Abstract

The invention discloses a belt wheel, and particularly relates to a tensioning belt wheel. The tensioning belt wheel comprises a motor, a tensioning sleeve and a belt wheel body. The connecting face of the belt wheel body and the tensioning sleeve is conical. Bolt assemblies comprise studs and anti-loosening nuts. One end of each stud is fixed to the tensioning sleeve, the other end of each stud penetrates out of the belt wheel body, the section of the other end of each stud is hexagonal, and threads of the studs are arranged on the parts, penetrating out of the belt wheel body, of the studs. The anti-loosening nuts comprise threaded sleeves and nuts, the threaded sleeves penetrate the other ends of the studs and are in threaded connection to threaded sections, inner holes matched with the other ends of the studs in shape are formed in the nuts, the other ends of the studs are connected into the nuts in a sleeved manner, and the nuts are buckled and connected to the threaded sleeves. The defect that a belt wheel in the prior art is prone to looseness is overcome, and the tensioning belt wheel can prevent connecting loosening.

Description

technical field [0001] The invention relates to a pulley, in particular to a tension pulley. Background technique [0002] The motor pulleys used in the market are all integral structures, which are fixed pulleys. Other auxiliary tools must be used for disassembly and maintenance, which is inconvenient. It is easy to damage the motor output shaft during disassembly and assembly, causing the motor to be scrapped. [0003] In order to solve the above-mentioned technical problems, Chinese patent CN201549973 discloses a motor pulley, which is composed of a motor and a pulley, and is characterized in that a tension sleeve is fixed on the output shaft of the motor, and the pulley and the tension sleeve are integrally connected by bolts. The connection surface between the pulley and the tension sleeve is tapered. [0004] The above-mentioned patent has the following technical defects: bolts are used to fix the pulley and the tension sleeve, but in the long-term working process, th...
