Embodiment
Below in conjunction with accompanying drawing, further illustrate specific embodiments of the invention.
The present invention discloses a kind of tune oil axle assembly being applicable to large-sized low-speed diesel engine peculiar to vessel, and this diesel engine adjusts oily axle assembly to comprise plug 1, is set in the inner rocker arm 2 on plug 1, and the torque spring 4 be set in successively on inner rocker arm 2 and outer rocker arm 3.
As shown in Figure 1, plug 1 comprises the first portion 11 and second portion 12 that axially connect, and wherein the radius of first portion 11 is slightly larger than the radius of second portion.
As shown in Figure 2, adjust the sectional view of the inner rocker arm 2 of oily axle assembly for diesel engine, inner rocker arm 2 comprises inner rocker arm sleeve 21 and is fixed on the inner rocker arm bar 22 on inner rocker arm sleeve 21.On the internal diameter of inner rocker arm sleeve 21 and plug 1, the external diameter of second portion 12 is suitable, but is less than the external diameter of plug 1 first portion 11.Inner rocker arm 2 is set on plug 1 on second portion 12 by inner rocker arm sleeve 21, and due to second portion 12 poor with the external diameter of first portion 11, can stop that inner rocker arm 2 moves to the first portion 11 of plug 1.
As shown in Figure 3, adjust the sectional view of the outer rocker arm 3 of oily axle assembly for diesel engine, outer rocker arm 3 comprises outer rocker arm sleeve 31 and is fixed on the outer rocker arm bar 32 on outer rocker arm sleeve 31.
As Fig. 3 and shown in composition graphs 2, inner rocker arm sleeve 21 outer edge surface is provided with circular groove 23, on the internal diameter of outer rocker arm sleeve 31 and inner rocker arm sleeve 21, the external diameter of circular groove 23 matches, but the internal diameter of outer rocker arm sleeve 31 is less than the external diameter of inner rocker arm sleeve 21 remaining part outer ring.The outer rocker arm sleeve 31 of outer rocker arm 3 can be set on the circular groove 23 of inner rocker arm sleeve 21.
Torque spring 4 is arranged between inner rocker arm 2 and outer rocker arm 3, and the two ends of torque spring 4 connect inner rocker arm 2 and outer rocker arm 3 respectively, and are set on inner rocker arm sleeve 21.
As shown in Figure 4, the present invention discloses the manufacture method that oily axle assembly adjusted by a kind of diesel engine, and this manufacture method comprises following steps:
Step 1, as shown in Figure 5, plug 1 horizontal positioned, is fixed in bench vice 5 by the first portion 11 of plug 1, and the inner rocker arm sleeve 21 of inner rocker arm 2 is sealed in plug 1 by the outer end of plug 1 second portion 12, and is set on this second portion 12.Because the internal diameter of inner rocker arm sleeve 21 and the external diameter of second portion 12 match, and be less than the external diameter of first portion 11, second portion 12 limits the movement of inner rocker arm sleeve 21 with the external diameter difference of first portion 11, makes inner rocker arm 2 be arranged on joint with first portion 11 on second portion 12.
Step 2, as shown in Figure 6, torque spring 4 is sealed in plug 1 by second portion 12 outer end, is set on inner rocker arm sleeve 21, and one end of torque spring 4 and inner rocker arm 2 buckle are fixed.
Step 3, as shown in Figure 7, the outer rocker arm sleeve 31 of outer rocker arm 3 seals in plug 1 by second portion 12 outer end, is located between outer rocker arm 3 and inner rocker arm 2 by torque spring 4.Then torque spring 4 is extended elongation, one end buckle of torque spring 4 in contrast to inner rocker arm 2 is fixed on outer rocker arm 3.
Step 4, as shown in Figure 8, inner rocker arm sleeve 21 is provided with circular groove 23 towards one end of second portion 12 outer end.On the internal diameter of outer rocker arm sleeve 31 and inner rocker arm sleeve 21, the external diameter of circular groove 23 matches, and is less than the external diameter of inner rocker arm sleeve 21.So the outer rocker arm sleeve 31 of outer rocker arm 3 is set on the circular groove 23 of inner rocker arm sleeve 21.Outer rocker arm 3 and inner rocker arm 2 agree with fixing, complete assembling manufacturing.
Although content of the present invention has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple amendment of the present invention and substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
