Abstract
The invention discloses a method for detecting bearing oil content and an apparatus matched with the method. By taking the principle for detecting oil content of an oil-containing bearing as a design basis, taking stainless steel as a raw material and taking a vacuum-pumping device as an auxiliary device, the oil-containing bearing oil content detection apparatus is manufactured, and the problems in the prior art are solved that oil-containing bearing detection apparatuses are expensive and detection methods are complex.
Description
Technical field
The present invention relates to the method and apparatus that a kind of bearing oil content detects, relate in particular to the method and apparatus that a kind of oiliness bearing oil content detects.
Background technology
Oiliness bearing, i.e. porous bearings, take metal powder as primary raw material, with the sintered body that powder metallurgic method is made, it was exactly Porous originally, and have can be than the quantity of free adjustment hole, size, shape and distribution etc. in manufacture process; Utilize the poriness of sintered body, make it impregnation 10% ~ 40% (volume fraction) lubricating oil, under voluntarily for oil condition.。During running, bearing temperature raises, and because the expansion coefficient of oil is larger than metal, thereby automatically enters slidingsurface with lubricating bearings, and while quitting work, oil is again with the sucked back hole of temperature decline.
Oiliness bearing have cost low, can absorbing, noise is little, than the farm labourer, doing in the time without characteristics such as apply oils, be specially adapted to be difficult for lubricated or do not allow the dirty working environment of oil.Factor of porosity is an important parameter of oiliness bearing, and the oiliness bearing of working under high speed, underloading requires oleaginousness many, and factor of porosity should be high; Oiliness bearing desired strength in the more lower work of low speed, load is high, factor of porosity should be low, porosity is a very important parameter for oiliness bearing, the porosity of oiliness bearing is that the oil content by oiliness bearing reacts, so in the manufacturing of oiliness bearing, the detection operation of oil content is extremely important, domestic enterprise is expensive manufacturing of oiliness bearing oil content checkout equipment at present, complicated operation, be difficult to universal.
Summary of the invention
The detection method and a kind of oiliness bearing oil content pick-up unit simple in structure, low-cost that the purpose of this invention is to provide a kind of oiliness bearing oil content simple to operate.
The technical solution used in the present invention is: a kind of method that bearing oil content detects, and implementation step:
(a) measure the workpiece for measurement quality and be designated as m1;
(b) workpiece for measurement is put into to airtight container, the air in the airtight container of finding time;
(c) will detect solvent packs in airtight container;
(d) find time detection solvent and air in airtight container;
(e) take out workpiece for measurement, after oven dry, measure the workpiece for measurement quality m2 of this moment;
(f) by (m2-m1)/m1 formula, calculate the oil content of oiliness bearing.
The device that a kind of bearing oil content detection method matches, this device comprise oil-feed tank, the container cell of pipe connection successively and go out oil groove; On the gland bonnet of described container cell, pipe is connected with vacuum extractor and is fixed with tensimeter.
As a further improvement on the present invention, be used on the pipeline of managing connection, being equipped with ball valve.
As a further improvement on the present invention, the container cell material is stainless steel.
As a further improvement on the present invention, gland bonnet is that flange is connected with the pond body of container cell.
As a further improvement on the present invention, the detection solvent in step (c) is machine oil.
The invention has the beneficial effects as follows: as foundation, of the present invention method is simple to operate according to the detection principle of oiliness bearing oil content, detects effect remarkable, and be higher by the detected product cost performance of the method; Think that with it supporting apparatus structure is simple, stainless steel is as starting material, prevents that effectively the measured workpiece inclusion-free from polluting, and simultaneously, it is large that container cell is added loading amount, can disposable measurement various parts; Gland bonnet is connected with container cell pond body flange, the sealing while effectively having guaranteed device work; Be furnished with and vacuumize, the central gas of workpiece for measurement is all discharged, it is more accurate to make to detect; This device is installed simple, in use is easy to installation, maintenance, maintenance and cost of manufacture cheap, and the price on market has more advantage.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of apparatus of the present invention.
Shown in figure: 1 container cell, 2 oil-feed tanks, 3 go out oil groove, 4 vacuum extractors, 5 ball valves, 6 tensimeters, 7 gland bonnets.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is elaborated.
The method of using the bearing oil content to detect in bearing oil content pick-up unit, implementation step:
The first step, measurement workpiece for measurement quality are designated as m1;
Second step, workpiece for measurement is put into to container cell 1, close gland bonnet 7, open the ball valve on container cell 1 and vacuum extractor 4 connecting tubes, start vacuum extractor 4, container cell 1 is vacuumized;
The 3rd step, when the numerical value of tensimeter 6 arrives assigned address, ball valve and vacuum extractor 4 on closing containers pond 1 and vacuum extractor 4 connecting tubes;
The 4th step, open the ball valve on oil-feed tank 2 and container cell 1 connecting tube, the machine oil in oil-feed tank 2 is entered in container cell 1;
The 5th step, close the ball valve on oil-feed tank 2 and container cell 1 connecting tube, open ball valve on container cell 1 and vacuum extractor 4 connecting tubes and container cell 1 and go out the ball valve on oil groove 3 connecting tubes, by the machine oil in container cell 1 and Bas Discharged;
The 6th walks, opens gland bonnet 7, takes out oiliness bearing, after oven dry, measures the quality m2 of oiliness bearing at this moment;
The 7th walks, by (m2-m1)/m1 formula, calculates the oil content of oiliness bearing.
As shown in Figure 1, a kind of device of bearing oil content detection method, this device comprise oil-feed tank 2, the container cell 1 of pipe connection successively and go out oil groove 3; On the gland bonnet 7 of described container cell 1, pipe is connected with vacuum extractor 4 and on gland bonnet 7, is provided with tensimeter 6.
In order to solve the backflow of oil plant and air, on the pipeline be used to managing connection, be equipped with ball valve 5.
The container of placing workpiece for measurement must have resistance to compression and corrosion resistant character, so container cell 1 material is stainless steel.
In order to improve the sealing of container cell 1, gland bonnet 7 is that flange is connected with the pond body of container cell 1, and flange connections is provided with O-ring seal.
The present invention has effectively solved about the oil content checkout equipment price on market high, the situation of complex operation.And whole device is detachable, is easy to install, safeguards, manages.The armamentarium part is all to use stainless steel as starting material, and corrosion-resistant, detecting workpiece therein can be not contaminated, and measurement result is more accurate.
