Abstract
A bath oil lubrication type electric coal drill is characterized in that a main shaft oil seal (12) is installed on a reducer box cover (1) of an existing electric coal drill, a motor reel oil seal (11) is installed on a reducer middle cover (2), a dry type grease lubrication mode of the existing electric coal drill is changed to be a bath oil type gear oil lubrication mode, a screw hole is designed in the side edge of the reducer box cover (1) so as to facilitate oil filling, and a ventilation pipe (13) is installed on the hole through a hollow bolt (14), so that the situation that air pressure is produced and gear oil is squeezed and leaked as internal temperature of a reducer rises when the bath oil lubrication type electric coal drill operates is avoided. Compared with the existing electric coal drill, the bath oil lubrication type electric coal drill has the advantages that a gear and a bearing of the reducer can be fully lubricated when in operation, and the service life can be prolonged greatly.
Description
One, technical field
The utility model belongs to dynamo-electric field, particularly a kind of bath oil lubricating type electric coal drill.
Two, background technique
Present electric coal drill, what retarder adopted is all that dry type is the butter lubricating system, during use, due to lubricated bad, its life-span is shorter.
Three, summary of the invention
The purpose of this utility model is: the technological deficiency existed for existing product, propose a kind of bath oil lubricating type electric coal drill of meter, and overcome above-mentioned deficiency, for realizing this purpose, the technological scheme of employing is as follows:
A kind of bath oil lubricating type electric coal drill, include retarder lid, middle cover, (middle cover is the synthetic parts of End cover for motor and retarder box body) main shaft, mainshaft gear, reducing gear wheel shaft, deceleration gearwheel, reduction pinion teeth, (deceleration gearwheel and reduction pinion teeth are the disjunctor gears) motor, motor gear, bearing, it is characterized in that:
1) it also has motor reel oil sealing, main shaft oil sealing, hollow bolt, breathing pipe;
2) the motor reel oil sealing covers in being arranged on, motor casing is arranged on middle cover back-end, motor gear is fixed on motor reel, and motor reel covers in being arranged on by bearing and motor reel oil sealing;
3) deceleration gearwheel and reduction pinion teeth are arranged on the reducing gear wheel shaft by bearing, and the reducing gear wheel shaft is arranged on middle cover and retarder lid, and the deceleration gearwheel is meshed with motor gear;
4) install on the retarder lid on main shaft oil sealing, main shaft and install that fixing mainshaft gear is meshed with reduction pinion teeth, main shaft is arranged on middle cover by bearing and has on the retarder lid of main shaft oil sealing;
5) be designed with a screw at retarder lid side, for adding gear oil and with hollow bolt, breathing pipe is installed on screw.
During use, the screw by retarder lid side installs the gear oil of some additional, with hollow bolt, breathing pipe is arranged on screw, to prevent that when the work, the retarder inside temperature raises to produce air pressure and squeeze and leaks gear oil.
Bath oil lubricating type electric coal drill of the present utility model, with existing product, compare: reducer gear, bearing can obtain sufficient lubrication, the working life that therefore can greatly improve product when work.
Four, accompanying drawing explanation
Accompanying drawing is a kind of structural representation of bathing the oil lubricating type electric coal drill of the utility model.
---retarder lid, 2---middle cover, 3---main shaft, 4---mainshaft gear, 5---reducing gear wheel shaft, 6---deceleration gearwheel, 7---reduction pinion teeth, 8---motor, 9---motor gear, 10---bearing, 11---motor reel oil sealing, 12---main shaft oil sealing, 13---breathing pipe, 14---hollow bolt in the drawings: 1.
Five, embodiment
Further illustrate concrete structure of the present utility model and its working principle below in conjunction with accompanying drawing.
A kind of bath oil lubricating type electric coal drill, include retarder lid 1, middle cover 2, (middle cover is the synthetic parts of End cover for motor and retarder box body) main shaft 3, mainshaft gear 4, reducing gear wheel shaft 5, deceleration gearwheel 6, reduction pinion teeth 7, (deceleration gearwheel and reduction pinion teeth are the disjunctor gears) motor 8, motor gear 9, bearing 10, it is characterized in that:
1) it also has motor reel oil sealing 11, main shaft oil sealing 12, breathing pipe 13, hollow bolt 14;
2) motor reel oil sealing 11 covers in being arranged on, motor 8 shells are arranged on middle cover 2 rear ends, motor gear 9 is fixed on motor reel, and motor reel is arranged on middle cover 2 by bearing 10 and motor reel oil sealing 11;
3) deceleration gearwheel 6 and reduction pinion teeth 7 are arranged on reducing gear wheel shaft 5 by bearing 10, and reducing gear wheel shaft 5 is arranged on middle cover 2 and retarder lid 1, and deceleration gearwheel 6 is meshed with motor gear 9;
4) install on retarder lid 1 on main shaft oil sealing 12, main shaft 3 and install that fixing mainshaft gear 4 is meshed with reduction pinion teeth 6, main shaft 3 is arranged on middle cover 2 by bearing 10 and has on the retarder lid 1 of main shaft oil sealing 12;
5) be designed with a screw at retarder lid 1 side, for adding gear oil and with hollow bolt 14, breathing pipe 13 is installed on screw.
Its operating principle is: the kinetic energy of motor 8, driving deceleration gearwheel 6 by motor gear 9 rotates, and then make synchronous rotation of reduction pinion teeth 7 and realize primary speed-down, then drive mainshaft gears 4 by reduction pinion teeth 7 and rotate, complete the double reduction of electric drill.
