Description

减速机及转轴Reducer and shaft

技术领域technical field

本新型是有关一种减速机及转轴,且尤其是有关于一种可防止减速机的固定环自转轴上脱落的减速机及转轴。The new model relates to a reducer and a rotating shaft, and particularly relates to a reducer and a rotating shaft which can prevent the fixing ring of the reducer from falling off from the rotating shaft.

背景技术Background technique

提升机构输出扭矩的方式有很多种,其中,增加输入动力源是一种较直接的方式,例如:更换高功率的马达等等,然而,增加输入动力源可能会造成原来传动结构的强度无法承受改变而减少其使用寿命,虽然可以更换传动结构的材质或规格等来应对,但成本也将相对提高,且增加输入动力源同时意味着能量消耗的提高。There are many ways to output torque of the lifting mechanism. Among them, increasing the input power source is a more direct way, such as replacing a high-power motor, etc. However, increasing the input power source may cause the strength of the original transmission structure to be unbearable. Changes to reduce its service life, although the material or specifications of the transmission structure can be replaced, the cost will also be relatively increased, and increasing the input power source will also mean an increase in energy consumption.

而在不改变输入动力源的情况下,改变输入端与输出端之间扭矩传动的比例成为一种实用的方式,例如:缩小输入端轮径、增加输出端轮径等等,在结构强度容许范围内,使用者可以根据需求更换不同齿轮比的传动结构来达到欲提升的输出扭矩。In the case of not changing the input power source, changing the ratio of torque transmission between the input end and the output end has become a practical way, for example: reducing the diameter of the input end wheel, increasing the output end wheel diameter, etc., if the structural strength allows Within the range, users can replace the transmission structure with different gear ratios according to their needs to achieve the desired output torque.

据此,各式减速机被开发出来以满足此类需求。减速机为一种通过许多齿轮互相搭配的精密机构,因应不同的输入源与输出机构也衍生出不同的配置,包含了齿轮减速机、蜗轮蜗杆减速机、行星式减速机、立式减速机及卧式减速机等等,而各种应用的结构如今都已进行模块化设计,使用者可评估输入动力源、输出结构等实际运用状况以选择最适合的减速机类型及规格,毋须再自行计算结构强度或浪费时间组装零件,因而大幅提升使用的便利性。Accordingly, various reducers have been developed to meet such needs. The reducer is a precision mechanism that is matched with many gears. According to different input sources and output mechanisms, different configurations are also derived, including gear reducers, worm gear reducers, planetary reducers, vertical reducers and Horizontal reducer, etc., and the structure of various applications has now been modularized. Users can evaluate the actual application conditions such as input power source and output structure to select the most suitable type and specification of reducer, no need to calculate by themselves. Structural strength or waste of time assembling parts, thus greatly improving ease of use.

然而,随着各种减速机运用机会的增加,相关业者必须提升减速机的产能以因应市场需求,同时保持良好的质量。一般而言,减速机会配置固定环,其目的在使马达主轴与减速机结合时迫紧主轴,达到两者的紧密配置。然而,当组装厂向减速机厂商购入减速机并进行组装时,需先将固定环旋松以利马达主轴套入减速机的转轴内,此种作法容易使固定环脱落遗失。However, with the increase in the application opportunities of various reducers, the relevant industry must increase the production capacity of the reducers to meet the market demand while maintaining good quality. Generally speaking, the reducer is equipped with a fixing ring, the purpose of which is to tighten the main shaft when the motor main shaft and the reducer are combined to achieve a close arrangement of the two. However, when the assembly factory purchases the reducer from the reducer manufacturer and assembles it, the fixing ring needs to be loosened so that the motor main shaft can be inserted into the rotating shaft of the reducer. This method is easy to cause the fixing ring to fall off and lose.

有鉴于此,如何防止减速机的固定环脱落遗失,遂成为相关业者努力研究的目标。In view of this, how to prevent the fixing ring of the reducer from falling off and losing has become the goal of the relevant industry.
