Embodiment 1

[0033] Embodiment one, such as Figure 1 to Figure 3 As shown, an assembled pulley assembly includes a pulley body made of plastic material and a connecting sleeve 1 made of rigid material, the connecting sleeve 1 is used for interference fit connection with a steel pipe, and the pulley body It includes a belt installation part 3 for installing the belt and a connection sleeve installation part 2 for connecting with the connection sleeve 1 . The connection sleeve 1 is axially sleeved on the connection sleeve installation part 2, and the outer peripheral side of the connection sleeve installation part 2 is provided with a limiting groove communicating with one end in the axial direction, and the inner peripheral side of the connection sleeve 1 is provided with The limiting protrusion 1-1 is assembled and connected with the limiting groove. The pulley body also includes a steel pipe press-fitting part, the first axial end of the steel pipe press-fitting part is connected to the...

Embodiment 2

[0046] Embodiment two, such as Figure 4 with Figure 5 As shown, the difference from the first embodiment is that the belt installation part 3 can be an O-shaped belt installation part, which is used for assembling with the O-shaped belt.

Embodiment 3

[0047] Embodiment three, such as Image 6 with Figure 7 As shown, the difference from Embodiment 1 is that the belt installation part 3 may be a timing belt installation part for assembling with the timing belt.

Abstract

The invention relates to the technical field of logistics transportation design, in particular to an assembled belt wheel component. The assembled belt wheel component comprises a belt wheel body made of a plastic material and a connecting sleeve made of a rigid material; the connecting sleeve is used for being connected with a steel pipe in an interference fit mode; the belt wheel body comprises a belt body mounting part used for mounting a belt body and a connecting sleeve mounting part used for being connected with the connecting sleeve; the connecting sleeve is axially mounted on the connecting sleeve mounting part in a sleeving mode; a limiting groove communicating with one axial end of the connecting sleeve mounting part is formed in the outer peripheral side of the connecting sleeve mounting part; and a limiting protrusion connected with the limiting groove in an assembled mode is arranged on the inner peripheral side of the connecting sleeve. According to the assembled belt wheel component, the assembled belt wheel component is divided into the connecting sleeve and the belt wheel body, the belt wheel body is integrally made of a plastic material, and the connecting sleeve is made of a material with high strength and hardness and can be stably connected with a steel pipe for a long time in an interference fit mode; and therefore, the phenomenon that the multi-wedge belt wheel component is loosened from the steel pipe after being used for a long time can be avoided.

Description

technical field [0001] The invention relates to the technical field of logistics transportation design, in particular to an assembled pulley assembly. Background technique [0002] Pulleys have been widely used in the transmission of various mechanical equipment in automobiles, agricultural machinery and light textile industries due to the advantages of large transmission power, small vibration, and stable operation. However, most of the existing pulley components are made of one-piece plastic material, which is connected with the steel pipe through interference fit. The pulley component of this structure will be damaged due to the characteristics of the plastic material after special working conditions or long-term use. As a result, the connection effect with the steel pipe becomes poor, until it will loosen with the steel pipe, so that the roller will fail completely. [0003] For example, the utility model with the application number CN201721437105.9 discloses a new type...
