Dentiform brake disk for air-jet loom
Technical field
The present invention relates to textile machine, specifically a kind of brake disc that is used on the air-jet loom.
Background technology
Air-jet loom is a kind of novel shuttleless loom, and her main feature is that rotating speed height, Homes Using TV height, automaticity height, varietal adaptation are strong.And, require more and more higher to the rotating speed of air-jet loom along with the aggravation of market competition.Existing air-jet loom as shown in Figure 1, manual gear 3 and brake disc 4 are connected on the main frame belt pulley 1 by hold-down screw 9.Therefore, brake disc and manual gear adhere to two parts mostly separately, and are installed on main frame belt pulley or other position respectively.This mounting means not only bulk is big, and complex structure is installed inconvenient; And reduced coupling stiffness between brake disc and the main frame belt pulley.
Summary of the invention
The objective of the invention is to design a kind of dentiform brake disk for air-jet loom,, make compact conformation, installation accuracy height, production efficiency height by the profile of tooth brake disc directly is installed on the main frame belt pulley.
According to design provided by the present invention, at an end of main frame belt pulley the profile of tooth brake disc is installed, in the outer rim of profile of tooth brake disc gear is arranged.
The main frame belt pulley is installed on the main shaft, and main shaft is installed on the frame, and bearing cap is arranged on frame, and dismountable hand wheel shaft is arranged on bearing cap, on hand wheel shaft, install handwheel and can with the gear of the gears engaged of profile of tooth brake disc outer rim.The restraining coil of profile of tooth brake disc is installed on frame.
Advantage of the present invention is: because manual gear and brake disc fuse, compare with the structure that brake disc adheres to two parts separately with original manual gear, the structure of this device is compact, and bulk is less; Secondly, this device has improved installation accuracy easily simultaneously in the installation location; The 3rd, improved the coupling stiffness between brake disc and main frame belt pulley; The 4th, reduced number of spare parts, improved production efficiency.

The specific embodiment
Shown in Fig. 2,3: main frame belt pulley 2 is installed on the main shaft, and main shaft is installed on the frame 8, and bearing cap 5 is arranged on frame 8, and dismountable hand wheel shaft 11 is arranged on bearing cap 5,
Handwheel 1 is installed on hand wheel shaft 11 And can with the gear of the gears engaged of profile of tooth brake disc 10 outer rimsAt an end of main frame belt pulley 2 profile of tooth brake disc 10 is installed, gear is arranged in the outer rim of profile of tooth brake disc 10.The restraining coil 6 of profile of tooth brake disc 10 is installed on frame 8.
Handwheel 1 utilizes its spindle nose kink in the hole of bearing cap 5, can arbitrarily take off, and main frame belt pulley 2 is fixed by bolts on the main shaft (not drawing among the figure), and wherein, profile of tooth brake disc 10 is fixed on the main frame belt pulley by screw.The restraining coil 6 of profile of tooth brake disc 10 is fixed on the frame 8 by set bolt 7.
When main frame ran well, handwheel 1 took off from bearing cap 5, and belt (not drawing among the figure) drives main frame belt pulley 2 and runs up, and loom main shaft and profile of tooth brake disc 10 be rotation together thereupon also.When loom control system sends stop sign, the motor outage, while restraining coil 6 gets electric at a certain special angle, produce braking moment, holds profile of tooth brake disc 10, thereby reaches the purpose of vehicle positioning stop.
When loom is in the debug phase, in the hole of bearing cap 5, at this moment the gears engaged of gear on the handwheel 1 and profile of tooth brake disc 10 outer rims is rotated handwheel 1, just can rotate loom handwheel 1 kink.
