Background technique
Railway switch is positioned at outdoor, environment is abominable, its conversion resistance force changes greatly, may press from both sides foreign matter between its tongue and the stock rail simultaneously, if switch machine conversion power is excessive, may be under the not closely connected situation of tongue and stock rail locking and provide expression, can threaten traffic safety like this, therefore changing the switch machine that track switch uses all has the device that limits maximum conversion power.Electric point machine is friction axis coupling normally, realizes by setting a suitable frictional force.Therefore concerning electric point machine, whether friction axis coupling stable, reliably determining the success or failure of switch machine, if friction axis coupling ouput force instability, then switch machine is with regard to cisco unity malfunction, even may produce serious accident.If the friction axis coupling ouput force in use diminishes, then may make track switch can not finish conversion, thereby have influence on conveying efficiency; If the friction axis coupling ouput force in use becomes greatly, then may be under switch machine should not the situation of locking locking, train by the time may have an accident.As seen stable, the reliably working of friction axis coupling directly influences efficiency of operation and traffic safety in the switch machine.
The setting of friction axis coupling ouput force is to realize that by the spring pressure of adjusting the pressing friction sheet its adjustment is two-way.In the structure of friction axis coupling, frictional force can drive spring when adjusting spring pressure at present, because the state of spring is undesired, the friction axis coupling ouput force can change a lot.
The model utility content
The purpose of this utility model provides a kind of simple in structure, and is reliable, uses easily and prevents the structure that pressure spring tilts in the switch machine friction axis coupling.
The technical solution of the utility model is, prevent the structure that pressure spring tilts in the switch machine friction axis coupling, comprise and adjust nut 1, thrust mechanism 2, pressing plate 3, spring 4, housing 5, adjust nut 1 and housing 5 by being threaded, it is characterized in that: between spring 4 in housing 5 and the adjustment nut 1 thrust mechanism 2 is arranged, thrust mechanism 2 places between the adjustment nut 1 of housing 5 inner chambers and band boss.
Described thrust mechanism 2 is thrust-bearings, thrust-bearing is made of blowout patche 6, rolling element 7 and spring-leaf retainer 8, rolling element 7 in the right clamping of blowout patche 6 and spring-leaf retainer 8 one the first from left, blowout patche 6 is connected in the draw-in groove 11 of adjusting nut 1, spring-leaf retainer 8 is outside the boss of adjusting nut 1, and spring-leaf retainer 8 in spring 4 crimping.
Described thrust mechanism 2 is made of thrust cages for needle assembly 9 and thrust washer 10, at spring 4 with adjust between the nut 1 fixedly thrust cages for needle assembly 9 and thrust washer 10, thrust washer 10 has two, thrust cages for needle assembly 9 in two right clampings of thrust washer 10 1 the first from left, the thrust washer of right-hand member is connected in the draw-in groove 11 of adjusting nut 1, the thrust washer 10 of left end is outside the boss of adjusting nut 1, and the thrust washer 10 of left end in spring 4 crimping.
Between thrust mechanism 2 and spring 4, pressing plate 3 is arranged.
Characteristics of the present utility model are: owing between spring 4 and adjustment nut 1 thrust mechanism 2 is installed, thrust mechanism 2 is thrust-bearing or thrust cages for needle assembly 9 and thrust washer 10, when nut 1 is adjusted in turn, retainer assembly in thrust-bearing or thrust cages for needle assembly 9 and the thrust washer 10 is rotation and then, but being close to the pressing plate 3 of spring 4 or thrust washer 10 and spring 4 can turn, when adjusting the decrement of spring 4, spring 4 just can not have a down dip in the effect of frictional force like this.
The utility model is described in further detail below in conjunction with embodiment's accompanying drawing:
