Abstract
The utility model relates to a sliding bush device of a diesel engine speed governor, which comprises a sliding bush, and is characterized in that a bearing sleeve is sleeved on the sliding bush, and a thrust bearing is arranged between the bearing sleeve and the sliding bush. An axial hole is opened on the bearing sleeve, and the seat ring of the thrust bearing is installed in the axial hole in the tight fit, and the axial ring of the thrust bearing is installed on the sliding bush in the tight fit. A convex shoulder is arranged on the sliding bush, and is axially pressed with the axial ring of the trust bearing, and an oil hole is arranged on the sliding bush. The sliding bush device changes the original sliding friction into the rolling friction owing to covering the bearing sleeve on the sliding bush and arranging the thrust bearing between the bearing sleeve and the sliding bush, reduces the friction between the relative motion elements on the speed governor as the sliding bush only receives the axial force, and increases the work reliability.
Description
Technical field
The utility model relates to a kind of mechanical speed governor of diesel engine Injection Pump, specifically the sliding bush apparatus of diesel engine speed regulator.
Background technique
The diesel engine that the is used for generator set long-play under the same operating mode of being everlasting, this just requires each component of diesel engine that very high reliability must be arranged.For the mechanical speed governor of diesel injection pump, its component also must have very high reliability.Prior mechanical speed regulator, its structure are that hinged being equipped with flies piece on governor gear, are set with sliding sleeve on the governor gear axle, and the top and the fore-set of sliding sleeve lean.During the governor gear rotation, flying piece opens under action of centrifugal force, the bottom that flies piece promotes to slide on the governor gear axle to slide, and sliding sleeve also rotates around the governor gear axle under the effect of frictional force simultaneously, the relative movement between sliding sleeve and the fore-set so just occurs.The sliding sleeve long-time continuous turns round at same position, and the top of sliding sleeve and be prone to wearing and tearing with the face of the contacted fore-set in top of sliding sleeve directly influences the proper functioning of mechanical speed governor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of sliding bush apparatus of nonabradable diesel engine speed regulator is provided, and this sliding bush apparatus can reduce the friction between the relative movement part on the speed regulator, increases the reliability of work.
Technological scheme according to the utility model provides comprises sliding sleeve, it is characterized in that: be set with bearing housing on the described sliding sleeve, between bearing housing and the described sliding sleeve thrust-bearing be set.
Have axis hole on the described bearing housing, the seat ring drive fit of described thrust-bearing is installed in the described axis hole, and the blowout patche drive fit of described thrust-bearing is installed on the described sliding sleeve.
Described sliding sleeve is provided with convex shoulder, the blowout patche of described convex shoulder and described thrust-bearing axially against.Described sliding sleeve is provided with oilhole.
Compared with the prior art the utility model has the following advantages:
1, the utility model is owing to be set with bearing housing on sliding sleeve, and between bearing housing and sliding sleeve, thrust-bearing is set, thereby original sliding friction is transformed into rolling friction, and sliding sleeve only is subjected to axial force, reduce the friction between the relative movement part on the speed regulator, increased the reliability of work.
2, the convex shoulder that is arranged on the sliding sleeve can play the axially locating effect to thrust-bearing, makes the thrust-bearing location more reliable.
3, sliding sleeve is provided with oilhole, can be used to the gear shaft of lubricated governor gear, has further reduced friction.
Description of drawings
Fig. 1 is the utility model user mode sectional view.
Fig. 2 is a sectional view of the present utility model.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
Figure 1 and Figure 2 comprises extension lever 1, flies piece 2, governor gear 3, bearing housing 4, thrust-bearing 5, sliding sleeve 6, fore-set 7, governor spring 8, oilhole 9 and convex shoulder 10 etc.
As shown in Figure 2, the utility model comprises sliding sleeve 6, is set with bearing housing 4 on the sliding sleeve 6, between bearing housing 4 and the sliding sleeve 6 thrust-bearing 5 is set.Thrust-bearing 5 can adopt thrust ball bearing or thrust roller bearing etc.Sliding sleeve 6 is a cylindrical body, end sealing.
Have axis hole on the bearing housing 4, the seat ring drive fit of thrust-bearing 5 is installed in the described axis hole, and the blowout patche drive fit of thrust-bearing 5 is installed on the sliding sleeve 6.
Sliding sleeve 6 is provided with convex shoulder 10, the blowout patche of convex shoulder 10 and thrust-bearing 5 axially against.10 pairs of thrust-bearings 5 of convex shoulder play the axially locating effect.
Sliding sleeve 6 is provided with oilhole 9.In sliding sleeve 6, add lubricant oil by oilhole 9, be used for lubricating the gear shaft of governor gear 3.
Working procedure of the present utility model is as follows: as shown in Figure 1, speed regulation gear 3 drives and flies piece 2 rotations, flying piece 2 is flown out by centrifugal force, promote sliding sleeve 6 by bearing housing 4 and thrust-bearing 5, sliding sleeve 6 promotes fore-set 7, under the effect that flies piece 2 and governor spring 8, extension lever 1 is made reciprocally swinging, thus the control oil mass.Fly piece 2 when being flown out by centrifugal force, drive bearing housing 4 and rotate, because the effect of thrust-bearing 5, sliding sleeve 6 only is subjected to axial force, thereby only moves axially on the gear shaft of governor gear 3, does not have relative movement between sliding sleeve 6 and the fore-set 7, can not wear and tear.
Claims (4)
1, a kind of sliding bush apparatus of diesel engine speed regulator comprises sliding sleeve (6), it is characterized in that: be set with bearing housing (4) on the described sliding sleeve (6), between bearing housing (4) and the described sliding sleeve (6) thrust-bearing (5) be set.
2, the sliding bush apparatus of diesel engine speed regulator according to claim 1, it is characterized in that having axis hole on the described bearing housing (4), the seat ring drive fit of described thrust-bearing (5) is installed in the described axis hole, and the blowout patche drive fit of described thrust-bearing (5) is installed on the described sliding sleeve (6).
3, the sliding bush apparatus of diesel engine speed regulator according to claim 1 is characterized in that described sliding sleeve (6) is provided with convex shoulder (10), the blowout patche of described convex shoulder (10) and described thrust-bearing (5) axially against.
