The utility model content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of long service life, wall sander cheap for manufacturing cost are provided.
A kind of novel wall sander that provides according to the utility model, comprise the hand-held person in charge, disk and sanding apparatus, described disk is installed in the hand-held front end of being responsible for, described sanding apparatus is installed in the disk, described disk is provided with a motor, and this motor is in transmission connection by a deceleration device and power transmission shaft and sanding apparatus.
The utility model also has following attached technical characterictic;
Be provided with an inner chamber in the described disk, described motor is installed in the disk back side by bolting, its output shaft passes the inner chamber diapire and stretches into inner chamber, described deceleration device is established in the inner chamber, comprise the big belt pulley and the small belt pulley that connect by belt transmission, wherein, small belt pulley is fixedlyed connected with motor output shaft, big belt pulley is fixedlyed connected with described power transmission shaft, and power transmission shaft is simultaneously affixed with sanding apparatus.
Described lumen openings place be provided with one can closed cavity lid, described power transmission shaft passes lid and is installed on the inner chamber diapire by bearing, power transmission shaft part in inner chamber is affixed with big belt pulley, it is affixed with sanding apparatus to expose to the inner chamber part.
Described belt is trapezoidal synchronous band, and big belt pulley and small belt pulley are trapezoidal skin synchronous pulley.
Described hand-held person in charge's rear end part is equipped with motor power gauge tap and motor speed controller.
Also be connected with hose between described hand-held person in charge's front end and the disk.
A kind of novel wall sander according to the utility model provides has following advantage with respect to prior art:
The first, in this structure, motor is installed in the disk back side, be in transmission connection by a deceleration device and power transmission shaft between itself and the sanding apparatus, deceleration device is that trapezoidal synchronous pulley group constitutes, and is not easy to skid in its deceleration transmission, and power transmission shaft is the hard axle of steel, its anti-twist intensity height, can bear very large torque, the sanding apparatus polishing torque that wall produced can not twist off it, thereby, product is not easy to damage long service life;
The second, in this structure, be in transmission connection by a deceleration device and power transmission shaft between motor and the sanding apparatus, wherein, deceleration device can very cheap price buy on market, thereby it is cheap for manufacturing cost for trapezoidal synchronous pulley group commonly used.
Description of drawings:
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structure for amplifying schematic diagram of I among Fig. 1.
The specific embodiment:
