技术领域technical field
本实用新型属于电动机技术领域，尤其涉及一种适用于大外径法兰轴的电机端盖。The utility model belongs to the technical field of motors, in particular to a motor end cover suitable for a flange shaft with a large outer diameter.
背景技术Background technique
在电机的装配过程中，滑动轴承的轴承座与电机端盖配合连接，电机端盖上的安装孔就必须穿过电机法兰轴上的法兰，为保证转轴同心，滑动轴承的轴承座与端盖上的安装孔尺寸也必须相适配。有时因生产设计需要，电机的法兰轴尺寸较大，其法兰轴上的法兰外径就会大于电机端盖上的安装孔，导致电机端盖装配受阻，无法顺利完成电机的装配。虽然可以通过换用更大型号的滑动轴承配合更大安装孔的端盖来解决此问题，但由于滑动轴承的尺寸变化，会引起电机其他部件的连锁性匹配问题，生产设计也随之需要重新制定，导致成本大幅增加，还会给电机的运行带来不稳定性影响。因此具有大外径法兰轴的电机与滑动轴承存在较大的选型适配困难问题，给电机的生产带来极大不便。During the assembly process of the motor, the bearing seat of the sliding bearing is connected with the motor end cover, and the mounting hole on the motor end cover must pass through the flange on the motor flange shaft. In order to ensure the concentricity of the rotating shaft, the bearing seat of the sliding bearing and the The mounting hole size on the end cap must also match. Sometimes due to production design requirements, the size of the flange shaft of the motor is large, and the outer diameter of the flange on the flange shaft will be larger than the mounting hole on the motor end cover, which will hinder the assembly of the motor end cover and fail to complete the assembly of the motor smoothly. Although this problem can be solved by replacing the sliding bearing with a larger size and the end cover with a larger mounting hole, due to the size change of the sliding bearing, it will cause interlocking matching problems with other parts of the motor, and the production design will also need to be redesigned. The formulation will lead to a substantial increase in cost, and will also bring instability to the operation of the motor. Therefore, the motor and the sliding bearing having a flange shaft with a large outer diameter have great difficulty in selection and adaptation, which brings great inconvenience to the production of the motor.
实用新型内容Utility model content
本实用新型的目的是提供一种在不改变滑动轴承尺寸的同时，能够解决大外径法兰轴的电机端盖适配困难的问题，且安装快捷方便、成本低廉的适用大外径法兰轴的电机端盖。The purpose of this utility model is to provide a large outer diameter flange that can solve the problem of difficult adaptation of the motor end cover of the large outer diameter flange shaft without changing the size of the sliding bearing, and is fast, convenient and low in cost. Shaft motor cover.
为实现本实用新型的目的所采取的技术方案是：该电机端盖采用两瓣对合式结构，其电机端盖沿水平中心线分为上端盖和下端盖，在上、下端盖结合面的一侧分别设置有上、下连接搭子，连接搭子上分别设有穿销孔和螺孔，上、下端盖通过连接搭子上的螺栓和销子连为一体构成整圆端盖。The technical solution adopted to realize the purpose of this utility model is: the motor end cover adopts a two-lobed structure, and its motor end cover is divided into an upper end cover and a lower end cover along the horizontal center line, and one side of the joint surface of the upper and lower end covers The upper and lower connecting straps are respectively provided on the side, and the connecting straps are respectively provided with pin holes and screw holes, and the upper and lower end covers are connected as a whole through the bolts and pins on the connecting straps to form a round end cover.
按照上述方案制成的适用于大外径法兰轴的电机端盖，通过将端盖改进成两瓣对合式结构，使得上、下端盖可以分开安装，在不改变滑动轴承尺寸的同时，解决了大外径法兰轴的电机端盖适配困难的问题，且安装快捷方便、成本低廉。According to the above scheme, the motor end cover suitable for the flange shaft with large outer diameter is improved into a two-lobed structure, so that the upper and lower end covers can be installed separately, and the size of the sliding bearing is not changed. The problem of difficult adaptation of the motor end cover of the flange shaft with a large outer diameter is solved, and the installation is quick, convenient and low in cost.

具体实施方式detailed description
参看图1、图2，本实用新型的一种适用于大外径法兰轴的电机端盖。该电机端盖采用两瓣对合式结构，其电机端盖沿水平中心线分为上端盖1和下端盖4，在上、下端盖结合面的一侧分别设置有上、下连接搭子5，连接搭子5上分别设有穿销孔6和螺孔7，上、下端盖通过连接搭子上的螺栓2和销子3连为一体构成整圆端盖。Referring to Fig. 1 and Fig. 2, a motor end cover suitable for a flange shaft with a large outer diameter of the utility model. The motor end cover adopts a two-lobed structure, and its motor end cover is divided into an upper end cover 1 and a lower end cover 4 along the horizontal centerline, and upper and lower connecting straps 5 are respectively arranged on one side of the joint surface of the upper and lower end covers. The connecting strap 5 is respectively provided with a pin hole 6 and a screw hole 7, and the upper and lower end covers are connected by the bolt 2 and the pin 3 on the connecting strap to form a full circle end cover.
当装配具有大外径法兰轴的电机时，将上端盖1和下端盖4分别置于法兰轴8的两端，通过上、下连接搭子5上的穿销孔6和螺孔7使用螺栓2和销子3将上端盖1和下端盖4固定连接对合后构成整圆端盖，电机端盖的两侧分别与滑动轴承和电机外壳配合连接（图中未示）。该端盖采用分瓣式设计，上、下端盖可以分开安装，安装孔9可以依据法兰轴8的法兰8-1外径大小任意调节，同时保证安装孔9与滑动轴承的轴承座相适配，使法兰轴的外径尺寸不再受到安装孔9限定的影响，在不改变滑动轴承尺寸的同时，解决了大外径法兰轴的电机端盖适配困难的问题，且安装快捷方便、成本低廉。When assembling a motor with a flange shaft with a large outer diameter, place the upper end cover 1 and the lower end cover 4 on both ends of the flange shaft 8 respectively, and connect the pin hole 6 and the screw hole 7 on the upper and lower connection straps 5 Bolts 2 and pins 3 are used to fix and connect the upper end cover 1 and the lower end cover 4 to form a round end cover, and the two sides of the motor end cover are respectively connected with sliding bearings and motor housings (not shown in the figure). The end cover adopts a split design, the upper and lower end covers can be installed separately, the installation hole 9 can be adjusted arbitrarily according to the outer diameter of the flange 8-1 of the flange shaft 8, and at the same time ensure that the installation hole 9 is consistent with the bearing seat of the sliding bearing Adaptation, so that the outer diameter of the flange shaft is no longer affected by the limitation of the installation hole 9, while not changing the size of the sliding bearing, it solves the problem of difficult adaptation of the motor end cover of the flange shaft with a large outer diameter, and the installation Fast, convenient and low cost.
