Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor with a self-lubricating function. Background Art

[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. It is divided into electric motors (symbol: M) and generators (symbol: G). The direction of the force on the conductor is determined by the left-hand rule. This pair of electromagnetic forces forms a torque acting on the armature. This torque is called electromagnetic torque in a rotating motor. The direction of the torque is counterclockwise, attempting to rotate the armature counterclockwise. If this electromagnetic torque can overcome the resistance torque on the armature (such as the resistance torque caused by friction and other load torques), the armature can rotate in a counterclockwise direction. The working principle of a DC generator is to convert the alternating electromotive force induced in the armature coil into a DC electromotive force when it is drawn out from the brush end by the commutator and the commutation action of the brush;

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example 1

[0028] like Figure 1-4 As shown, the utility model provides a motor with a self-lubricating function, comprising a housing 1, and a lubricating mechanism 2 is arranged inside the housing 1;

[0029] The lubrication mechanism 2 includes a fixed plate 201, a bearing 205 is fixedly connected to the interior of the fixed plate 201, a rotating shaft 204 is fixedly connected to the inner wall of the inner ring of the bearing 205, a top block 216 is fixedly connected to the top of the rotating shaft 204, a mechanism housing 203 is fixedly connected to the right side of the surface of the rotating shaft 204, and an oil storage box 202 is fixedly connected to the top of the mechanism housing 203.

[0030] A slot 206 is provided on the mechanism housing 203, and a fixed shell 207 is fixedly connected to the inner wall of the slot 206. A second oil outlet hole 217 is provided on the fixed shell 207, and an extension tube 209 is fixedly connected to the left end of the second oil outlet hole 217. The mechanism housing 203 can prevent the lubricating oil from splashing everywhere.

[0031] The left end of the inner wall of the fixed shell 207 is fixedly connected to a limiting rod 211 , the surface of the limiting rod 211 is sleeved with an inclined bottom shell 215 , and the inclined bottom shell 215 is provided with a movable groove 210 , and the inclined bottom shell 215 can be fixed and limited by the limiting rod 211 .

[0032] The movable groove 210 is provided with a through hole 212 , a guide rod 214 is inserted into the through hole 212 , a spring 213 is sleeved on the surface of the guide rod 214 , and the inclined bottom shell 215 is restored to its original position by the provided spring 213 .

[0033] In this embodiment, by setting the lubricating mechanism 2, the lubricating oil at the bearing 205 of the motor will dry up after a long period of work. It is only necessary to fill the oil storage box 202 with lubricating oil and then start the motor. When the motor is working, it will drive the rotating shaft 204 to rotate, and the rotating shaft 204 will drive the top block 216 to rotate. When the top block 216 rotates to the top, it will lift the inclined bottom shell 215 so that the first oil outlet hole 208 and the second oil outlet hole 217 overlap, so that the internal lubricating oil passes through the first oil outlet hole 208 and the second oil outlet hole 217. 217 enters the extension tube 209 and drips along the extension tube 209 to between the rotating shaft 204 and the bearing 205 to complete the lubrication work. When the motor stops using, the top block 216 leaves the highest point, and the inclined bottom shell 215 moves downward under the action of the spring 213, so that the first oil outlet 208 and the second oil outlet 217 are offset, thereby stopping lubrication and avoiding the waste of lubricating oil. This mechanism can prevent the transmission efficiency of the motor from decreasing after long-term use, and can avoid the waste of lubricating oil when the motor is not working.

[0034] Example 2

[0035] like Figure 1-4 As shown, based on Example 1, the utility model provides a technical solution: the motor stator 7 is fixedly connected to the inside of the housing 1, and the motor rotor 8 is fixedly connected to the left end of the rotating shaft 204, and the internal parts of the motor can be protected by the setting of the housing 1.

[0036] The inner wall end of the mechanism housing 203 is fixedly connected with a central oblique block 6, the bottom end of the mechanism housing 203 is fixedly connected with a recovery box 3, the front end of the recovery box 3 is fixedly connected with an oil pump 4, the front end of the oil pump 4 is fixedly connected with an oil pipeline 5, and the lubricating oil can be recycled through the provided oil pump 4.

[0037] In this embodiment, when excess lubricating oil falls, the lubricating oil can be introduced into the recovery box 3 through the central inclined block 6. When the liquid level in the recovery box 3 reaches a certain height, the oil pump 4 can be started to pump the lubricating oil into the oil pipe 5, and then the lubricating oil can be introduced into the oil storage box 202 through the oil pipe 5, thereby further reducing the waste of lubricating oil.

[0038] The following is a detailed description of the working principle of this motor with self-lubricating function.

[0039] like Figure 1-4As shown, when in use, through the lubrication mechanism 2, the lubricating oil at the bearing 205 of the motor will dry up after a long period of work. It is only necessary to fill the oil storage box 202 with lubricating oil and then start the motor. When the motor is working, it will drive the rotating shaft 204 to rotate, and the rotating shaft 204 will drive the top block 216 to rotate. When the top block 216 rotates to the top, it will lift the inclined bottom shell 215 so that the first oil outlet hole 208 and the second oil outlet hole 217 overlap, so that the internal lubricating oil passes through the first oil outlet hole 208 and the second oil outlet hole 217. 217 enters the extension tube 209 and drips along the extension tube 209 to between the rotating shaft 204 and the bearing 205 to complete the lubrication work. When the motor stops using, the top block 216 leaves the highest point, and the inclined bottom shell 215 moves downward under the action of the spring 213, so that the first oil outlet hole 208 and the second oil outlet hole 217 are offset, thereby stopping lubrication and avoiding the waste of lubricating oil. This mechanism can prevent the transmission efficiency of the motor from decreasing after long-term use, and can avoid the waste of lubricating oil when the motor is not working.

[0040] By setting the central inclined block 6, when excess lubricating oil falls, the lubricating oil can be introduced into the recovery box 3 through the central inclined block 6. When the liquid level in the recovery box 3 reaches a certain height, the oil pump 4 can be started to pump the lubricating oil into the oil pipe 5, and then the lubricating oil can be introduced into the oil storage box 202 through the oil pipe 5, thereby further reducing the waste of lubricating oil.
