Abstract
The utility model discloses a bearing lubricating device for a pump turbine, which comprises an upper bearing pad, a lower bearing pad, a bearing body, a rotating shaft and a lubricating oil conveying device. The rotating shaft is arranged in the bearing body and can rotate relative to the bearing body. The upper bearing pad and the lower bearing pad are arranged on the inner wall of the bearing body and are positioned between the bearing body and the rotating shaft, wherein an lubricating oil passage is formed inside the upper bearing pad; the inner wall of the upper bearing pad is provided with an oil tank; and the oil tank is communicated with the lubricating oil passage. The lubricating oil conveying device comprises a lubricating wheel and an outer shell; the lubricating wheel is fixed on the end face of the rotating shaft; the outer edge of the lubricating wheel is provided with screw threads; the outer edge of the lubricating wheel is sleeved with the outer shell; an oil delivery passage is formed in a gap between the outer shell and the lubricating wheel; and the oil delivery passage is communicated with the lubricating oil passage. The bearing lubricating device can implement an automatic lubricating function; and due to omission of external equipment such as an oil pump and the like, the bearing lubricating device is lower in cost and is safe and reliable.
Description
Technical field
The utility model relates generally to the lube plant of pump turbine.
Background technique
The bearing of large-scale vertical pump turbine rotating shaft adopts sliding bearing usually; usually sliding bearing needs regularly to detect the lubricant oil recoverable amount in the bearing, need shut down when content is low, and by oil hole bearing be injected lubricant oil; to guarantee the sufficient lubrication of sliding bearing, prevent mechanical failure.The inefficiency of lubricant oil is injected in this regular detection and manual operation, can't realize that automatic oiling guarantees lubrication effect.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of pump turbine bearing-lubricating device, and this device can be realized injecting lubricant oil automatically, has improved working efficiency and has avoided shutdown inspection.
Technological scheme: for achieving the above object, the utility model is achieved through the following technical solutions: a kind of pump turbine bearing-lubricating device, comprise top bearing shell, lower bearing bearing support, rotating shaft and lubricant oil feedway, described rotating shaft is located in the bearing support, and can rotate relative to bearing support; Described top bearing shell and lower bearing are located on the bearing support inwall, and are between bearing support and the rotating shaft, and wherein top bearing shell inside is provided with grease channel, and inwall then is provided with oil groove, and this oil groove is communicated with grease channel; Described lubricant oil feedway comprises lubrificated wheels and frame, described lubrificated wheels is fixed on the end face of rotating shaft, and outer rim is provided with screw thread, and described frame is enclosed within on the outer rim of lubrificated wheels, and and the formation of the gap between lubrificated wheels oil transportation channel, this oil transportation channel is communicated with grease channel.
As preferably, described lubricant oil feedway outside also is provided with fuel tank.
Further improve, the inwall of described top bearing shell and lower bearing is coated with the Babbitt wearing layer.
Beneficial effect: the utility model compared with prior art has the following advantages: can realize self-lubricated function; Because save external equipments such as oil pump, cost is lower, and is safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, lubrificated wheels 1, frame 2, top bearing shell 31, lower bearing 32, bearing support 4, rotating shaft 5, fuel tank 6, oil groove 7, grease channel 8, oil transportation channel 9.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1, a kind of pump turbine bearing-lubricating device, comprise top bearing shell 31, lower bearing 32, bearing support 4, rotating shaft 5, lubrificated wheels 1, frame 2 and fuel tank 6, described top bearing shell 31 and lower bearing 32 all have the cast iron cast to form semicircle tile, and be coated with the Babbitt wearing layer on the inwall, thereby can improve wear-resistance of bearing pad, and on the adaptive inwall that is embedded in bearing support 4, described top bearing shell 31 is provided with oil groove 7 in addition, and lower bearing 32 inwalls are level and smooth.And described rotating shaft 5 is in being located at bearing shell, and rotates relative to bearing shell, and bolt is connected with lubrificated wheels 1 on the breech face of rotating shaft 5, and the outer rim of this lubrificated wheels 1 is provided with screw thread, and 2 of described framies are enclosed within on lubrificated wheels 1 outer rim, and are connected and fixed with bearing shell.Wherein top bearing shell 31 inside are provided with grease channel 8, and this grease channel 8 is communicated with oil groove 7, and the gap between frame 2 and the lubrificated wheels 1 forms oil transportation channel 9 simultaneously, and this oil transportation channel 9 is communicated with grease channel 8.In addition, at the outer installment mailbox of lubricant oil feedway, and be loaded with lubricant oil and make the lubricant oil liquid level cover lubrication delivery passage at least.
When work, lubrificated wheels 1 is rotated with rotating shaft 5, and the screw thread on this moment lubrificated wheels 1 outer rim can carry lubricant oil, and by grease channel 8 be transported to rotating shaft 5 respectively and top bearing shell 31 and lower bearing 32 between surface of contact, thereby the formation lubricant film, thereby realize self-lubricated function.Lubricant oil all is to be extracted into the higher position by oil pump in the prior art, and utilizes the lubricant oil self gravitation to be injected into rotating shaft 5 surface of contact by oil pipe, and such mode needs external equipment more, and cost is too high, and there was a mechanical failure easily.And in the utility model because fuel tank 6 is directly arranged in the outside of lubricant oil feedway, so lubricant oil can rotate and the surface of contact that bring into automatically between rotating shaft 5 and the bearing shell provides lubrication with lubrificated wheels 1.Therefore need not external equipments such as oil pump, cost is lower, and is safe and reliable.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
