Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses emery wheel drive belt centre-to-centre spacing adjusting device installs the last plane at bistrique seat to staff 05 is centre of rotation C, and the center B of motor shaft moves on the circumference that the radius is BC, and is epaxial all to have offset at the level and the vertical direction for bistrique center A, thereby realizes the adjustment of the distance between AB (being belt pulley centre-to-centre spacing P).
The device for adjusting the center distance P of the belt pulley mainly comprises a grinding head seat 01, two supports 03, two set screws 04, a small shaft 05, two set screws 06, two set spherical washer assemblies 07, a motor base plate 08, a motor 09 and an adjusting screw 10.
Preferably, the two brackets 03 are respectively arranged on the upper plane of the grinding head base 01 and distributed on two sides of the motor base plate 08, the sliding plate 02 is arranged on the grinding head base 01, the small shaft 05 sequentially penetrates through the holes of the brackets 03 and the hole on one side of the motor base plate 08, and the small shaft 05 and the motor base plate 08 are fastened into a whole by the two set screws 04; two fixing screws 06 and two sets of spherical washer assemblies 07 pass through a kidney-shaped hole of the motor base plate 08 and are connected with a screw hole of the grinding head seat 01; the adjusting screw 10 is connected with a screw hole of the motor bottom plate 08; the motor 09 is fixedly arranged on the motor base plate 08; the driving pulley 12 is connected to the main shaft of the motor 09 through the expansion sleeve 11.
