Abstract
The utility model discloses a pre-lubricating, repairing and maintaining device of a main bearing cap of a diesel engine. Firstly, the bottom part of a tooling hole in the main bearing cover is drilled for maintaining before pre-lubricating oil is injected or the diesel engine is loaded, and then sealed through combination of a flange, a plug screw and a pressing plug screw. The pre-lubricating, repairing and maintaining device is simple in operation, simple and obvious in use effect, good in economical efficiency, long in lubricating antirust time, wide in applicability and excellent in application prospect; auxiliary equipment is not needed; use of a lot of lubricating oil materials can be saved; and repair and maintenance of a machine are facilitated. In addition, the pre-lubricating, repairing and maintaining device can be applied to diesel engines of various model numbers.
Description
Technical field
The utility model belongs to diesel engine assembly technical field, relates to especially a kind of diesel engine main bearing cover pre-lubrication and cable maintenance device.
Background technique
RT-flex48T-D main bearing lubrication system architecture according to present routine, before the diesel engine string oil, bearing must be coated with Omega steam cylinder oil or other similar lubricating and antirust material on its crankshaft main-shaft diameters, so that can keep good lubricating and antirust state during the main frame jiggering.Wherein, diesel engine is in assembly process, bent axle hangs in before the support, Omega steam cylinder oil can the main shaft diameter that be coated in bent axle of Direct Uniform on, and the diesel engine after the test run is complete machine shipping or minute two large part shippings mostly, so the method the when lubricating and antirust of main bearing can not use assembling need to arrange special-purpose lubricating oil pipeline, lubrication oil is introduced main bearing by certain pipeline path be lubricated antirust.And because lubricating oil pipeline need to adopt the devices such as lubricating pump, flexible pipe, power source, so comparison in equipment is numerous and diverse, wayward, waste easily a large amount of lubricant oil, wherein because the price of lubricating and antirust material is all relatively more expensive, therefore also increased a lot of cost of production.Simultaneously on the other hand, after the diesel engine oiling, the lubricant oil solution absorption be coated in Omega steam cylinder oil on the bent axle, remain in the effect that As time goes on lubricant oil on the crankshaft main-shaft diameters can lose lubricating and antirust gradually during test run.And the structure of present crank spindle watt is thin-wall bearing shell, alloy coat is white metal or Sn-Al alloy, surface roughness and bearing down suction to main shaft diameter require especially high, if maintaining is improper, cause that main shaft diameter is got rusty or main shaft diameter and main axle bush are pulled, the lubricated and cooling effect of main bearing when directly affecting the diesel engine operation, and then have a strong impact on working life of main bearing, shorten the maintenance cycle of main frame, increase the maintaining cost.
For defects, multiple solution is provided in the industry, commonly used have such as: directly the hole of main bearing lubrication rust preventive material by main bearing cap poured in the main bearing, a whole like this machine probably needs 3 liters of lubricant oil, it is simple to operate, good economy performance, but the lubricating and antirust time is shorter, can't reach good maintaining effect.For another example: use grease gun that viscosity Omega steam cylinder oil or other the similar lubricating and antirust material suitable with CC30 lubricant oil are injected in the main bearing, its lubricating and antirust time is longer, operate also fairly simplely, but cost is higher, is unfavorable for reducing whole cost of production.
The model utility content
The purpose of this utility model is to solve problems of the prior art, and a kind of diesel engine main bearing cover pre-lubrication and cable maintenance device are provided.
The utility model is achieved by the following technical programs:
A kind of diesel engine main bearing cover pre-lubrication and cable maintenance device, at first the bottom with the frock screw on the main bearing cap drills, and is used for pouring into pre-lubrication or carrying out diesel engine and safeguard Before Loading the guarantor, again by flange, plug screw, compression plug screw combination seal.
Concrete, in the frock screw, fill in plug screw, plug screw tightens with the 1-shaped open screw-driver; Plug screw is provided with the compression plug screw, plays the effect that further presses solidly.
In addition, compress the covering of plug screw top and be provided with flange, the flange top is provided with latch, is arranged with two groups of fixedly bolts of usefulness on the latch.
Wherein, screw bolt passes latch, flange also extend in the diesel engine main bearing cover, play fixation.
The utility model usefulness is:
The utility model is simple to operate and do not need to adopt miscellaneous equipment to assist, using effect is simple and easy obviously, can save the use of a large amount of lubricant oil materials, good economy performance, its lubricating and antirust time of while is longer, is conducive to the maintenance of machine, can extend in addition on the diesel engine that is used in Multiple Type, applicability is extensive, possesses better application prospect.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Be illustrated in figure 1 as a kind of diesel engine main bearing cover pre-lubrication and the cable maintenance device that can be used as the utility model preferred embodiment, at first the bottom with the frock screw 6 on the main bearing cap drills, be used for pouring into pre-lubrication or carrying out Before Loading maintaining of diesel engine, again by flange 3, plug screw 5, compression plug screw 4 combination seals.
Concrete, in frock screw 6, fill in plug screw 5, plug screw 5 usefulness 1-shaped open screw-drivers tighten; Plug screw 5 is provided with and compresses plug screw 4, plays the effect that further presses solidly.In addition, compress the covering of plug screw 4 tops and be provided with flange 3, flange 3 tops are provided with latch 2, are arranged with two groups of fixedly bolts 1 of usefulness on the latch 2.
Described bolt 1 passes successively latch 2, flange 3 and extends in the diesel engine main bearing cover, plays fixation, and bolt 1 is take hexagon head bolt as good.
In the production, when the dismounting main bearing cap, pull down latch 2, flange 3 and compress plug screw 4, stay plug screw 5, fall in the main bearing cap to prevent foreign material.
And after test run finishes, take bolt 1, latch 2, flange 3 apart, compress plug screw 4 and plug screw 5, in main bearing, pour into viscosity Omega steam cylinder oil or other the similar lubricating and antirust material suitable with CC30 lubricant oil by frock screw 6, the while jiggering, until crankshaft rotating one circle, the main shaft diameter circumferencial direction is covered with till the lubriation material uniformly, and then plug screw 5, compression plug screw 4, flange 3, latch 2 and bolt 1 are installed successively.In actual production, take 48 diesel engines as example, approximately need to pour into 0.5 liter of lubriation material at every turn and can satisfy need of production, material there has been obvious saving effect.
The utility model goes for cylinder bore greater than RTA and the RT-flex serial diesel engine of 480mm, also can suitably extend according to demand its using scope to relevant industries.
