Abstract
The utility model discloses a vibrting spear, including the barred body motor interior with arranging the barred body in, the power output shaft's of motor front end is equipped with the bearing, still is equipped with the pivot in the place ahead of power output shaft, is fixed with the eccentric block in the pivot, the both ends of pivot are all through bearing and barred body fixed connection, and pivot and power output shaft are connected through joint -axis run between pivot and the power output shaft on same axial lead. The utility model discloses a be connected through joint -axis run between the pivot of eccentric block and the power output shaft of motor, consequently can pass to the power output shaft of motor through shaft coupling antivibration to the protection motor increases the motor life -span.
Description
Technical field
The utility model relates to building appliance, particularly a kind of vibrating head.
Background technology
When carrying out concreting component, usually needing to use vibrating head to go deep into carrying out dither in concrete, so that the cavity of reducing in concrete and gap, improving concrete fastening effect and quality.Traditional vibrating head is normally circled by the eccentric block in motor direct-drive vibrating head barred body, makes vibrating head produce vibration thus.The motor output shaft of this kind of vibrating head, owing to being directly fixedly connected with eccentric block, so eccentric block is when high speed circular motion, can causing damage to rotor, the vibrating head life-span is declined.
Utility model content
In order to overcome above-mentioned defect, the utility model provides the concrete vibration bar of length of a kind of life-span.
The utility model is achieved through the following technical solutions:
A kind of vibrating head, comprise barred body and be placed in the motor in barred body, the front end of the power output shaft of described motor is provided with bearing, also rotating shaft is provided with in the front of power output shaft, rotating shaft is fixed with eccentric block, the two ends of described rotating shaft are all fixedly connected with barred body by bearing, and rotating shaft and power output shaft, on same axial line, are connected by shaft coupling transmission between rotating shaft with power output shaft.
Described shaft coupling is paul pawl coupling.
The beneficial effects of the utility model:
Be connected by shaft coupling transmission between the rotating shaft of eccentric block of the present utility model and the power output shaft of motor, therefore can prevent from vibrating by shaft coupling the power output shaft passing to motor, thus protection motor, increase electrical machinery life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
As shown in Figure 1, the motor 2 that the utility model comprises barred body 1 and is placed in barred body 1, the front end of the power output shaft 3 of described motor 2 is provided with bearing 4, rotating shaft 5 is also provided with in the front of power output shaft 3, rotating shaft 5 is fixed with eccentric block 6, the two ends of described rotating shaft 5 are all fixedly connected with barred body 1 by bearing 4, and rotating shaft 5 and power output shaft 3, on same axial line, are in transmission connection by shaft coupling 7 between rotating shaft 4 and power output shaft 3.
Described shaft coupling 7 is paul pawl coupling.
