Description

Technical Field

[0001] The utility model belongs to the technical field of motor devices, and particularly relates to a power device for a new type of cleaning machine. Background Art

[0002] At present, for household swashplate pumps of cleaning machines equipped with induction motors, the induction motors are directly used to drive the pumps to operate. For example, the Chinese invention patent with the patent number CN202010140530.1 discloses a motor pump unit for a high-pressure cleaning machine suitable for internal meshing reduction drive. In addition, the inner-rotor type DC motor pump also uses the motor to directly drive the pump to work. Because countries such as the United States and Japan use low-voltage power supply, the inner-rotor type DC motor pumps generally use lithium batteries for power supply. For these reasons, the current of the motor is restricted. Especially due to the particularity of the cleaning machine (overflow valve structure), a large current is required to start the motor. Therefore, such cleaning machines cannot achieve high pressure and high flow states. And because the current energy storage technology is relatively popular at present, due to economic cost reasons, energy storage cannot generally achieve high-power states. Most of the current energy storage (energy storage) electrical appliances with medium and low power cannot drive the pumps of high-pressure cleaning machines. Therefore, in order to enable the induction motor and the inner-rotor type DC brushless motor to drive high-pressure pumps or use small-power energy storage power supplies to drive high-power and high-pressure pumps, it is necessary to add a stage of transmission gears between the motor and the pump to improve the load capacity of the motor. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a power device for a new type of cleaning machine to solve the above technical problems.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a power device for a new type of cleaning machine, including a swashplate pump and a motor. A first transmission gear is provided on the output shaft of the motor. One end of the swashplate pump is provided with a positioning shaft that is in transmission connection with the swashplate pump. A second transmission gear is provided on the positioning shaft. The first transmission gear on the motor meshes with the second transmission gear on the positioning shaft, so that the motor drives the swashplate pump through the gear transmission method.

[0005] Further, the swashplate pump includes an upper end cover, a lower end cover, and a plunger swashplate. The lower end cover is used to connect the motor and the upper end cover. The plunger swashplate is located inside the upper end cover. The first transmission gear and the second transmission gear mesh inside the lower end cover. The positioning shaft is axially inserted and matched with the plunger swashplate to form an integral body.

[0006] Further, a plurality of plungers are installed at the lower end of the upper end cover, and the plungers are connected to the inclined end face of the plunger swashplate.

[0007] Further, one end of the lower end cover is connected to the side of the motor where the output shaft is provided by means of threaded connection, and the output shaft extends into the lower end cover. The end of the lower end cover away from the motor is fixed to the upper end cover by means of threaded connection.

[0008] Further, a second transmission gear, a first deep groove ball bearing and a first oil seal are sequentially sleeved on the positioning shaft from inside to outside.

[0009] Further, a second oil seal, a second deep groove ball bearing and a first transmission gear are sequentially sleeved on the output shaft of the motor from inside to outside.

[0010] Further, the module of the first transmission gear and the second transmission gear is 1 - 1.5.

[0011] Further, the transmission ratio of the first transmission gear and the second transmission gear is 2:1.

[0012] Further, a liquid inlet pipe and a liquid outlet pipe are provided on the upper end cover.

[0013] Through the above technical solution, compared with the prior art, the present utility model has the following beneficial effects: By arranging a first transmission gear on the output shaft of the motor and the matching oil seal and deep groove ball bearing, and arranging a second transmission gear for driving the swash plate pump on one side of the swash plate pump, the first transmission gear and the second transmission gear are meshed, and the first transmission gear is a small gear with a module of 1 - 1.5, and the second transmission gear is a large gear. The transmission ratio of this set of gears is about 2:1. Through the above transmission method, the motor speed can be reduced to about 1400 r / min or 1680 r / min.

[0014] Therefore, adding a set of transmission gears between the swash plate pump and the motor can effectively increase the transmission efficiency of the motor, enable the induction motor and the inner rotor type DC brushless motor to drive a large pressure pump or enable a small power energy storage power supply to drive a large power and large pressure pump, and improve the overall load capacity of the motor.

[0027] As shown in Figures 1-5 Figure 4: A power device for a new type of cleaning machine, including a swash plate pump 1 and a motor 2. A first transmission gear 3 is provided on the output shaft of the motor 2. One end of the swash plate pump 1 is provided with a positioning shaft 4 that is in transmission connection with the swash plate pump 1. A second transmission gear 5 is provided on the positioning shaft 4. The first transmission gear 3 on the motor 2 and the second transmission gear 5 on the positioning shaft 4 are meshed with each other, so that the motor 2 drives the swash plate pump 1 by means of gear transmission.

