Abstract
The invention relates to a lubricating oil distribution device which is fixedly arranged in a lubricating oil path and is used for distributing lubricating oil in the lubricating oil path. The lubricating oil distribution device can forcedly divide the lubricating oil in the lubricating oil path into a plurality of parts which are respectively communicated with parts needing to be lubricated, and the uneven distribution of the lubricating oil among the parts is avoided. It also relates to a compressor main shaft comprising such a lubricating oil distribution device and to a corresponding compressor.
Description
Technical field
The present invention relates to a kind of lubricant distributor, it also relates to for distribute lubrication oil in the lubricating oil path of running shaft the compressor main shaft and the corresponding compressor that comprise this lubricant distributor.
Background technique
In the prior art, a kind of lubrication system of horizontal type scroll compressor be lubricant oil under the effect of the pressure reduction between hyperbaric chamber and low-pressure cavity, by specific grease channel, form the circulatory system of a sealing.In this circulating oil system, lubricant oil is lubricated with cooling the bearing of each position that is positioned at compressor inside, for this lubrication and cooling particular importance concerning compressor of bearing, cross the over-heating erosion that a small amount of lubricant oil especially easily causes bearing, even burn out, and cause thus the decline of compressor performance, even cause compressor failure.In addition, the lubricant oil of crossing volume not only can cause the too much waste of lubricant oil, and can make the running of bearing receive larger resistance, thereby causes the too much consumption of energy.Therefore, in the operating process of compressor, in order to be positioned at each bearing of compressor, appropriate and uniform lubricant oil is provided is particular importance for the normal operation of compressor.
In existing compressor, generally realize transmission and the circulation of lubricant oil by the eccentric oil circuit in the main shaft of compressor.Enter the axis hole of main shaft from the extreme pressure lubricant of lubricating pump by pipeline and cup structure of extraction, enter subsequently the eccentric oil circuit in main shaft.Under the effect of eccentric force, lubricant oil flows to the other end of main shaft from the lower shaft socket end of main shaft.In the flow process of lubricant oil, lubricant oil successively flow through base bearing, main bearing and driving bearing, and by corresponding oil outlet, three is lubricated with cooling respectively.
In order to reach desirable lubrication and cooling effect, it is crucial especially that the distribution of the fuel delivery at three bearing places seems.But in existing structural design, exist lubricants capacity to distribute uneven problem.First, when compressor is in the time running up state, lubricant oil flows too fast in eccentric oil circuit, cause most of lubricant oil all to flow to the driving bearing in main shaft least significant end by straight oil circuit, thereby make the main bearing that is obtained lubricant oil by the side branch of straight oil circuit only be transferred a small amount of lubricant oil, even in oil starvation state.This probably causes main bearing over-heating erosion, even causes main bearing to lose efficacy.And when total fuel delivery of compressor is less and main shaft during in low-speed running state, lubricant oil, because the eccentric force being subject to is compared with little and can not arrive driving bearing, even can not arrives main bearing, thereby cause the lack of lubrication of driving bearing or main bearing.Temporarily can not guarantee to run up in prior art time, lubricant oil can be between base bearing, main bearing and driving bearing in reasonable distribution, can guarantee the technology of uniform distribution lubricant oil also can guarantee and low-speed running less at total fuel delivery time.The new oil groove design that the present invention proposes can address the above problem, thereby can expand the Applicable scope of compressor, improve the working life of operating condition and the prolongation compressor of compressor.
Summary of the invention
Technical problem to be solved by this invention is: a kind of lubricant distributor that is intended to eliminate or at least alleviate existing at least one shortcoming in above-mentioned prior art is provided, a kind of compressor main shaft and a kind of compressor that comprises above-mentioned main shaft that comprises this lubricant distributor is also provided.
According to an aspect of the present invention, a kind of lubricant distributor is provided, this lubricant distributor is arranged in lubricating oil path regularly, for distribute lubrication oil in lubricating oil path, lubricant distributor comprises point oily dividing plate and an oil retaining part, in lubricating oil path, form at least two grease channels by means of a point oily dividing plate, at least two grease channels are communicated with from different lubricant oil tributary circuits.
According to the preferred embodiment of lubricant distributor of the present invention, the lubricant distributor being arranged in lubricating oil path can be divided at least two parts by the lubricant oil in oil circuit by its point of oily dividing plate, thereby the lubricated parts of multiple needs are lubricated with cooling, and in corresponding position, oil retaining part is set, lubricant oil can be directed to corresponding lubricant oil tributary circuit, thus avoid due to the high-speed rotary of axle then make lubricant oil from lubricant oil tributary circuit fast by and only have a small amount of lubricant oil to flow into the situation of lubricant oil tributary circuit.Lubricant oil can be uniformly distributed to more to multiple lubricant oil tributary circuits according to lubricant distributor of the present invention, thereby make the impact of the lubricated rotating speed, oil body and the temperature that are not subject to axle on each lubricated part, can extend thus the working life of all parts.
According to a further aspect in the invention, provide a kind of main shaft for compressor, this main shaft comprises lubricant distributor as above, and this lubricant distributor is arranged in the eccentric oil circuit of main shaft.Can make lubricant oil in eccentric oil circuit be uniformly distributed to each block bearing of compressor according to the main shaft for compressor of the present invention, avoid the driving bearing lubricants capacity that runs up in situation at main shaft in prior art too much, and the very few defect of main bearing place lubricants capacity, thereby guarantee the good lubrication of two place's bearings and cooling, extended the working life of bearing.
According to an also aspect of the present invention, a kind of compressor is provided, this compressor comprises main shaft as above.
