Abstract
The utility model provides a bearing seat which can prevent dust from entering so as to ensure a bearing not to be abraded. The bearing seat is provided with a shaft hole for a shaft to penetrate; the bearing seat is internally provided with a bearing cavity for arranging the bearing; an air inlet channel in which compressed air can be introduced is formed in the bearing seat; and the outlet of the air inlet channel is positioned on the hole wall of the shaft hole.
Description
Technical field
Present technique relates to bearing support, and it is more abominable to be mainly used in environment, in the more bearing working environment of impurity such as dust, such as the main bearing of centrifuge in cutting workshop section of the line in the photovoltaic industry or the online recovering device of mortar etc.
Background technique
In the photovoltaic industry, because the first-selected abrasive material of silicon chip cutting is a silicon carbide cutting mortar, so a lot of working environment all has the existence of mortar and dust, when bearing working will certainly exert an influence to it in such environment.Therefore the effect of minimizing even isolated abrasive material mortar entering bearing be can play in the design of device bottom brackets such as mortar recovering device, bearing wear degree and working life directly influenced.So we not only will propose specific (special) requirements to the centrifuge bearing, more to higher requirement be proposed to the design of bearing support.Whether the bearing support design reaches the general requirement that requirement also will influence the mortar reclaiming system.
We are through doing further to analyze to bearing support, and at first the charging quantity according to grease has two kinds of forms: a kind of is micro-fuel feeding type, and its contained lubricating grease is the necessary minimum flow of bearing lubrication; Another kind is a volume fuel feeding type, and retainer material (polyethylene and lubricating grease mixture) is filled with bearing interior space.The old-fashioned method that mill trunnion is installed rolling bearing is that quill shaft is processed into the internal diameter that is fit to bearing; The outside of bearing thermic devices, bearing portion, bearing inner ring there is the top cover; The top cover leans on feeding and discharging spiral tube (or feeding and discharging lining) to be fixed by bolts on the quill shaft, compresses.In the mill running; Feeding and discharging spiral tube, fixing bolt are often loosening, have caused top cover and quill shaft to produce displacement, and dust mortar etc. can get in the bearing box from the slit between quill shaft and the top cover; Make lubricating grease dirty; Cause insufficient lubrication, and mortar hardness height can cause the wearing and tearing of bearing, thereby cause the damage of bearing to happen occasionally.
Summary of the invention
The purpose of present technique provides a kind of dust that can prevent and gets into, with the bearing support that guarantees that bearing can not wear and tear.
This bearing support has the axis hole that supplies axle to pass, and has the bearing bore that bearing is set in the bearing support, has in the bearing support and can feed compressed-air actuated gas-entered passageway, and the outlet of this gas-entered passageway is positioned on the hole wall of axis hole.
The beneficial effect of present technique: during use; In bearing support, feed gas through gas-entered passageway; Make to be barotropic state in the bearing support that dust just is difficult to get in the bearing bore through the gap between axle and the axis hole from the outside of bearing support, has prevented the wearing and tearing of the bearing in the bearing bore.
Above-mentioned bearing support, bearing support are divided into upper semi-body and the lower semi-body that removably connects, and said axis hole is made up of with following half axis hole that is positioned on the lower semi-body last half axis hole that is positioned on the upper semi-body; In upper semi-body, be provided with can feed compressed-air actuated on gas-entered passageway, outlet of gas-entered passageway is positioned on the hole wall of half axis hole on this; In lower semi-body, be provided with and can feed compressed-air actuated following gas-entered passageway, the outlet of this time gas-entered passageway is positioned on the hole wall of following half axis hole.The outlet of last gas-entered passageway is first annular exit around first axis hole hole wall; The outlet of following gas-entered passageway is second annular exit around second axis hole hole wall; First annular exit and second annular exit are formed an annular.
Above-mentioned bearing support, two of said axis holes lay respectively at the both sides of bearing bore.
Dust and mortar abrasive material etc. entered into bearing through (machine) axle when present technique had effectively been avoided bearing working, thereby had avoided the wearing and tearing to bearing such as dust and mortar abrasive material, the working life of further improving bearing.

Fig. 2 is the plan view of bearing support.
Fig. 3 is the sectional view of bearing support.
Embodiment
Combine accompanying drawing that present technique is done further to describe through embodiment below.
Referring to the bearing support shown in Fig. 1-3, have the bearing bore 9 that bearing 10 is set in it, two axis holes 8 that supply axle 7 to pass lay respectively at the both sides of bearing bore.Bearing support comprises becoming the upper semi-body 1 removably connect and 2, two axis holes of lower semi-body 8 through bolt each being formed by being positioned at last half axis hole 81 on the upper semi-body and following half axis hole 82 that is positioned on the lower semi-body.In upper semi-body 1, be provided with can feed gas on gas-entered passageway 3, outlet of gas-entered passageway is first annular exit 4 around first axis hole hole wall on this; In lower semi-body, be provided with the following gas-entered passageway 5 that can feed gas, the outlet of this time gas-entered passageway is second annular exit 6 around second axis hole hole wall; First annular exit and second annular exit are formed an annular.Generally speaking, last gas-entered passageway 3 respectively communicates with source of compressed air with following gas-entered passageway 5.
This bearing support can obtain good application in the online reclaiming system of mortar.It mainly designs is in sealed bearing, to increase one deck hollow layer; And from rear end, bearing cap top reservation aperture, lead to pressurized air; Pressurized air gets into hollow layer from small bore end; And from the slit of hollow layer and axle, discharge, cross in the title impurity such as dust mortar at this and drive through wind-force and from the slit, discharge, intercept impurity and get into the effect in the bearing bore thereby reach.
Claims (4)
1. bearing support, this bearing support have an axis hole that supplies axle to pass, and have the bearing bore that bearing is set in the bearing support, and it is characterized in that: have in the bearing support and can feed compressed-air actuated gas-entered passageway, the outlet of this gas-entered passageway is positioned on the hole wall of axis hole.
