Abstract
The utility model discloses a zero back clearance type reducer which comprises a drive motor and multiple reducing gear pairs connected with the drive motor in a transmission manner, wherein each reducing gear pair comprises a master gear having a smaller diameter and a pinion having a bigger diameter; the pinion of each reducing gear pair is coaxially connected with the master gear of the adjacent reducing gear pair; and a gear band for transmission is arranged between the master gear and the pinion of each reducing gear pair. By using the gear band to realize the transmission of the master gear and the pinion of the reducing gear pair, since the gear band is a flexible part, other gears can be tightly jointed, back clearance can not be generated during transmission, and the transmission accuracy and efficiency are high.
Description
Technical field
the utility model relates to a kind of no back clearance speed reducer.
Background technique
speed reducer is that a kind of power is passed on mechanism, utilizes the velocity transducer of gear, the winding number of motor (motor) is decelerated to desired winding number, and obtain the mechanism of big torque.Mostly be directly to be connected with a joggle between driving gear and the gear at present, during transmission, output terminal fixed; Input end rotates clockwise with counterclockwise; When making input end produce rated torque+-2% moment of torsion, because gear is for being hard member, the speed reducer input end can produce a small angular displacement; This angular displacement is exactly backhaul gap, i.e. back clearance.And back clearance can reduce transmission accuracy and efficient.
The model utility content
The purpose of the utility model provides a kind of transmission does not have the back clearance speed reducer accurately
are for solving the problems of the technologies described above; The utility model adopts following technological scheme: a kind of no back clearance speed reducer; It comprises drive motor, with drive motor be in transmission connection mutually how right to reduction gear; Every pair of described reduction gear is to comprising the less master gear of diameter, the pinion that diameter is bigger; Each is connected with the right master gear same axis of the reduction gear that is adjacent the right pinion of described reduction gear, is provided with the gear band that transmission is used between the master gear of every pair of reduction gear and the pinion.
are optimized, and described gear band is processed by rubber.
further; It comprises also that the master gear that is connected with same axis and the coupling shaft of pinion rotate and is connected and is fixed on the support block on the frame, described support block comprise parallel with horizontal plane and with the cross-brace piece and the perpendicular vertical support block that is fixedly connected of cross-brace piece of the perpendicular setting in frame side.
further, the velocity ratio of master gear and pinion is 3/1～5/1.
The beneficial effect of
the utility model is: the utility model utilizes gear band to realize the transmission of the major and minor gear that reduction gear is right; Because gear band is a flexible member; Fit tightly between all the other gears, can not produce back clearance during transmission, transmission accuracy and efficient are higher.
Description of drawings
Accompanying drawing 1 is the three-dimensional figure of the utility model;
Accompanying drawing 2 is the schematic representation of the right relative position of reduction gear;
In the accompanying drawing: 1, drive motor; 2, reduction gear is right; 3, gear band; 4, support block; 21, master gear; 22, pinion; 41, cross-brace piece; 42, vertical support block;
Embodiment
Below in conjunction with embodiment shown in the drawings the technological scheme of the utility model is done following detailed description the in detail:
are as shown in Figure 1, two pairs of reduction gear that this no back clearance speed reducer comprises drive motor 1, be in transmission connection with drive motor 1 mutually to 2, gear band 3 that rubber is processed, the master gear 21 and the coupling shaft of pinion 22 that are connected with same axis rotate and be connected and be fixed on the support block 4 on the frame.
are as shown in Figure 2; Every pair of described reduction gear comprises the less master gear of diameter 21, the pinion 22 that diameter is bigger to 2; Master gear 21 is 4:1 with the velocity ratio of pinion 22; Each is connected 2 master gear 21 same axis 2 pinion 22 and the reduction gear that is adjacent described reduction gear, is provided with the gear band 3 that transmission is used between the master gear 21 of every pair of reduction gear 2 and the pinion 22.
described support block 4 comprise parallel with horizontal plane and with the cross-brace piece 41 and the cross-brace piece 41 perpendicular vertical support blocks 42 that are fixedly connected of the perpendicular setting in frame side.
the foregoing description is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
