FIELD: process engineering.
SUBSTANCE: invention relates to production of construction materials and may be used for producing binder-base mixer in-situ. Concrete mixer drive comprises motor coupled with pulleys and enclosed housings. Housing is made up of top and bottom parts. Bottom part features a rectangle shape, one of short sides accommodating circular segment. Opening for pulley axle to pass through is arranged on the side of said circular segment at said bottom part. Air intake openings and motor fasteners are arranged on the side of second short side. Top part shape represents conjugation of arc of two circles. Note here that smaller-radius arc is located on the side of motor, while its center is located inside housing. Larger-radius arc is located on pulley side and its center is located outside the housing. Opening to accommodate connector assembly is arranged on top part and, at least, one opening is made on upper surface of housing top part, nearby motor.
EFFECT: higher efficiency of motor, longer life.
