Description
Technical Field
The utility model relates to a reduction gear technical field especially relates to an electric tricycle reduction gear shell.
Background
The tricycle speed reducer is a motor structure with a speed reduction conversion device assembled and connected outside a motor.
The motor shell is fixedly connected with the speed reduction converter through screw holes arranged around the driving end, and the driving shaft moves after the converter is connected, so that the common shell cannot be fully attached to the surface of the motor shell to be tightly fixed during fixed connection, the side surface of the common shell is positioned outside the shell and is easy to turn over and offset, the rotating angle is matched when the driving shaft is influenced to be converted, gears are easy to wear during long-time work, and the service life of the speed reducer is shortened.
Therefore, an electric tricycle reducer shell tightly mounted on a motor driving shaft is needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that general shell can not fully laminate motor housing surface during fixed connection, and pivoted angle agrees with when influencing the driving shaft and changing, and the gear that wears out easily of long-time work reduces the reduction gear life-span.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides an electric tricycle reduction gear shell, includes the shell face, fixedly connected with drive shaft hole is run through at shell face middle part, drive shaft hole outer wall is provided with the middle part sealing face, the middle part sealing face is kept away from two outer fixed orificess of drive shaft hole fixedly connected with, the middle part sealing face is close to the drive shaft hole outside and is provided with three interior fixed orifices.
Through above-mentioned technical scheme, set up the sealed face in middle part, the reduction gear stable connection motor of being convenient for reduces the gap between the two, prevents that the outer wall dust from getting into inside the reduction gear, influences the performance and the life of reduction gear, through adopting two outer fixed orificess and three internal fixation hole, is convenient for fix ellipse circular reduction gear housing, prevents that the reduction gear housing outside from connecting inseparably, and middle part drive shaft and gear engagement angle take place to deflect, and the gear is easy wearing and tearing.
The utility model discloses further set up to, the shell face is a plurality of fixed connection screws of outer wall fixedly connected with all around, the motor is connected to the fixed connection screw.
Through above-mentioned technical scheme, set up the fixed connection screw, the shell of drive end one side of shell outside fixed connection motor of being convenient for, it is even inseparable through the accurate fixed shell of a plurality of fixed connection screws.
The utility model discloses further set up to, the shell face is close to internal fixation hole outer wall upper surface and is provided with the arc contact surface.
Through above-mentioned technical scheme, set up the arc contact surface, can continue to provide the arc contact surface and laminate the drive article after dismantling the reduction gear, improve the commonality of shell face.
The utility model discloses further set up to, arc contact surface and middle part sealing surface material adopt alloy steel.
Through above-mentioned technical scheme, adopt alloy steel material, in order to improve the wearability and the antirust property of contact surface, avoid the surface corrosion to connect imprecisely, adopt steel non-deformable, indeformable can protect motor drive and reduction gear connection structure.
The utility model has the advantages as follows:
1. the utility model discloses a sealing face in the middle part sets up, is convenient for the reduction gear stable connection motor, reduces the gap between the two, prevents that the outer wall dust from getting into the reduction gear inside, influences the performance and the life of reduction gear, through adopting two outer fixed orificess and three internal fixation hole, is convenient for fix oval-shaped reduction gear shell, prevents that the connection is not inseparable outside the reduction gear shell, and middle part drive shaft and gear engagement angle take place to deflect, and the gear is easy to wear;
2. the utility model discloses a setting up the arc contact surface, can continuing to provide arc contact surface laminating drive article after dismantling the reduction gear, improve the commonality of shell face, adopt alloy steel material, in order to improve the wearability and the rust resistance of contact surface, avoid surface corrosion to connect imprecisely, adopt steel non-deformable, indeformable can protect motor drive and retarder connection structure.
