Problems solved by technology

[0002] At present, the connection between the main shaft and the pulley in the impact sand making machine or vertical impact crusher is generally connected by a key or a tension sleeve. Since the motor power of this machine is relatively large, the main shaft must not only bear the torque, but also bear the diameter of the belt. The bending moment generated by the axial force accelerates the loss of the main shaft and produces dislocation phenomena. Generally, in order to meet the strength requirements, a thicker main shaft is often used in the design, but this increases the cost.

Embodiment Construction

[0008] Such as figure 1 As shown, it is a structural schematic diagram of the pulley unloading device of the present invention. First of all, the difference between the pulley 10 of the present invention and the existing pulley is that it has at least two axial bores 14, 15 that are coaxial but have different inner diameters, and the end near the bearing seat 3 has a larger inner diameter. The axial inner hole 15 of the shaft, the other end is sleeved on the main shaft 9 through the key 11 or the tension sleeve, and the pressure plate 12 is pressed outside the key 11, and the pressure plate 12 is fastened on the pulley 10 with bolts 13, and the pulley is unloaded. The unloading sleeve 4 of the device is empty on the main shaft 9, one end of the unloading sleeve 4 is fixed on the bearing seat 3, and the other end is located in the axial inner hole 15 and connected with the pulley 10 through the bearing 6.

Abstract

The present invention relates to a band wheel unloading device for impact sand-making machine. It can reduce, even prevent main shaft from producing bending moment by band wheel, so that it can further reduce cost. The described band wheel at least has two coaxial axial inner holes which are different in inner diameter in which one end close to bearing seat is an axial inner hole whose inner diameter is larger, another end is cover-mounted on the main shaft by means of tight fit. The described band wheel unloading device includes unloading sleeve, said unloading sleeve is cover-mounted on main shaft, one end of said unloading sleeve is fixed on the bearing seat, its another end is positioned in the axial inner hole whose inner diameter is larger and is connected with said band wheel by means of bearing.

Description

technical field [0001] The invention relates to an impact sand making machine shaft, in particular to a pulley unloading device applied to the impact sand making machine. Background technique [0002] At present, the connection between the main shaft and the pulley in the impact sand making machine or vertical impact crusher is generally connected by a key or a tension sleeve. Since the motor power of this machine is relatively large, the main shaft must not only bear the torque, but also bear the diameter of the belt. The bending moment generated by the axial force accelerates the loss of the main shaft and produces dislocation phenomena. Generally, in order to meet the strength requirements, a thicker main shaft is often used in the design, but this increases the cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pulley unloading device applied to an impact sand making machine, which can reduce or even avo...
