Detailed Description
In order to make the utility model realize that technical means, creation characteristics, achievement purpose and efficiency are easily understood and known, following embodiment combines the figure to be right the utility model discloses a detachable steel band pulley pivot structure does specifically expounds.
< example >
As shown in fig. 1, the present embodiment provides a detachable steel pulley rotating shaft structure, including: the device comprises a first bearing 1, a steel belt wheel 2, a flat key 3, a second bearing 4 and a rotating shaft 5.
The shaft 5 has a first shaft section 51 and a second shaft section 52 of unequal diameters, the first shaft section 51 having a larger diameter than the second shaft section 52. The steel belt wheel 2 is sleeved on the second shaft section 52 of the rotating shaft 5, the steel belt wheel 2 is connected with the rotating shaft 5 through the flat key 3, a wheel key groove matched with the flat key 3 is formed in the inner wall of the steel belt wheel 2, and a shaft key groove matched with the flat key 3 is formed in the second shaft section 52 of the rotating shaft 5. The steel belt wheel 2 can be a steel belt wheel provided with a single steel groove or a steel belt wheel provided with a plurality of steel grooves, and this embodiment illustrates the steel belt wheel 2 provided with two steel grooves in fig. 1.
The first bearing 1 is mounted on the first shaft section 51 of the rotating shaft 5 and contacts with a first end surface (left end surface as shown in fig. 1) of the steel belt wheel 2. The outer diameter of the first end face of the steel pulley 2 is larger than the diameter of the first shaft section 51 and smaller than the outer diameter of the first bearing 1. The second bearing 4 is mounted on the second shaft section 52 of the rotating shaft 5 in a sleeved manner and contacts with a second end surface (the right end surface as shown in fig. 1) of the steel belt wheel 2. The outer diameter of the second end face of the steel pulley 2 is smaller than the outer diameter of the second bearing 4. The first bearing 1 and the second bearing 4 both adopt ball bearings.
The working process of the detachable steel belt wheel rotating shaft structure of the embodiment is as follows:
