Embodiment
The present invention core be to provide a kind of flywheel terminal pad boom hoisting, spline is not damaged during lifting.
In order that those skilled in the art more fully understands technical scheme, below in conjunction with accompanying drawing and specifically
Embodiment, to the present invention flywheel terminal pad boom hoisting explanation is described in detail.
As shown in figure 3, it is a kind of structure chart of specific embodiment of flywheel terminal pad boom hoisting provided by the invention；The dress
The suspension hook 1 set including bending is put, the top of suspension hook 1 sets suspension ring 11, and bottom laterally sets lifting boom 12, suspension ring 11 and lifting
Connected between bar 12 by support bar 13, suspension ring 11 are used to connect lifting appliance during use, and lifting boom 12 is used to be inserted into spline
In groove, support bar 13 is used to bear moment of flexure caused by the weight of flywheel terminal pad.In the end of lifting boom 12, spline 2 is set,
When lifting boom 12 stretches into spline, spline 2 can coordinate with the spline of flywheel terminal pad to be clamped, the outer surface of spline and flower
The surface of internal cavity fitting of keyway, has a bigger contact area, in hoisting process spline to the pressure of spline surface of internal cavity compared with
Small, pressure is evenly distributed everywhere, and the damage to spline inner wall surface is smaller, can dramatically reduce suffered by spline
Abrasion, ensure spline being capable of long-term normal use.
On the basis of such scheme, the present invention provides a kind of more preferred technical scheme, as shown in figure 4, in Fig. 3
The partial enlarged drawing of X section；Bearing 3 is set respectively at the inner chamber both ends of spline 2, and the inner ring of bearing 3 is stuck on lifting boom 12, axle
3 outer ring is held to be stuck on the inner chamber of spline 2.The inner ring of bearing 3 keeps fixing with lifting boom 12, and outer ring keeps fixing with spline 2.
, it is necessary to be bolted with the flywheel of engine by ring flange after flywheel terminal pad is lifted into appropriate position, in order to
Bolt hole is aligned, it is necessary to which flywheel terminal pad is rotated a certain angle, the weight of its own is larger, then can be light by bearing 3
Loose ground rotary flywheel terminal pad, facilitates bolt hole to align connection.
In order to realize the spacing of bearing 3, it is set not slide axially, the present invention provides a kind of preferred scheme herein,
As shown in Figure 5A, it is the sectional structure chart of spline 2, an orifice ring is set respectively in position of the inner chamber of spline 2 on the outside of both ends
Groove 21, spline is located at the position at both ends respectively as a passage, two position orifice ring grooves 21.Place and use in position orifice ring groove 21
Location hole card spring 4 in the outer ring of Limit Bearing 3, location hole card spring 4 is inwardly projecting in position orifice ring groove 21 after installing, and can withstand on bearing 3
In the side wall of outer ring, prevent bearing 3 from sliding axially.Similarly, set on lifting boom 12 corresponding with position orifice ring groove 21
Axle annular groove 121, it is the structure chart of suspension hook 1 as shown in Figure 5 B, axle annular groove 121 aligns with the location of position orifice ring groove 21,
Two axles are outwardly in lifting boom 12 with jump ring 5 with the axle jump ring 5 placed in annular groove 121 for the inner ring of Limit Bearing 3, axle
Outer surface, can be contacted with the side wall of the inner ring of bearing 3, so as to which the inner ring of bearing 3 is carried out into axial limiting.Except above-mentioned spacing
Outside mode, bearing 3 can also be fixed by modes such as welding, but bearing 3 is consumable accessory, using location hole card spring 4 and axle card
Bearing can be carried out independent dismounting and change, escapable cost by the spacing mode of spring 5.
In order to improve anti-bending strength, reinforcement 14, reinforcement 14, lifting boom are set between lifting boom 12 and support bar 13
12 and support bar 13 it is triangle.Moment of flexure caused by lifting boom 12 can stretch to reinforcement 14, the tensile capacity of rod member
It is higher, therefore overall bending resistance can be improved.Reinforcement 14, lifting boom 12 and the three of support bar 13 are disposed as in the present invention
