By adopting the large-scale direct current motor of the utility model, the manufacturing cost of the oil thrower is saved; the weight of parts is reduced by adopting a radial plate type design, and the load rate is reduced; meanwhile, the disassembly and the replacement are convenient.
Description
Technical Field
The utility model relates to an oil thrower dish for large-scale direct current motor.
Background
The oil slinger is an indispensable component in the bearing structure of the motor. The main function of the oil scraper is to move low-pressure oil in the bearing along the oil thrower, scrape a small part of oil down to the storage oil tank through the matching with the oil scraper at the top, and then enable the oil to flow downwards from top to bottom through the storage oil tank, so that the comprehensive coverage of an oil film is realized, and a good lubricating effect is ensured, and the importance of the oil scraper is self-evident. The oil thrower disc of the traditional large-scale direct current motor is generally arranged on the shaft diameter and is not fixedly assembled and is arranged inside a direct current motor bearing, and the working principle is that the oil thrower disc is driven to rotate by utilizing the rotation of a shaft per se in a friction mode, so that low-pressure oil of an oil tank in the bearing is brought into the upper bearing bush. Because the oil is rotationally brought by friction, the rotation state of the oil thrower is unstable, so that the oil throwing effect is general and the lubricating efficiency is general.
Disclosure of Invention
The utility model aims at designing a be convenient for dismantle and change, low price, weight are lighter and lubricated better hydro-extracting disc that is used for large-scale direct current motor of effect. The technical scheme of the utility model is that: the utility model provides an oil slinger for large-scale DC motor, oil slinger (4) constitute for two semicircular steel spare fixed connection that the structure is the same, left side cold drawn steel pipe (1) and left oil tank (2) intercommunication, oil wiper (3) are fixed outside oil slinger (4) dish, oil wiper (3) and oil slinger (4) are clearance fit, oil wiper (3) are respectively through pipeline and left oil tank (2), right oil tank (5) intercommunication, right oil tank (5) and right cold drawn steel pipe (6) intercommunication, oil slinger (4) are through connecting pin (8) and axle (7) fixed connection, cylindric lock (9) are installed on oil slinger (4), right cold drawn steel pipe (6) are connected to axle bush (10) oil circuit hole, the clearance of axle (7) and thrust axle bush (11) is as the oil circuit and is connected left cold drawn steel pipe (1).
The oil thrower wheel (4) is fixedly assembled with the connecting hole (14) through a bolt (12) and a nut (13).
The utility model discloses the theory of operation:
the cylindrical pin (9) is fixed in the oil thrower disc (4) in an ocean impact mode, so that the axial displacement of the connecting pin (8) is prevented; the rotating oil thrower wheel (4) is matched with the oil scraper (3) to divide oil into a left oil tank (2) and a right oil tank (5), the oil in the left oil tank (2) flows into a gap between a shaft (7) and a thrust bearing bush (11) through a left cold-drawn steel pipe (1), and the oil in the right oil tank (5) flows into an oil way hole of a bearing bush (10) through a right cold-drawn steel pipe (6), so that the outer diameter of the shaft (7) flows to realize the covering of lubricating oil on the shaft body.
The utility model discloses the advantage of structure:
the oil thrower (4) 1 is fixedly assembled with the connecting hole (14) through the bolt (12) and the nut (13), the fixing structure is simple, and the used parts are common general parts and are convenient to detach and replace.
2 disc (4) adopts rigid material, practices thrift the cost, adopts the spoke plate formula mode to design simultaneously, reduces disc weight itself, reduces the load factor.
Oil driven by the oil throwing disc (4) 3 is distributed to the left oil tank (2) and the right oil tank (5) through the matching of the oil scraper (3), so that the oil flows to the outer diameter of the shaft (7) through the left cold-drawn steel pipe (1) and the right cold-drawn steel pipe (6) which are connected with the oil tanks.
Description of the drawings:
FIG. 1 is a sectional view showing the structure of the present invention;
FIG. 2 is a front view of the oil slinger (4) of FIG. 1;
fig. 3 is an enlarged view of portion i of fig. 2.
Detailed Description
As shown in figure 1, the oil thrower disc 4 is formed by fixedly connecting two semicircular steel pieces with the same structure, a left cold-drawn steel pipe 1 is communicated with a left oil tank 2, an oil scraper 3 is fixed outside the disc body of the oil thrower disc 4, as shown in figure 2, the oil scraper 3 is in clearance fit with the oil thrower disc 4, the oil scraper 3 is respectively communicated with the left oil tank 2 and the right oil tank 5 through pipelines, the right oil tank 5 is communicated with a right cold-drawn steel pipe 6, the oil thrower disc 4 is fixedly connected with a shaft 7 through a connecting pin 8, a cylindrical pin 9 is installed on the oil thrower disc 4, an oil way hole of a bearing bush 10 is connected with the right cold-drawn steel pipe 6, and a gap between the shaft 7 and a thrust bearing bush 11 is used as an oil way.
As shown in fig. 3, the oil thrower 4 is fixedly fitted to the attachment hole 14 by means of a bolt 12 and a nut 13.
