Abstract
The utility model discloses a motor with a bearing water cooling structure, which comprises an end cover (1). A water inlet passage (4) and a water outlet passage (5) are arranged on the end cover (1) and respectively communicated with an annular water cavity (6) on the end cover (1), a water-stop plate (3) is arranged between communicating positions of the annular water cavity (6) with the water inlet passage (4) and the water outlet passage (5), and an annular water retaining ring (2) is arranged on the annular water cavity (6). By adopting the structure, the motor with a bearing water cooling structure can effectively lower running temperature of a bearing inside the end cover and guaranteeing running reliability of the bearing of the motor, thereby being capable of prolonging service life of the motor.
Description
Technical field
The utility model relates to a kind of motor component structure, relates in particular to a kind of motor with bearing water cooling structure.
Background technology
Talk about publicly knownly, in design of electrical motor, motor temperature control is very important.At present, for rotating speed is the speed adjustable DC motor of 12000r/min, very high owing to rotating speed in running, cause the speed of motor bearings also very high, the corresponding temperature that produces is also very high, if it is bad that the cooling measure of bearing is done, can significantly reduce the useful life of bearing, final result is to shorten greatly the useful life of motor.Therefore, the design of bearing cooling device is most important.In general design of electrical motor, be to adopt whole air-cooled, water-cooled or casing water-cooling structure to reach the effect of whole cooling, but this is for rotating speed is not very high design of electrical motor.For high-speed electric expreess locomotive, these cooling provisions can not well reduce the temperature of bearing.
Summary of the invention
The purpose of this utility model provides a kind of motor with bearing water cooling structure that can effectively reduce bearing temperature.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises end cap, described end cap is provided with intake tunnel and exhalant canal, intake tunnel, exhalant canal are connected with annular water chamber on the end cap respectively, annular water chamber is provided with water-stop sheet being communicated with intake tunnel, exhalant canal between the position, annular retaining ring is set above the annular water chamber.
The said structure that the utility model adopts can effectively reduce the bearing operating temperature in the end cap, has guaranteed the motor bearings reliability of operation, thereby can improve the useful life of motor.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Figure 1 shows that structural representation of the present utility model
Figure 2 shows that the A-A cut-away view among Fig. 1
Embodiment
By accompanying drawing as can be known, this motor with bearing water cooling structure comprises end cap 1, described end cap 1 is provided with intake tunnel 4 and exhalant canal 5, intake tunnel 4, exhalant canal 5 are connected with annular water chamber 6 on the end cap 1 respectively, annular water chamber 6 is provided with water-stop sheet 3 being communicated with intake tunnel 4, exhalant canal 5 between the position, annular retaining ring 2 is set above the annular water chamber 6.The annular retaining ring is enclosed in cooling water in the annular water chamber.Intake tunnel mouth and exhalant canal mouth connect with water tank by flexible pipe.When motor in high-speed cruising, by flexible pipe the water that cools off in the water tank is charged into annular water chamber from intake tunnel, because the iris action of water-stop sheet, cooling water is walked around in the time of moving a circle heat on the bearing is taken away, and get back to water tank, cooling by exhalant canal, so circulation makes bearing keep certain temperature.The utility model structure can design on the front and rear cover of motor simultaneously.
Claims (1)
1. motor with bearing water cooling structure, comprise end cap, it is characterized in that: described end cap is provided with intake tunnel and exhalant canal, intake tunnel, exhalant canal are connected with annular water chamber on the end cap respectively, annular water chamber is provided with water-stop sheet being communicated with intake tunnel, exhalant canal between the position, annular retaining ring is set above the annular water chamber.
