Embodiment Construction

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0034] In describing the present invention, it should be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", " The orientation or positional relation...

Abstract

The invention provides a lathe spindle. The lathe spindle comprises a spindle core and a body sleeved on the spindle core, a belt wheel assembly used for driving the spindle core to rotate is arranged on the spindle core in a sleeved mode, the belt wheel assembly comprises a belt wheel arranged on the spindle core in a sleeved mode and a driving ring arranged on the spindle core in a sleeving mode and fixedly connected with the belt wheel and used for driving the spindle core to rotate, a first damping part is arranged between the belt wheel and the spindle core in a sleeved mode, and a second damping part is arranged at the fixed connection part between the belt wheel and the driving ring. According to the lathe spindle, the first damping part is arranged between the belt wheel and the spindle core in a sleeved mode, the second damping part is arranged at the joint between the driving ring and the belt wheel, the vibration generated by the belt wheel is greatly weakened by the first damping part and the second damping part, so that the spindle core can be prevented from being in radial linkage with the sleeving position of the belt wheel in the rotating process of the spindle core, the spindle core is prevented from being in radial linkage with the sleeving position of the driving ring in the rotating process of the spindle core, the stability of the spindle core in the rotating process is ensured, and the precision of a machined part machined by the lathe spindle is higher.

Description

technical field [0001] The invention belongs to the technical field of lathe processing, and more specifically relates to a lathe spindle. Background technique [0002] The lathe spindle refers to the axis on the lathe that drives the workpiece or tool to rotate. The main shaft part is usually composed of the main shaft, bearings and transmission parts (gears or pulleys). In the machine, it is mainly used to support transmission parts such as gears and pulleys, transmit motion and torque, such as lathe spindles, and some are used to clamp workpieces, such as mandrels. [0003] At present, the transmission parts of lathe spindles in the industry mostly adopt the transmission mode of belt and pulley. [0004] Due to the poor stability of the belt in the transmission process, it is prone to vibration, and the vibration of the belt is transmitted to the shaft core, resulting in a large radial series movement of the shaft core during the rotation process, resulting in vibration...
