Description
Technical field
The utility model relates to a kind of belt gear, particularly a kind of belt gear of carbon brush motor.
Background technique
The carbon brush motor is a kind of comparatively traditional motor, utilizes its inner carbon brush to contact with exchanger and makes its inner coil electricity.Belt pulley is all adopted in the transmission of itself and external component, being connected between traditional belt pulley and its motor shaft need be implemented to connect by bearing pin or other contiguous block, inconvenience not only is installed, and for the precision of installing certain requirement is arranged, if the precision of installing is not enough, then in running, belt pulley very easily gets loose with motor shaft.
Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of belt gear of easy for installation, the carbon brush motor that is connected firmly.
For realizing technique scheme, the utility model provides following technological scheme: a kind of carbon
The belt gear of brush motor, include wheel body, the outer circumferential face of wheel body is provided with some for belt connecting groove around the home, it is characterized in that: an axial side of described wheel body is provided with the motor shaft fixing body, axially offer the motor shaft mounting hole along the motor shaft fixing body in this motor shaft fixing body, the motor shaft fixing body is provided with at least one installation slot that extends in the motor shaft mounting hole with respect to the end face that is connected the other end of an end with wheel body, and the inwall of motor shaft mounting hole is provided with netted connection bump.
Adopt technique scheme, be used for implementing to be connected by motor shaft fixing body and motor with the wheel body of belt enforcement transmission, connection and transmission are comparatively convenient like this; The motor shaft fixing body is provided with the motor shaft mounting hole that is connected with the motor shaft of motor, and the motor shaft mounting hole is provided with the installation slot, also be provided with the cutting adaptive with this installation slot on the motor shaft accordingly, after arranging like this, after in motor shaft is inserted in the motor shaft mounting hole, motor shaft circumferentially obtain the location, so motor shaft when rotation, will inevitably drive the rotation of motor shaft fixing body and wheel body, impel belt to obtain transmission; For make between motor shaft and the motor shaft fixing body be connected more compact, the inwall of motor shaft mounting hole is provided with netted connection bump, can be more stable and compact after can making motor shaft be inserted in the motor shaft mounting hole like this, prevent motor shaft in running, motor shaft fixing body and motor shaft come off.
The utility model further is set to: the cross section that slot is installed is " V " font.
Adopt technique scheme, arrange like this to make and being connected between slot and the motor shaft is installed locatees more compact.
The utility model further is set to: the diameter of motor shaft fixing body is greater than the diameter of wheel body, is connected by the conical surface between motor shaft fixing body and the wheel body.
Adopt technique scheme, setting can increase the force intensity that is subjected to of motor shaft fixing body like this, can prevent the situation that the motor shaft scaffold fracture takes place and damages.
Below in conjunction with accompanying drawing the utility model is further described.
