Abstract
The utility model relates to a high-temperature resisting bearing lubrication device for a chemical mixer. The lubrication device comprises a bearing support, a bearing cap and a rolling bearing, wherein a lubricating powder filler port is formed on the bearing cap or the bearing support; a filler nozzle is mounted in the filler port; a flow guide tube communicated with the lubricating powder filler nozzle is mounted on the inner side of the bearing cap or the bearing support; the discharge port of the flow guide tube extends into the inner edge of the bearing outer ring; and lubricating powder is filled in the rolling bearing. The lubrication device can effectively lubricate the bearing of a mixer under high temperature and in corrosion state, thereby greatly prolonging the service life and the lubrication maintenance period of the bearing of the mixer, improving the production efficiency, and achieving convenient use and safe and reliable performance.
Description
Technical field
The utility model belongs to technical field of bearings, is the high temperature resistant bearing-lubricating device of a kind of chemical industry stirrer.
Background technique
In the whipping process of chemical material, a large amount of heat energy that can discharge as caustic soda, potassium permanganate, manganese dioxide etc., the retarder output terminal bearing temperature that makes stirrer stir main shaft bearing and be attached thereto is up to 300～500 ℃ even higher, and to the lubricating grease of the lubricated employing of stirrer bearing, its evaporativity is all lower, Applicable temperature is generally below 100 ℃, even if adopt existing high temperature resistant lubricating grease, its Applicable temperature also has only 200 ℃.Therefore; in the stirrer running; the decline of lubricating grease stickiness, evaporation and chemical corrosion phenomenon often appear; cause lubrication failure, maximum 2 weeks must shut down, and pull down the cleaned and changed lubricating grease of bearing; safeguard untimely slightly; then cause the bearing dry friction and damage, lead to stopping accident, have a strong impact on manufacturing efficiency.Up to now, this problem does not obtain comparatively desirable solution as yet.
The model utility content
The purpose of this utility model provides a kind of can the adaptation under the condition of high temperature and works, prolong the working life and the lubricated maintenance cycle thereof of stirrer bearing effectively, enhance productivity, and the high temperature resistant bearing-lubricating device of chemical industry stirrer esy to use, safe and reliable.
Realize that the technological scheme that the purpose of this utility model is taked is: this device comprises bearing support, bearing cap, rolling bearing, wherein, on bearing cap or bearing support, be provided with the powdered lubricant filler port, refueling nozzle is housed in the filler port, the honeycomb duct that is communicated with the powdered lubricant refueling nozzle is equipped with in the inboard of bearing cap or bearing support, the discharge port of this honeycomb duct put in bearing outer ring in the edge, be marked with powdered lubricant in the rolling bearing.
Described powdered lubricant adopts plumbago or French chalk or plumbago and talcous mixed-powder, and plumbago and talcous granularity are all at 500～800 orders.
The quantity of described powdered lubricant filler port is 2～6.
The high temperature resistant bearing-lubricating device of making according to such scheme of chemical industry stirrer, employing has the high temperature resistant powdered lubricant of multiple premium properties, can be under high temperature and etch state, assurance is to stirrer bearing effective lubricating, thereby prolong the working life and the lubricated maintenance cycle thereof of stirrer bearing greatly, enhance productivity, and esy to use, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the high temperature resistant bearing-lubricating device of chemical industry stirrer of the present utility model, comprise the bearing support 3 that is installed on the stirrer stirring main shaft 1, bearing cap 4 and rolling bearing 2, wherein, on bearing cap 4, be provided with 2～6 powdered lubricant filler ports 5, when adopting the duplex bearing transmission, also powdered lubricant filler port 5 can be arranged on the bearing support 3 with two bearings between corresponding position, this filler port is equipped with powdered lubricant refueling nozzle 6, refueling nozzle can adopt common lubricating grease fuel filler neck, and can utilize conventional grease adding pressure gun to be lubricated the pressure injection of powder, because the powdered lubricant flowability is poorer slightly than lubricating grease, during apolegamy powdered lubricant refueling nozzle 6, the lubricating grease fuel filler neck of the comparable same model coordinative composition of equipments in its aperture is big 1～No. 2.In order to guarantee powdered lubricant is filled into the friction position of bearing ball or roller, bearing is carried out effective lubricating, the honeycomb duct 7 that can be communicated with powdered lubricant refueling nozzle 6 in the installed inside of bearing cap 4 or bearing support 3, and with the discharge port of honeycomb duct 7 put in rolling bearing 2 outer rings in the edge, preferably make discharge port concordant with the end face of rolling bearing 2 inner rings.In this case, the powdered lubricants such as mixed-powder of filling plumbago or French chalk or plumbago and any proportioning of French chalk in rolling bearing 2, plumbago and talcous granularity are all at 500～800 orders.This case selects for use plumbago and French chalk as powdered lubricant; all have high melt point, wear resistance, adsorptivity, lubricity, ductility and physical and chemical stability; therefore; in use can not only be high temperature resistant; and can evenly and securely be adsorbed on bearing ball or roller surface, it is carried out excellent protection.Simultaneously, the powdered lubricant of selecting for use be granularity at 500～800 purpose micro mists, can guarantee thus its filling and running in flowability, the also corresponding enhancing of its greasy property.
Claims (2)
1. high temperature resistant bearing-lubricating device of chemical industry stirrer, comprise bearing support, bearing cap, rolling bearing, it is characterized in that: on bearing cap or bearing support, be provided with the powdered lubricant filler port, refueling nozzle is housed in the filler port, the honeycomb duct that is communicated with the powdered lubricant refueling nozzle is equipped with in the inboard of bearing cap or bearing support, the discharge port of this honeycomb duct put in bearing outer ring in the edge, be marked with powdered lubricant in the rolling bearing.
2. the high temperature resistant bearing-lubricating device of chemical industry stirrer according to claim 1 is characterized in that: the quantity of described powdered lubricant filler port is 2～6.
