Description
Technical field
Diesel Engine Mechanical manufacturing technology field is the utility model is related to, specifically a kind of installation of crankshaft of diesel engine damper
Positioning instrument.
Background technology
Wide variety of medal spring chip damper can efficiently reduce crankshaft vibrations, damper in Diesel Crankshaft System
There is oil pipe to be connected with the lubricating oil system of diesel engine, when diesel engine operates, remaining space often fills up lubricating oil in damper, and one
The Relative friction that aspect is leaned between multilayer wind spring produces damping, and more important is when lubricating oil is pressed towards opposite side from wind spring side
Caused fluid friction damping so that vibrational energy caused by crankshaft system is as much as possible to be absorbed by damper, so as to subtract
Lack the vibration of bent axle, improve the service life of bent axle, while lubricating oil can also lubricate wind spring rubbing surface and take away heat.
The position orientation problem of crankshaft vibration damper, this position can be all related in the production of diesel engine and maintenance process
Determine to obtain the bad behavior in service that will directly influence bent axle, or even damage engine crankshaft and damper, influence diesel engine just
Often work.The installation of general damper is to be carried out by being positioned manually with the thrust of hydraulic elongator.Crankshaft center, bent axle pin-and-hole
With pin-and-hole sight alignment in damper driving wheel, it just can ensure that damper is accurately installed.It is big that error is positioned manually by lifting, if
It is inaccurate, it is necessary to rotate bulky equipment, waste time and energy.Therefore reasonably accurate determine that the position of damper is particularly significant.
In the production process of diesel engine, directly positioned and fixed when installing crankshaft vibration damper using instrument, it is and artificial
Positioning is compared, and the former can save substantial amounts of man-hour, and this process more advantages of simple.And damper and hydraulic elongator sheet
Body is heavy, it is not easy to operates.
To sum up, needed during the production maintenance of diesel engine a kind of simple in construction, easy to operate while also more light
Damper positioning instrument.
Utility model content
The purpose of this utility model provides a kind of installation positioning instrument of crankshaft of diesel engine damper, overcomes actual production
The fixed inconvenience of damper positioning, makes actual production meet technological requirement in journey, and easy to operation.
The technical solution of the utility model is as follows：
A kind of installation positioning instrument of crankshaft of diesel engine damper, its feature are, by ring part and trapezoidal portion one
Into being provided with the first dowel hole on described ring part, the second dowel hole be provided with described trapezoidal portion, for alignment pin
Insertion.
The outer surface of described ring part is engaged with the projection of bent axle on diesel engine stand.
The first described dowel hole is the dowel holes of φ 15 that depth is 20mm, and the second described dowel hole is depth
For 55mm φ 22 dowel hole.
The first described dowel hole and the depth difference of the second dowel hole are 35mm.
Described ring part is that internal diameter is φ 100, external diameter φ 179 cylinder.
The utility model is obtained by cast blank through over mechanical processing, and its material can be stainless steel or can cast aluminium.
Compared with prior art, the beneficial effects of the utility model are：
1) simple in construction, component is few, easy to process.
2) it is easily operated, accurate positioning, save man-hour.
Brief description of the drawings
Fig. 1 is the structural representation of the installation positioning instrument of the utility model crankshaft of diesel engine damper
Fig. 2 is the sectional view of the installation positioning instrument of the utility model crankshaft of diesel engine damper
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Please referring initially to Fig. 1, Fig. 1 is the structural representation of the installation positioning instrument of the utility model crankshaft of diesel engine damper
Figure, as illustrated, a kind of installation positioning instrument of crankshaft of diesel engine damper is integrally formed by ring part and trapezoidal portion, described
Ring part be provided with the first dowel hole 1, the second dowel hole 2 is provided with described trapezoidal portion, for alignment pin insert.Institute
The first dowel hole stated is the dowel holes of φ 15 that depth is 20mm, and the second described dowel hole is the φ that depth is 55mm
22 dowel hole.The first described dowel hole and the depth difference of the second dowel hole are 35mm, more than damper end with
Requirement distance 21mm~25mm of timing gears case end, it is ensured that positioning smoothly positioning and the smooth installation of damper.
Described ring part is internal diameter for φ 100, external diameter φ 179 cylinder, its outer surface with it is bent on diesel engine stand
The projection of axle is engaged, and device is overlapped with crankshaft center line.
φ 22 pin-and-hole is used to insert corresponding a diameter of φ 22, overall length 90mm alignment pin, small φ 15 pin-and-hole insertion
A diameter of φ 15, overall length are 95mmd alignment pins.
Damper is lifted by crane to crankshaft timing gear end, is pushed into the bent axle conical surface by hand.The design instrument is installed to frame song
The high spot of axle, notice that two pin-and-holes of instrument should be corresponding respectively with damper driving wheel pin-and-hole and bent axle pin-and-hole, load onto correspondingly
The positioning finger setting of size.Next damper can is fixedly mounted according to positioning the step of crankshaft vibration damper mounting process
.After completing damper installation, positioning instrument alignment pin is extracted, positioning instrument is pulled down, smoothly completes the installation of damper.
Trial show that alignment pin need to be only installed on bent axle pin-and-hole and subtracted by the utility model to good pin-and-hole when in use
The step of shaking device pin-and-hole, being required then according to damper mounting process operates the positioning function that can completes damper.Therefore
This instrument is easy to use, saves man-hour.
It should be noted last that above example is only unrestricted to illustrate the technical solution of the utility model, to the greatest extent
The utility model is described in detail with reference to preferred embodiment for pipe, it will be understood by those within the art that, can be with
The technical scheme of utility model is modified or equivalent substitution, without departing from the spirit and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
