Thrust bearing gasket and processing technology thereof

Technical Field

The invention relates to the field of thrust washers, in particular to a thrust bearing washer and a processing technology thereof.

Background

Thrust bearings are generally composed of two or more thrust washers and a plurality of rolling bodies, the thrust washers are generally divided into a shaft plate and a seat plate, and the rolling bodies are generally combined into a whole by iron or copper retainers in the most common mode. This type of bearing is most commonly a steel ball type thrust bearing. Thrust bearings are designed and used to carry axial loads. They are also referred to as axial bearings. These bearings include a thrust ball bearing, a thrust cylindrical roller bearing, a thrust needle bearing, a thrust tapered roller bearing, and a thrust self-aligning roller bearing.

The thrust gasket is located rolling element one side, and footstep bearing need lubricate the rolling element when using to reinforcing footstep bearing's result of use improves footstep bearing's life.

In the prior art, referring to fig. 1, the thrust washer includes a washer body 1, a mounting ring 2 mounted on the washer body 1, a first oil groove 11 formed in one side of the washer body 1, and a second oil groove 21 formed in the mounting ring 2, wherein the washer body 1 is annularly disposed, one end of the first oil groove 11 is communicated with an inner ring of the washer body 1, the first oil groove 11 is communicated with the second oil groove 21, and an inner ring of the washer body 1 is inserted into a shaft body 3.

Because the opening directions of the first oil groove 11 and the second oil groove 21 face the rolling bodies, after the lubricating oil in the first oil groove 11 and the second oil groove 21 is used up, the first oil groove 31 is filled on the shaft body 3 for convenient oiling again, the lubricating oil is filled into the first oil groove 31 through an oiling tool, and the lubricating oil is separated from the first oil groove 31 and enters the first oil groove 11 and the second oil groove 21 from one end, close to the inner ring of the gasket body 1, of the first oil groove 11 by means of inertia and pressure.

Such mode will need great pressure, just can push oil groove one and oil groove two with more lubricating oil in, in order to pour into more lubricating oil into, increase lubricating oil's thrust and pressure, will need constantly the oiling to in the oiling groove, and these lubricating oil will spill over from the oiling groove lateral wall, can lead to entering into the lubricating oil quantity in oil groove one and the oil groove two not enough like this, need often carry out the oiling to footstep bearing, the oiling groove on the axis body will need the staff to process in advance simultaneously, the injection of lubricating oil brings very big inconvenience for the staff.

Disclosure of Invention

In view of the shortcomings of the prior art, one of the purposes of the present invention is to provide a thrust bearing gasket which is convenient for oil injection and has a large storage capacity of lubricating oil.

The above object of the present invention is achieved by the following technical solutions:

the utility model provides a footstep bearing gasket, includes the gasket body, installs the collar in gasket body one side, seted up oil groove three on the collar lateral wall the filling hole has been seted up on the gasket body lateral wall, the filling hole is perpendicular with gasket body axis direction, the overflow hole has been seted up on the gasket body, overflow hole one end link up with the filling hole, the overflow hole other end link up with oil groove three, oil groove three is the kidney slot.

Through adopting above-mentioned technical scheme, lubricating oil pours into from the filling hole, constantly pour into lubricating oil back into in the filling hole, under the pressure effect, lubricating oil will the upward movement, flow into oil groove three in from the overflow hole, lubricating oil stores in oil groove three, oil groove three is the kidney slot, when the lubricating oil liquid level height in oil groove three is less than the lateral wall at oil groove three notch place, can prevent that lubricating oil from flowing out in oil groove three, when the rolling element during operation, lubricating oil in oil groove three will play the lubrication action to the rolling element, the filling hole that link up each other, overflow hole and oil groove three, can make things convenient for the staff to carry out the oiling, the storage capacity of lubricating oil can be improved to oil groove three of kidney slot shape simultaneously.

The present invention in a preferred example may be further configured to: the filling hole, the overflow hole and the oil groove are all uniformly provided with a plurality of holes along the circumferential direction of the gasket body.

Through adopting above-mentioned technical scheme, the filling hole, overflow hole and the oil groove that evenly set up along gasket body circumferencial direction can make the oiling more even, further make lubricating oil more even to the lubrication of rolling element.

The present invention in a preferred example may be further configured to: an oil storage tank is arranged on the gasket body and is a kidney-shaped tank, and the oil storage tank is communicated with the oil tank III.

Through adopting above-mentioned technical scheme, the oil storage tank is located the gasket body, and the oil storage tank communicates with three of oil grooves, can improve the storage space of lubricating oil to reduce the oiling number of times, save time.

The present invention in a preferred example may be further configured to: an overflow groove is formed in the mounting ring, one end of the overflow groove is communicated with the oil groove III, and the other end of the overflow groove is communicated with the outer side wall of the gasket body.

Through adopting above-mentioned technical scheme, the overflow launder is located oil groove three and deviates from mounting ring inner ring one side, and when the volume increased in oil groove three, the overflow launder played the drainage effect to the interior unnecessary oil mass of oil groove three, prevented that lubricating oil from entering into the inner ring department of mounting ring, caused the pollution.

The present invention in a preferred example may be further configured to: and the circular arc side wall of the gasket body is provided with a circular groove.

Through adopting above-mentioned technical scheme, during the oiling, use the oiling instrument to carry out the oiling to the filling hole, when the oil mass is too much, in some oil can enter into oil groove three from the overflow hole, in addition some oil can be followed the filling hole backward flow, the annular set up to the lubricating oil that flows back and provide the space of depositing, prevent that lubricating oil from flowing out on the gasket body and entering into other work pieces, cause the work piece pollution.

The present invention in a preferred example may be further configured to: the injection hole diameter is larger than the overflow hole diameter.

Through adopting above-mentioned technical scheme, the overflow hole diameter is less than the filling hole diameter, can improve the pressure that enters into the downthehole lubricating oil of overflow to make more lubricating oil enter into oil groove three through the overflow hole.

Aiming at the defects in the prior art, the invention aims to provide the thrust bearing gasket which is convenient to open a groove, is convenient to fill oil and has large lubricating oil storage capacity, and the processing technology thereof.

the machining process applied to the thrust bearing gasket comprises the following steps:
