Description

齿式联轴器防脱齿装置 Gear coupling anti-gearing device

技术领域 technical field

本实用新型涉及一种机械设备上使用的装置,特别是涉及一种轧钢设备上使用的齿式联轴器防脱齿装置。The utility model relates to a device used on mechanical equipment, in particular to a tooth-type shaft coupling anti-gearing device used on steel rolling equipment.

背景技术 Background technique

在轧钢生产中,为防止轧制过程中传动转矩异常,损坏机械及电气设备。通常在电机输出端与齿轮箱或减速机输入端的连接,都采用齿式安全销联轴器。当转矩超出电机或齿轮箱、减速机等设备的安全传动力矩时,安全销发生断裂,电机与机械传动部分脱离,从而保护相关设备安全。但当安全销断后,由于惯性的原因,两端半联轴器将在短时间内保持各自运转。In steel rolling production, in order to prevent abnormal transmission torque during the rolling process, damage to mechanical and electrical equipment. Usually, gear safety pin couplings are used to connect the output end of the motor with the input end of the gearbox or reducer. When the torque exceeds the safe transmission torque of the motor, gearbox, reducer and other equipment, the safety pin breaks, and the motor is separated from the mechanical transmission part, thereby protecting the safety of related equipment. But when the safety pin is broken, due to the inertia, the half-couplings at both ends will keep running separately in a short time.

目前,由于对齿式安全销联轴器的内齿圈,在轴向脱齿方向除正常情况下靠安全销连接固定外,没其它装置进行固定。因此,当安全销发生断裂后,两半联轴器内齿圈将发生脱齿。由于一般的轧钢所采用的齿式联轴器较大,当发生联轴器内外脱齿后,给恢复带来较大困难,严重影响生产。At present, due to the inner ring gear of the gear-type safety pin coupling, there is no other device for fixing in the axial de-gearing direction except that it is connected and fixed by the safety pin under normal circumstances. Therefore, when the safety pin breaks, the inner ring gears of the two halves of the coupling will lose their teeth. Due to the large gear couplings used in general steel rolling, when the internal and external teeth of the couplings are detached, it will bring great difficulties to the recovery and seriously affect the production.

具体实施方式 Detailed ways

下面结合附图对本实用新型进一步说明。Below in conjunction with accompanying drawing, the utility model is further described.

如图1和图2所示,齿式联轴器防脱齿装置,包括联轴器,联轴器的主动端6和从动端7分别设置有相配合的凸缘8、9,在联轴器6的凸缘8、9上设置有止退件2。当转矩超出电机或齿轮箱、减速机等设备的安全传动力矩时,安全销发生断裂,安全销断后,由于惯性的原因,联轴器的主动端6和从动端7将在短时间内保持各自运转,由于有止退件2的限位作用,防止了联轴器的主动端6和从动端7的凸缘8、9分离过大,从而有效阻止了内齿圈的脱齿。As shown in Fig. 1 and Fig. 2, the anti-off gear device of the gear coupling includes a coupling, and the driving end 6 and the driven end 7 of the coupling are respectively provided with matching flanges 8 and 9. Backstops 2 are provided on the flanges 8 and 9 of the hub 6 . When the torque exceeds the safe transmission torque of the motor, gearbox, reducer and other equipment, the safety pin breaks, and after the safety pin breaks, due to inertia, the driving end 6 and the driven end 7 of the coupling will break in a short time To keep running separately, due to the limit function of the stopper 2, the flanges 8, 9 of the driving end 6 and the driven end 7 of the coupling are prevented from being separated too much, thereby effectively preventing the toothing of the inner ring gear.

止退件2包括固定端3、连接段4和止退端5,固定端3和止退端5分别与连接段4的两端连接,形成凹型结构,凹型结构分别与凸缘8、9的圆周面和两端面相配合。这种凹型结构可以刚好将联轴器6的凸缘1限位。The backstop 2 includes a fixed end 3, a connecting section 4 and a backstop 5. The fixed end 3 and the backstop 5 are respectively connected to the two ends of the connecting section 4 to form a concave structure. The concave structure is connected to the flanges 8 and 9 respectively The circumferential surface matches the two end surfaces. This concave structure can just limit the flange 1 of the shaft coupling 6 .

止退件2的固定端3固定在联轴器6凸缘8、9的一端。止退件2的固定端3可以固定在联轴器主动端6的凸缘上,也可以固定在从动端7的凸缘上。The fixed end 3 of the stop member 2 is fixed on one end of the flanges 8 and 9 of the shaft coupling 6 . The fixed end 3 of the backstop 2 can be fixed on the flange of the driving end 6 of the shaft coupling, and can also be fixed on the flange of the driven end 7 .

止退件2的止退端5与凸缘的端面留有间隙;止退件2的连接段4与凸缘8、9的圆周面留有间隙。这种间隙的作用是在安全销断裂之后重新安装安全销的时候,可以方便的转动联轴器在止退端5一边的凸缘,调整凸缘8、9的位置关系,能更顺利地安装安全销。There is a gap between the backstop end 5 of the backstop 2 and the end surface of the flange; there is a gap between the connecting section 4 of the backstop 2 and the circumferential surfaces of the flanges 8 and 9 . The function of this gap is that when the safety pin is reinstalled after the safety pin is broken, the flange on the side of the stop end 5 of the coupling can be rotated conveniently, and the positional relationship between the flanges 8 and 9 can be adjusted to facilitate the installation. safety pin.

所述止退件2的固定板3、连接段4和止退端5通过焊接连接固定。由于这种止退件2的精度要求不高,如果用正块材料进行加工,形成一个整体的部件,对材料的浪费较大,如果对固定板3、连接段4和止退端5分别加工,然后焊接成型,能有效节约材料。The fixing plate 3, the connecting section 4 and the backstopping end 5 of the backstopping member 2 are fixed by welding. Since the precision requirement of this backstop 2 is not high, if the positive block material is used for processing to form an integral part, the waste of material is relatively large. If the fixed plate 3, the connecting section 4 and the backstop 5 are processed separately , and then welded and formed, which can effectively save materials.

止退件2的材料为A3钢。这种材料价格比较低廉,能够有效节约成本,由于止退件2采用相对于联轴器6材料较软的A3钢,在设备发生故障时,首先会破坏止退件2,而不会损坏联轴器6。The material of the backstop 2 is A3 steel. This kind of material is relatively cheap and can effectively save costs. Since the backstop 2 is made of A3 steel which is softer than the material of the coupling 6, when the equipment fails, the backstop 2 will be destroyed first without damaging the coupling. Shaft device 6.
