Abstract
The utility model relates to a planetary gear speed reducing mechanism of an inflatable pump, which comprises three planetary gears, wherein both ends of a rotating shaft of each planetary gear are fixedly supported on a left clamping plate and a right clamping plate, and an output rotating shaft is connected with the right clamping plate; and the planetary gear speed reducing mechanism is characterized in that a first groove is arranged on the right clamping plate and the output rotating shaft; and balls are arranged in the first groove to enable the balls and the output shaft end part of a motor to form rolling friction fit. By providing the groove and the balls, the utility model can change the friction between the right clamping plate and the planetary gears into rolling friction, thereby greatly reducing resistance of two transmissions, improving rotational flexibility and reducing noise.
Description
Technical field
The utility model relates to gas-filled pump, specifically refers to the planetary gear reducing mechanism that is connected with the gas-filled pump motor.
Background technique
The patent No. is the gear reducer that the Chinese utility model patent of ZL200720108279.0 (notice of authorization number for CN201068957Y) discloses a kind of automobile-used gas-filled pump, input gear, output revolving shaft, housing and reduction gears mechanism that it comprises motor, is connected with machine shaft; Wherein, described reduction gears mechanism comprise internal tooth casing, with three planetary pinions of internal tooth casing engagement, above-mentioned input gear also is meshing with each other with it between three planetary pinions, three planetary rotating shaft two end supports are on the left and right clamping plate of described internal tooth casing both ends of the surface, output revolving shaft is fixed on the right clamping plate, under the drive of planetary gear reducing mechanism, slowly rotates, thus the connecting rod work of drive gas-filled pump, produce pressurized air through piston up-down, finish the inflation task.This planetary gear reducing mechanism output torque is big, power loss is few.But the rotation of right clamping plate and output revolving shaft and the friction between the planetary pinion are bigger, and rotational resistance is big, and the rotation flexibility is not good enough, and the noise of generation is big; Owing to also there is the influence of artificial assembling factor, may make the cooperation between planetary pinion and the clamping plate tightr simultaneously, like this, the problems referred to above can more obviously and be given prominence to.Reduce rotational resistance and noise, also higher except guaranteeing the installation precision for the dimension precision requirement of each component processing, the die cost height.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, and the planetary gear reducing mechanism that a kind of transmission resistance is little, rotate flexibly and reduced the gas-filled pump of noise is provided.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the planetary gear reducing mechanism of this gas-filled pump comprises internal tooth casing, three planetary pinions, planetary rotating shaft two ends are fixedly supported upon on the left and right clamping plate, and output revolving shaft connects described right clamping plate; It is characterized in that: offer first groove on described right clamping plate and the output revolving shaft, and be placed with ball in first groove, making the steel ball and the output shaft end of motor is that rolling friction cooperates.
By groove and ball are set, can change the pivoting friction between right clamping plate and the planetary pinion into rolling friction, reduce two transmission resistances greatly, improved the rotation flexibility, reduced noise.
The big phenomenon of the caused transmission resistance of mismatch error that artifact is brought during for fear of installation can also offer second shallow grooves on described right clamping plate, around first groove; Like this, install in any case, can not touch between the input gear that right clamping plate and drive planetary pinion rotate, thereby can not produce friction, the transmission resistance is littler, rotates more flexible.
In the such scheme, preferably, described first groove can be approximate cylindrical recesses, and the internal diameter of the internal diameter of first groove and described ball is suitable, to locate ball better.
Compared with prior art, the utility model is owing to offered first groove on right clamping plate and planetary mating face, and in first groove, placed ball, it is rolling friction that pivoting friction between right clamping plate and the planetary pinion is changed, reduced the transmission resistance greatly, make the rotation of right clamping plate and output revolving shaft more flexible, reduced operating noise; And the design of second shallow grooves, the phenomenon that the frictional force of then having avoided artificial alignment error to bring increases.
Description of drawings
Fig. 1 is the utility model embodiment's sectional structure schematic representation (steel ball is not installed);
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the sectional structure schematic representation (steel ball has been installed) after embodiment of the present utility model and motor are installed.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2 and shown in Figure 3, the planetary gear reducing mechanism of this gas-filled pump comprises three planetary pinions 4 that are meshed with the internal tooth casing (not shown), and the two ends of the rotating shaft 7 of planetary pinion 4 are fixedly supported upon respectively between left clamping plate 3 and the right clamping plate 2; The output shaft 10 of motor 9 connects input gear 11, and input gear 11 stretches into the centre of three planetary pinions 4 and is meshed with them.
In the present embodiment, the output revolving shaft 1 that is connected on the right clamping plate 2 is one-body molded with right clamping plate, and first groove 5 of near cylindrical is opened on right clamping plate 2 and the output revolving shaft 1; Place in first groove with the ball 8 that the internal diameter of first groove 5 is suitable, the ball in the present embodiment adopts steel ball, and making steel ball 8 is that rolling friction cooperates with output shaft 10 ends of motor; Also offer second shallow grooves 6 on the right clamping plate 2, around first groove 5.
During work, input gear 11 rotates with the rotation of the output shaft 10 of motor 9, drives the planetary pinion 4 that is engaged with and rotates, and three planetary pinions 4 rotate along the internal tooth synchromesh of internal tooth casing, through rotating shaft 7 left and right clamping plate are rotated synchronously, thereby output revolving shaft 1 is rotated.Because the setting of first groove and steel ball, friction between right clamping plate 2 and input gear and the planetary pinion is rolling friction, owing to the existence of second shallow grooves, avoided between right clamping plate and input gear and the planetary pinion simultaneously because the caused frictional force that closely cooperates that alignment error caused.This planetary gear reducing mechanism rotates flexibly, and noise is little.