[0028] As shown in Figures 1-5 Figure 5: The swash plate pump 1 includes an upper end cover 101, a lower end cover 102, and a plunger swash plate 103. The lower end cover 102 is used to connect the motor 2 and the upper end cover 101. The plunger swash plate 103 is located inside the upper end cover 101. The first transmission gear 3 and the second transmission gear 5 are meshed inside the lower end cover 102. The positioning shaft 4 is axially inserted and matched with the plunger swash plate 103 to form an integral body.

[0029] In this embodiment, by setting the positioning shaft 4 and making the positioning shaft 4 axially inserted and matched with the plunger swash plate 103 to form an integral body, a second transmission gear 5 is fixed on the positioning shaft 4. The second transmission gear 5 can drive the positioning shaft 4 to rotate and further drive the plunger swash plate 103 to rotate synchronously. The specific working process is as follows: First, start the motor 2. The motor 2 will drive the first transmission gear 3 fixed on its output shaft to rotate. Since the first transmission gear 3 and the second transmission gear 5 are meshed, when the first transmission gear 3 rotates, it will drive the second transmission gear 5 to rotate, so that the positioning shaft 4 fixed to the second transmission gear 5 rotates and further drives the plunger swash plate 103, so that the motor 2 and the swash plate pump 1 operate synchronously.

[0030] As shown in Figure 5 Figure 6: A plurality of plungers 6 are installed at the lower end of the upper end cover 101. The plungers 6 are connected to the inclined end face of the plunger swash plate 103. In this embodiment, the specific number of the plungers 6 is 3. Increasing the number of the plungers 6 can improve the transmission efficiency.

[0031] As shown in Figure 1 Figure 7: One end of the lower end cover 102 is connected to the side of the motor 2 where the output shaft is provided by means of threaded connection, and the output shaft extends into the lower end cover 102. The end of the lower end cover 102 away from the motor 2 is fixed to the upper end cover 101 by means of threaded connection. By providing the lower end cover 102, the gear transmission part can be protected therein to avoid damage to the transmission part caused by exposing it to the outside.

[0032] As shown in Figures 3-4 Figure 8: A first oil seal 9, a first deep groove ball bearing 10, and a first transmission gear 3 are sleeved on the output shaft of the motor 2 from inside to outside in sequence. The first oil seal 9 is arranged between the inner wall of the lower end cover 102 close to the motor 2 and the first deep groove ball bearing 10.

[0033] As shown in Figures 4-5 Figure: A second transmission gear 5, a second deep groove ball bearing 7, and a second oil seal 8 are successively sleeved on the positioning shaft 4 from inside to outside.

[0034] The module of the first transmission gear 3 is 1 - 1.5.

[0035] The transmission ratio of the first transmission gear 3 and the second transmission gear 5 is 2:1.

[0036] By arranging the first transmission gear 3, a first oil seal 9 and a first deep groove ball bearing 10 matching therewith on the output shaft of the motor 2, and arranging a second transmission gear 5 for driving the swash plate pump 1 on one side of the swash plate pump 1, and a second oil seal 7 and a second deep groove ball bearing 8 matching therewith, the first transmission gear 3 and the second transmission gear 5 are meshed. The first transmission gear 3 is a small gear with a module of 1 - 1.5, and the second transmission gear 5 is a large gear. The transmission ratio of this set of gears is about 2:1. Through the above transmission method, the motor speed can be reduced to about 1400 r / min or 1680 r / min.

[0037] In summary, by arranging the meshed first transmission gear 3 and second transmission gear 5 between the motor 2 and the swash plate pump 1 to achieve the effect of gear transmission, the technical problems of low transmission efficiency and weak load energy between the existing motor 2 and the swash plate pump 1 are solved, and an induction motor and an inner rotor type DC brushless motor can drive a large pressure pump, or a small power energy storage power supply can drive a large power and large pressure pump.

[0038] As shown in Figures 1-5 Figure: An upper end cover 101 is provided with a liquid inlet pipe 104 and a liquid outlet pipe 105. The liquid at the liquid inlet pipe 104 can be transported to the liquid outlet pipe 105 through the pump body of the swash plate pump 1.
