Together, it is coaxially fixedly mounted with a chassis in the top surface of worm gear, is coaxially fixedly mounted with a limit sleeve in chassis face, signal is inserted in limit sleeve and is referred to
Show that the cam support axis of device, the signal indicator include two cams, cam support axis, two contact-making switches, terminals
Son, instruction disk, instruction disk housing, circular support lid, the circular support lid inserting are fixed on two circles that cap top surface is formed with
Between protrusion, the lower part of cam support axis is pierced by insertion limit sleeve from circular support lid, and is clamped and fixed with limit sleeve, convex
The top suit of wheel support shaft fixes two cams, is coaxially fixedly mounted with an instruction disk on the top of cam support axis, the one of instruction disk
Pointer is installed in side, and pointer lower part is fixedly mounted with circular support hd top face, an instruction disk housing is fixedly mounted with above circular support lid, is referred to
Showing and is formed with side outlet hole below disk housing, two cams are alternatively arranged up and down, two cams, one contact-making switch of each correspondence,
Two contact-making switches are mounted on circular support hd top face, contact-making switch and the terminals for being packed in circular support hd top face by bracket
Son is connected by conducting wire, and the outlet of connecting terminal is drawn from the side outlet hole of instruction disk housing sidewall, is connect with Central Control Room.
Moreover, by buckle or being bolted in limit sleeve and cam support axis.
Moreover, circular support lid projects through bolt with outer ring or snaps connection.The advantages of the utility model and actively effect
Fruit is:
1, this worm wheel head can be produced in batches with modular form, reduce manufacturing cost and mounting cost.
2, this worm wheel head need to only fix several bolts or buckle at housing, remaining is inserting, easy to operate, time saving province
Power.
Detailed description of the invention
