Specific embodiment
Embodiment
A kind of detachable bearing body being applied on dual-gripper pump as shown in Figure 2 of the present embodiment, is installed on such as Fig. 1 institute On the end cap of the driven end bearing body 1 of the dual-gripper pump shown, small bearing 21 is installed in the middle part of the end cap of driven end bearing body 1, Small axis 14 is worn on small bearing 21, gear wheel 19 is arranged on small axis 14, passes through retainingf key 17 between small axis 14 and gear wheel 19 It is affixed and fixed in the end face locked spacer of gear wheel 19 and fixture nut 15.Four screw threads are attacked on driven end bearing body 1 Hole, the position of threaded hole are equipped with holding screw 20, holding screw 20 and threaded hole on threaded hole about small 14 central symmetry of axis Screw thread it is identical, pinion gear 18 is installed on holding screw 20, between each other using interference fit, holding screw 20 front end top On 3 outer ring of bearing of 1 inside of driven end bearing body, the length of each holding screw 20 is identical.Gear wheel 19 and 18 phase of pinion gear Mutually cooperation.Rotational handle 13 is installed on gear wheel 19.Gear wheel 19 and the transmission ratio of pinion gear 18 can be in 1:16~1:20 Between selection one suitable ratio be configured.19 radius of gear wheel is 4-6 times of 18 radius of pinion gear.The center of threaded hole The centerline parallel of line and small axis 14.Holding screw 20 is fine thread, and the screw pitch of fine thread and the radius of gear wheel 19 are matched It closes, when gear wheel 19 rotates a circle, driven end bearing body 1 can be made to separate with 3 outer ring of bearing by holding screw 20, canine tooth The facewidth of wheel 19 is greater than 3 thickness of bearing.
In actual use, driven end bearing body 1 and drive end bearing body 11 are fixed by bearing body pressure ring 2 and the pump housing 9, Axial force radial force caused by the weight and operating of entire rotor part 12 is transmitted to 1 He of driven end bearing body by bearing 3 On drive end bearing body 11, it is transmitted on the pump housing 9 by driven end bearing body 1 and drive end bearing body 11.
It is all vulnerable part, the component that need to often replace has bearing 3, bearing rib when pumping upper entire rotor part 12 operating Circle 10, machine seal axle sleeve 6, mechanical seal 5, impeller 8, sealing ring 7, and these components with change require disassembly driven end bearing body 1。
Therefore small axis 14 is worn on small parts of bearings 1, greatly by installing one small bearing 21 on driven end bearing body 1 Gear 19 and small axis 14 are connected with retainingf key 17, axial locked with locked spacer 16 and nut 15.Again on driven end bearing body 1 4 threaded holes are attacked, 4 holding screws 20 are installed on threaded hole, the outer ring of bearing 3 is just withstood on when holding screw 20 is screwed into, Pinion gear 18 is installed on holding screw 20.Rotational handle 13 is installed on gear wheel 19.When firmly rotational handle 13, drive big Gear 19 rotates, and gear wheel 19 drives 4 pinion gears 18 to rotate again, and 4 pinion gears 18 drive 4 holding screws 20 to be screwed into, and pushes up Behind 3 outer ring of bearing, reversely driven end bearing body 1 will be ejected.
Specific installation process is as follows, first retainingf key 17 is mounted on small axis 14, then small bearing 21 is installed on small axis 14, Using heating assembly when small bearing 21 is installed;It is mounted on bearing body by the small axis 14 for installing small bearing 21, small bearing 21 Outer ring and bearing body cooperation are using interference fit;Pinion gear 18 is mounted on holding screw 20, using interference fit;By bearing Screw thread identical with holding screw is attacked on body, and holding screw band pinion gear is screwed into bearing body threaded hole, and is matched with gear wheel It closes;Gear wheel 19 is mounted on small axis 14, end face locked spacer 16 and fixture nut 15 are fixed, will turn after being installed Fixed handle 13 is mounted on gear wheel 19;Rotor part 12 is installed, starts that driven end bearing body 1 is installed after bearings at both ends locking With drive end bearing body 11, the jackscrew screw of driven end bearing body is regulated, bearing body is tapped down on bearing top circle, then is pacified Bearing gland 4 is filled, bearing gland 4 is fixed by bolts on bearing body;By rotor part 12, drive end bearing body 11, driven End bearing body 1, bearing gland 4, sealing ring 7 be lifted on the pump housing 9;To entirely it be turned after being installed with bearing body pressure ring 2 Subassembly 12, drive end bearing body 11, driven end bearing body 1, bearing gland 4 are fixed on the pump housing 9.
When being dismantled, 4 pinion gear rotations are driven with gear wheel, 4 pinion gears drive 4 holding screws to act on axis Bearing outer-ring, it is bearing thickness that holding screw, which is screwed into depth, and bearing body is ejected bearing outer ring by the power rotated by direction, this process 4 A screw uniform force, convenient disassembly not only shorten the pump repair time, but also improve the reliability of pump installation maintenance.
The utility model is not limited to the above embodiment.All technical solutions formed using equivalent replacement, all fall within this reality With the protection scope of novel requirement.
