Description
Technical field
The utility model relates to a kind of lubricant distributor, and it is used for distribute lubrication oil in the lubricating oil path of running shaft, also relates to 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 of being positioned at compressor inside, this lubrication and cooling particular importance concerning compressor for 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, be particular importance for each bearing that is positioned at compressor provides appropriate and uniform lubricant oil for the normal operation of compressor in the operating process 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.Extreme pressure lubricant from lubricating pump enters the axis hole of main shaft 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, the three is lubricated with cooling respectively.
In order to reach desirable lubrication and cooling effect, the distribution of the fuel delivery at three bearing places seems crucial especially.Yet in existing structural design, exist lubricants capacity to distribute uneven problem.At first, when compressor is in when running up state, lubricant oil flows too fast in eccentric oil circuit, cause most of lubricant oil all to flow to by straight oil circuit the driving bearing that is in the main shaft least significant end, thereby the main bearing that makes side branch by straight oil circuit obtain lubricant oil only is transferred a small amount of lubricant oil, even is in the oil starvation state.This probably causes the main bearing over-heating erosion, even causes main bearing to lose efficacy.And when less and main shaft was in the low-speed running state when total fuel delivery of compressor, lubricant oil can not arrive driving bearing because the eccentric force that is subject to is less, even can not arrive main bearing, thereby cause the lack of lubrication of driving bearing or main bearing.When temporarily having namely can guarantee to run up in prior art, lubricant oil can between base bearing, main bearing and driving bearing in reasonable distribution, can not guaranteed the technology of uniform distribution lubricant oil in the time of can guaranteeing and low-speed running less at total fuel delivery yet.The new oil groove design that the utility model proposes can address the above problem, thereby can enlarge the Applicable scope of compressor, improve the working life of operating condition and the prolongation compressor of compressor.
The model utility content
Technical problem to be solved in the utility model is: a kind of lubricant distributor that is intended to eliminate or alleviate at least 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 also is provided.
According to an aspect of the present utility model, a kind of lubricant distributor is provided, this lubricant distributor is arranged in lubricating oil path regularly, be used for distribute lubrication oil in lubricating oil path, lubricant distributor comprises minute oily dividing plate and an oil retaining part, forms at least two grease channels by means of a minute oily dividing plate in lubricating oil path, at least two grease channels and different lubricant oil tributary circuit connection.
