Detailed description of the invention
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is specifically described.Should be appreciated that following word only in order to describe one or more concrete embodiments of the present utility model, considered critical is not carried out to the protection domain that the utility model is specifically asked.
The technical scheme that the utility model is taked is as Fig. 1, 2, shown in 3, a kind of device of removal rotating shaft upper bearing (metal), comprise an oil cylinder 11, the cylinder body of oil cylinder 11 is fixed on a cup dolly 16, the piston rod of oil cylinder 11 to be arranged and the end end face of piston rod top and rotating shaft 21 leans along the axis of rotating shaft, the periphery of cup dolly 16 evenly arranges the claw 12 for removing rotating shaft 21 upper bearing (metal) 20 being enclosed in oil cylinder 11 periphery, claw 12 is that a L shape pole is formed, one end of claw 12 is articulated and connected by the first jointed shaft and cup dolly 16, the other end of claw 12 is bent into L shape to the side near oil cylinder 11 piston rod, the piston rod of oil cylinder 11 is provided with a movable loop 14, to having connecting rod 13 near oil cylinder 11 cylinder body side is extended on movable loop 14, connecting rod 13 along the circumference of movable loop 14 evenly arrange and with the corresponding layout of each claw 12, one end of connecting rod 13 consists of the middle part of the second jointed shaft and claw 12 and is articulated and connected, the other end of connecting rod 13 consists of the 3rd jointed shaft and movable loop 14 and is articulated and connected, same group of claw 12, on connecting rod 13 first, two, three jointed shafts are parallel to each other and all perpendicular to piston rod radial arrangement, Compress Spring 15 is provided with between movable loop 14 and oil cylinder 11 cylinder body, Compress Spring 15 is on the piston rod sheathed.The bearing uninstall device of said structure, claw 12 and connecting rod 13 are similar to umbrella frame and arrange, can carry out launching and gathering along with the state of Compress Spring 15, thus are enclosed in the end of claw 12 easily on the end face of bearing 20.During operation, the axle head of the top of piston rod and rotating shaft 21 is leant, regulate Compress Spring 15 that each claw 12 is gathered to pack up, the folding shape end of claw 12 is strained the inner ring of bearing 20, as shown in Figure 4, start oil cylinder 11, piston rod carries out jacking, and claw 12 pulls bearing 20 to move until bearing 20 departs from from rotating shaft 21 completely from rotating shaft 21, realizes the quick removal of bearing 20.Certainly for the bearing 20 of reduced size, it is less that bearing 20 removes required driving force, and it can use cylinder to operate, and requires larger then employing oil cylinder 11 for driving force.
Further scheme is: claw 12 is arranged with ball 121 away from the end, one end of cup dolly 16, the Local Convex of ball 121 is for the end end face of claw 12, so just farthest can avoid the damage of countershaft 21, ensure the installation of new bearing 20, also be conducive to the fast eliminating of bearing 20 simultaneously, reduce the driving force of oil cylinder 11.Claw 12 is preferably provided with 4, is convenient to bearing 20 stress equalization like this, makes bearing 20 removal fast.Bearing 20 can be pounded and drop on connecting rod 13 after removal rotating shaft 21, easily causes connecting rod 13 to damage and bending, the action of each claw 12 cannot be consistent, affect stress equalization when bearing 20 unloads.Therefore, the utility model further scheme is, shaft between piston rod top to movable loop 14 is provided with pin 111, pin 111 is arranged along the circumferential uniform intervals of piston rod, pin 111 suspends the radius holding the spacing of end distance piston rod axis to be greater than rotating shaft 21, and the bar length direction of pin 111 is consistent with the radial direction of piston rod.Stopped by pin 111 pairs of bearings 20, prevent bearing 20 from clashing into connecting rod 13, the bearing 20 after removal drops on pin 111, is also convenient to the taking-up of bearing 20.
In a word, the device of the removal rotating shaft upper bearing (metal) that the utility model provides, bearing can unload from rotating shaft by easily and fast, and can not cause damage by countershaft.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; to know in the utility model after contents; under the prerequisite not departing from the utility model principle; can also make some equal conversion to it and substitute, these convert on an equal basis and substitute and also should be considered as belonging to protection domain of the present utility model.
