, wherein, at least four planetary wheels are provided; thereby, the volumes of the planetary reducers are reduced, the two planetary reducers can be overlapped and arranged up and down together, and the axial dimension and the occupation area of the driving device are reduced.
Description
The utility model belongs to mechanical transmission fields, specifically a kind of transmission device of casting and rolling machine roll.
Two drive transmissions of existing casting and rolling machine roll have adopted two planetary reduction gears to drive upper and lower roll respectively.But what existing this class device all adopted is the common standard planetary reduction gear.Because volume is bigger, its center is farsighted greater than roller radius, so two planetary reduction gears must (as shown in Figure 4) arranged apart vertically, thereby causes the axial dimension of whole transmission device very big, this not only makes its floor space bigger, and overall weight is also bigger.
It is less that task of the present utility model provides a kind of floor space, the transmission device of the casting and rolling machine roll that axial dimension is less.
Task of the present utility model is to finish as follows: the transmission device of the casting and rolling machine roll that is provided comprises the planetary reduction gear that drive motors and two link with upper and lower roll respectively, the ring gear that improvements of the present utility model are said two planetary reduction gears is again simultaneously as the housing of planetary reduction gear, planetary gear has four at least, and two above-mentioned planetary reduction gear upper-lower overlappings are installed together.Because planetary reduction gear has adopted with the version of ring gear as housing, increased the quantity of planetary gear simultaneously again, so the volume of whole planetary reduction gear is less, thereby can realize the upper-lower overlapping installation, the axial dimension of transmission device is reduced greatly.
Compared with prior art, structure of the present utility model is compact, and overall weight alleviates, and cost is lower.
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
Fig. 1 is the overall structure figure of an embodiment of the utility model.
Fig. 2 is the overall structure figure of another embodiment of the utility model.
Fig. 3 is the structure chart of planetary reduction gear ring gear among Fig. 1, Fig. 2.
Fig. 4 is a kind of transmission structures figure of existing casting and rolling machine roll.Numbering wherein: 21-motor, 22-planetary reduction gear, 23, the 24-universal-joint spindle, 25-roll.
As shown in Figure 1: the roll transmission device is two drive forms, and promptly drive motors 1 has two, and they link with two planetary reduction gears 2,3 respectively, and two planetary reduction gears, 2,3 upper-lower overlappings are placed and are separately fixed on the side plate of support 4.The output shaft of two planetary reduction gears links by universal-joint spindle 5 and roll 6 again.
As shown in Figure 2: the roll transmission device is single drive form, promptly has only a drive motors 7, is provided with a gear distribution box 10 with two with rotating speed output shaft between this drive motors and two planetary reduction gears 8,9.That is, by gear distribution box 10 shuntings, give roll 12 by two planetary reduction gears 8,9, universal-joint spindle 11 with transmission of power more earlier.
The structure of the planetary reduction gear of above-mentioned two examples is identical, all adopts no understructure form, that is, ring gear 13 is simultaneously again as the housing of decelerator, and respectively there is an extension 14 its both sides, are circumferentially with the hole 15 of a plurality of connection usefulness, and its structure as shown in Figure 3.
Claims (3)
1, a kind of transmission device of casting and rolling machine roll, comprise the planetary reduction gear (2,3,8,9) that drive motors (1,7) and two link with upper and lower roll respectively, the ring gear (13) that it is characterized in that said two planetary reduction gears (2,3,8,9) is again simultaneously as the housing of planetary reduction gear, planetary gear has four at least, and two above-mentioned planetary reduction gears (2,3,8,9) upper-lower overlapping is installed together.
2, the transmission device of casting and rolling machine roll as claimed in claim 1 is characterized in that drive motors (1) has two, and they link with above-mentioned two planetary reduction gears (2,3) respectively.
3, the transmission device of casting and rolling machine roll as claimed in claim 1 is characterized in that drive motors (1) has one, is provided with one between this drive motors and above-mentioned two planetary reduction gears (8,9) and has two gear distribution boxs with rotating speed output shaft (10).
