Abstract
The utility model relates to the design technical field of a roll grinder lathe head transmission shaft supporting mechanism, in particular to a roll grinder lathe head transmission shaft assistant supporting mechanism. The supporting mechanism comprises a lathe head (12). A transmission shaft (3) is arranged on the lathe head (12) by an eccentric sleeve (1). The utility model is characterized in that the shaft head of the transmission shaft (3) is arranged in an eccentric disc (6) by a self-aligning bearing (7); the eccentric disc (6) is arranged on the lathe head (12) by a bolt (9); a first belt pulley (5) is arranged on the transmission shaft (3) by a key (4); the belt pulley (5) is connected with a second belt pulley (11) by a belt (10); the second belt pulley (11) is arranged on a shaft (13) by the bearing; and a drive plate (14) is fixedly arranged on the second belt pulley (11) by the bolt. The utility model reduces the bending of the transmission shaft, increases the rigidity of the shaft, avoids the sudden disabled probability of the transmission shaft and ensures the design service life of the shaft.
Description
Technical field
The utility model technology relates to roll grinder cardan-shaft suspension mechanism design technical field, relates in particular to a kind of roll grinder headstock power transmission shaft aiding support mechanism.
Background technology
At present, because the roll grinder power transmission shaft is an eccentric stiffener, therefore spindle drive one end all is the structure that overhangs, like this, when power transmission shaft transmits moment of torsion toward main shaft, owing to interact, bigger bending can take place in the power transmission shaft projecting end, this singly can not influence the transmission moment of torsion, and the life-span of power transmission shaft at projecting end fulcrum place had a significant impact, even the catastrophic failure fracture takes place at the fulcrum place power transmission shaft.
The utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art that a kind of roll grinder headstock power transmission shaft aiding support mechanism is provided, reduced the bending of power transmission shaft, increase the rigidity of axle, avoided the possibility of power transmission shaft generation catastrophic failure, guaranteed the design service life of axle.
For achieving the above object, the technical scheme that the utility model is taked is: described roll grinder headstock power transmission shaft aiding support mechanism, include the headstock (12), power transmission shaft (3) is arranged on the headstock (12) by eccentric bushing (1), its characteristics are: the spindle nose of power transmission shaft (3) is located in the eccentric disc (6) by self-aligning bearing bearing (7), eccentric disc (6) is installed on the headstock (12) by screw (9), first belt pulley (5) is located on the power transmission shaft (3) by key (4), belt pulley (5) links to each other with second belt pulley (11) by belt (10), second belt pulley (11) is located on the axle (13) by bearing, and dial (14) is fixedly mounted on second belt pulley (11) by screw.
Described power transmission shaft (3) is gone up and also is provided with turn (8) in the outside of self-aligning bearing bearing (7).Be provided with spring bearing (2) between eccentric bushing (1) and the power transmission shaft (3).
The beneficial effects of the utility model, the end increases an aiding support mechanism overhanging, make power transmission shaft when flexural deformation, aiding support mechanism can make it become the two supports form by the form of overhanging, thereby reduce the bending of power transmission shaft, increase the rigidity of axle, avoided the possibility of power transmission shaft generation catastrophic failure, guaranteed the design service life of axle.
Description of drawings
Fig. 1 is the utility model structural principle schematic diagram.
The specific embodiment
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
Embodiment 1, see Fig. 1, described roll grinder headstock power transmission shaft aiding support mechanism, include the headstock 12, power transmission shaft 3 is arranged on the headstock 12 by eccentric bushing 1, its characteristics are: the spindle nose of power transmission shaft 3 is located in the eccentric disc 6 by self-aligning bearing bearing 7, eccentric disc 6 is installed on the headstock 12 by screw 9, first belt pulley 5 is located on the power transmission shaft 3 by key 4, belt pulley 5 links to each other with second belt pulley 11 by belt 10, second belt pulley 11 is located on the axle 13 by bearing, and dial 14 is fixedly mounted on second belt pulley 11 by screw.
The outside at self-aligning bearing bearing 7 on the described power transmission shaft 3 also is provided with turn 8.Be provided with spring bearing 2 between eccentric bushing 1 and the power transmission shaft 3.
During transmission, power passes to second belt pulley, 11, the second belt pulleys 11 by first belt pulley 5 on the power transmission shaft 3 through belt 10 and drives dial 14 rotations.
Claims (3)
