Abstract
The utility model relates to a coupler safety overload protective device, which is mainly applied to the connecting part of the main drive field of rolling mill equipment. An input shaft and an output shaft are respectively connected with an input shaft flange plate and an output shaft flange plate, the input shaft flange plate and the output shaft flange plate are connected through a slotting bolt, the slotting slot is provided with a bushing, the input shaft flange plate and the output shaft flange plate are externally provided with a gland, a limit device is arranged in the output shaft flange pale and between the input shaft flange plate and the output shaft flange plate, the limit device is that two sides of a bearing spacer bush is provided with a bearing, the bearing space bush is provided with a limit ring slot, and the ring slot is internally provided with a limit screw. When the utility model is overload, the slotting bole is broken, the power transmission is cut off, the input shaft flange plate can stably idle in the output shaft flange plate, and can not fall to throw out to hurt the peripheral personnel and equipment, after falling in the gland, the broken bolt can not be thrown out along the rotation of the input shaft flange plate, is convenient to clean, can furthest eliminate safety hazards, the bolt which is broken and deformed and is clamped on the flange plate can be taken out along with the bushing, the replacement is convenient and fast, and the shutdown maintenance time can be shortened.
Description
Technical field
The utility model relates to mechanical transmission fields, particularly the safe overload protection arrangement that uses on the milling equipment main transmission coupling.
Background technique
As shown in Figure 2; existing coupling overload protection arrangement is made up of input shaft 1, input shaft flange plate 2, bolt 3 (fluting bolt), nut 4, packing ring 5, output shaft flange plate 6, output shaft 7; torque is transmitted by input shaft flange plate, fluting bolt, output shaft flange plate; when torque surpasses setting value; the fluting bolt fracture; realize the power cut of input end and output terminal, prevent that overload from causing coupling and other relevant visual plant to damage.But when overload caused the fluting bolt fracture, input shaft flange plate disengagement out of control threw away, and the bolt member of fracture also may fly out, and brought great potential safety hazard for Field Force and equipment.
Summary of the invention
For overcoming the deficiencies in the prior art; goal of the invention of the present utility model is to provide a kind of coupling safety overload protection arrangement; by outside input shaft flange plate and output shaft flange plate, setting up protective equipment; set up limit structure between input shaft flange plate and the output shaft flange plate; prevent behind the bolt fracture that the two ends flange plate is thrown off and the bolt of fracture flies out, personnel and device security keep the scene intact.
For achieving the above object, the technical solution of the utility model is: input shaft, output shaft link together with input shaft flange plate, output shaft flange plate respectively, input shaft flange plate is connected by the fluting bolt with the output shaft flange plate, it is characterized in that: input shaft flange plate and output shaft flange plate are set up protective equipment outward respectively, in the hole of output shaft flange plate, between input shaft flange plate and the output shaft flange plate limit stoper is housed, on the fluting bolt lining is housed.
Described protective equipment is that input shaft flange plate and output shaft flange plate are equipped with gland outward.
Described limit stoper is that bearing is equipped with on bearing spacer both sides, and restraining position ring block groove on the bearing spacer is equipped with stop screw in the annular groove.
During overload, the fluting bolt fracture, input shaft flange plate loses diametrically with the output shaft flange plate and is connected, cut off transmission of power, the bolt of fracture falls in the gland, input shaft flange plate can be in the output shaft flange plate steadily idle running, thereby avoided overload to cause that coupling and other relevant visual plant damage, and input shaft flange plate and break bolt throw away and influence Field Force and device security.
The utility model compared with prior art has the following advantages:
When 1, transshipping, input shaft flange plate can steadily dally in the output shaft flange plate, can not throw off to throw away to injure peripheral personnel and equipment by a crashing object, break bolt falls in the gland, can not throw away, be convenient to cleaning, eliminated potential safety hazard to greatest extent along with the rotation of input shaft flange plate.
2, some can take out with lining because of bolt that breaking strain is stuck on the flange plate, make the replacing of fluting bolt more convenient, have shortened fault power time.
Description of drawings
Fig. 1 is a structural drawing of the present utility model;
Fig. 2 is prior art constructions figure.
Embodiment
As shown in Figure 1, input shaft 1 and input shaft flange plate 2 weld together, and some equally distributed bolts hole are arranged on the input shaft flange plate 2, and lining 5 is housed in the bolt hole, and gland 3 is installed in outside the input shaft flange plate 2 by screw 19 and packing ring 20; The bearing 10 on bearing spacer 11 both sides, bearing 12 are formed limit stoper, be installed in the hole of output shaft flange plate 15 by shaft retaining ring 13, between input shaft flange plate 2 and the output shaft flange plate 15, restraining position ring block groove on the bearing spacer 11 is equipped with stop screw 16 in the annular groove; Some equally distributed bolts hole are arranged on the output shaft flange plate 15, lining 6 is housed in the bolt hole, gland 7 is installed in outside the output shaft flange plate 15 by screw 17 and packing ring 18; Fluting bolt 4 is installed in 6 li of lining 5, linings, and nut 8, packing ring 9 are used for fastening fluting bolt 4, and output shaft 14 and output shaft flange plate 15 weld together.The utility model is realized transmission of power by input shaft flange plate 2, lining 5, fluting bolt 4, lining 6, output shaft flange plate 15.
During overload, the fracture of fluting bolt 4, input shaft flange plate 2 and output shaft flange plate 15 are connected radially losing, and transmission of power is interrupted, and bearing 10, bearing spacer 11, bearing 12 can steadily dally input shaft flange plate 2 in output terminal flange plate 15; Stop screw 16 is installed on the annular groove place of bearing spacer 11, and the moving axially of restriction bearing spacer 11 prevents that input shaft flange plate 2 and output shaft flange plate 15 from axially throwing off; Gland 3 and gland 7 can prevent to slot and throw away after bolt 4 ruptures, and lining 5, lining 6 make the fluting bolt 4 of fracture clear up more convenient and quicker.Shut down when repairing, unclamp stop screw 6 input shaft flange plate 2 and output shaft flange plate 15 are thrown off, unclamp screw 19 and can take off gland 3, unclamp screw 17 and can take off gland 7.The overload torque value can be regulated by the quantity of fluting bolt 4 and the size of fluting bolt 4 upper grooves, to adapt to the torque overload protection demand under the different operating modes.
