Description
Technical field
A kind of pin tooth driving device, belongs to the mechanical transmission fields of the guide vane of vertical roll grinder powder selection device.
Background technology
Currently, the transmission device of the guide vane of vertical roll grinder powder selection device, there is two kinds of kinds of drive substantially：When
The shaft end of each widely used guide vane couples a stepper motor transmission device, this structure not only answer by transmission structures
It is miscellaneous, and electrical equipment control is more complicated；Second, using manually adjust, it is impossible to promptly and accurately according to the work feelings in vertical roll grinder
Condition, adjusts the water conservancy diversion angle of guide vane, and seriously affected powder selection device selects powder precision and grinding efficiency.
The content of the invention
The technical solution adopted by the present invention to solve the technical problems is：A kind of pin tooth driving device, including powder selection device
The clamping ring that sets of housing outer ring, horizontal pin braces bottom couples with sliding bearing B, and top couples with sliding bearing A, and covers
On the outside diameter of clamping ring, positioned by trim ring, it is characterised in that:Multiple pin tooth A are installed on horizontal pin braces, pin tooth A
Being engaged with the gear A of the output shaft end of the motor on electric machine support, multigroup pin tooth B is installed on vertical pin tooth frame, and
Engaged with the gear B installed in guide vane shaft end.
The multiple pin tooth A is that the maximum that the guide vane coupled according to gear B by guide vane axis need to rotate turns
Angle, and the hard-over that definite horizontal pin braces rotates, determine the number of teeth of pin tooth A.
Multigroup pin tooth B, is the group number that pin tooth B is determined according to the number of guide vane.
Compared with prior art, beneficial effect possessed by a kind of pin tooth driving device of the present invention is：
1st, this pin tooth driving device needs the stepper motor of a relatively high power, and water conservancy diversion can be driven by pin tooth driving device
Blade turns to suitable position, realizes that the finished particle of accurate control vertical roll grinder powder selection device selects powder precision and selects powder
Efficiency.
2nd, more set stepper motor transmission devices are saved, and electrical control system greatly simplifies.
3rd, complete machine structure is simple, and working service is convenient.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of pin tooth driving device of the present invention.
Wherein：1 clamping ring, 2 trim rings, 3 sliding bearing A, 4 horizontal pin braces, 5 motors, 6 electric machine supports, 7 gear As, 8 pins

Embodiment
Fig. 1 is a kind of most preferred embodiment of pin tooth driving device of the present invention, and 1 couple of present invention is done into one below in conjunction with the accompanying drawings
Walk explanation.
With reference to Fig. 1：A kind of pin tooth driving device, includes the clamping ring 1 of 14 outer ring of the housing setting of powder selection device, horizontal pin
4 bottom of braces couples with sliding bearing B13, and top couples with sliding bearing A3, and is sleeved on the outside diameter of clamping ring 1, passes through
Trim ring 2 positions, it is characterised in that:Multiple pin tooth A8 are installed on horizontal pin braces 4, and pin tooth A8 is with being installed on electric machine support 6
The gear A 7 of output shaft end of motor 5 engage, multigroup pin tooth B10 is installed on vertical pin tooth frame 9, and with installed in water conservancy diversion leaf
The gear B 11 at 12 end of bobbin engages.
The multiple pin tooth A8 is the maximum that need to be rotated by the guide vane that guide vane axis 12 couples according to gear B 11
Corner, and the hard-over that definite horizontal pin braces 4 rotates, determine the number of teeth of pin tooth A8.
Multigroup pin tooth B10, is the group number that pin tooth B10 is determined according to the number of guide vane.
Operation principle is as follows with the course of work：
Motor is rotated and engaged by gear A with pin tooth A, is driven horizontal pin braces to rotate, is arranged on horizontal pin braces bottom
Vertical pin tooth frame, by pin tooth B drive gear B rotate, gear B by guide vane axis drive guide vane turn over it is certain
Corner, controls the flow direction of the dust air-flow in powder selection device.
