The utility model discloses a coal pulverizer selection powder machine transmission is equipped with the recess on the transmission belt dish, be equipped with on the flange with recess assorted boss, on original bolted connection's basis, increased the recess and be connected with the boss for joint strength between flange and the transmission belt dish obviously increases, and the bolt is difficult to the fracture, reduces the trouble incidence.
Description
Technical Field
The utility model relates to a selection powder machine technical field, concretely relates to coal pulverizer selection powder machine transmission.
Background
The powder separation principle of the coal mill powder separator is that materials fall onto a vertical mill millstone through a discharging chute arranged on the powder separator, particles with different grade diameters are formed through grinding and pressing of the mill rolls, the particles with the diameters meeting requirements are rotated through different rotating speeds of a rotor of the powder separator, and the particles are taken away through an air conveying system. The rotor operation of the coal mill separator is influenced by various factors such as feeding amount, coal humidity and the like, the working load is unstable and small in time, the rotating speed of the separator rotor is regulated through a variable-frequency speed regulator, the operating speed is different, the separator rotor is fixed with a transmission belt disc through a flange on a bearing seat, when the load is uneven, the bolt is easy to shear and break, the breakage of individual bolt is discovered in time, other bolt breakage can be caused, the contact surface of the flange and the transmission belt disc can generate friction, dry friction is caused, and the transmission belt disc and the flange are damaged. The transmission belt pulley is a casting, and the manufacturing period is long. The assembly period of the flange and the bearing seat is long, if spare parts are manufactured, the value is high, once the spare parts break down, the operation rate of equipment is seriously influenced, and the maintenance cost is increased.
Disclosure of Invention
The utility model aims to solve the technical problem that not enough the providing a coal mill selection powder machine transmission to above-mentioned prior art, this coal mill selection powder machine transmission is equipped with the recess on the transmission belt dish, be equipped with on the flange with recess assorted boss, on original bolted connection's basis, increased the recess and be connected with the boss for joint strength between flange and the transmission belt dish obviously increases, and the bolt is difficult to the fracture, reduces the fault incidence.
In order to realize the technical purpose, the utility model discloses the technical scheme who takes does:
a transmission device of a coal mill powder concentrator comprises a bearing seat, a transmission belt disc and a flange, wherein a bearing is installed in the bearing seat, the inner ring of the bearing is connected with the flange, and the top of the flange is connected with the bottom of the transmission belt disc; the flange is characterized in that a plurality of grooves are formed in the contact surface of the transmission belt disc and the flange, a plurality of bosses matched with the grooves are arranged on the contact surface of the flange and the transmission belt disc, the bosses on the flange are inserted into the grooves in the transmission belt disc, and the flange is fixedly connected with the transmission belt disc through bolts.
As the utility model discloses further modified technical scheme still includes transmission system, transmission system passes through the belt and is connected with the transmission belt dish, transmission system is used for driving the transmission belt dish rotatory.
As a further improved technical scheme of the utility model, the bottom of flange is passed through the bolt and is connected with the selection powder machine rotor.
The utility model has the advantages that:
the utility model discloses flange joint plane on the bearing frame increases the boss except original connecting thread, and the number is decided according to the size of coal pulverizer specification, and the number specification of boss cooperatees on the and the flange except former jogged joint department in transmission belt dish below and flange contact surface department increases the recess. Originally only have bolted connection, increase recess, boss connection again now, joint strength obviously increases, and the bolt is difficult to the fracture, reduces the trouble incidence.

Fig. 2 is a schematic view of the connection structure between the transmission system and the transmission belt pulley of the present invention.
Detailed Description
The following further description of embodiments of the invention is made with reference to the accompanying drawings:
as shown in fig. 1 and 2, the transmission device of the coal mill powder concentrator comprises a bearing seat 1, a transmission belt disc 2 and a flange 3, wherein a bearing is installed in the bearing seat 1, the inner ring of the bearing is connected with the flange 3, and the top of the flange 3 is connected with the bottom of the transmission belt disc 2. Be equipped with a plurality of recesses 4 on the contact surface of transmission belt dish 2 and flange 3, be equipped with a plurality of bosses 5 that are used for with recess 4 assorted on the contact surface of flange 3 and transmission belt dish 2, boss 5 on the flange 3 inserts in the recess 4 on the transmission belt dish 2, and flange 3 and transmission belt dish 2 are through 6 fixed connection of a plurality of bolts. Fig. 1 shows 8 the mounting position of the bolt 6.
In this embodiment, as shown in fig. 2, the powder concentrator further includes a transmission system 7, the transmission system 7 is connected to the transmission belt disc 2 through a belt, and the transmission system 7 is configured to drive the transmission belt disc 2 to rotate, so as to drive the rotor of the powder concentrator to rotate through the flange 3. The structure of the transmission system 7 adopts the structure commonly used in the prior art.
In this embodiment, the bottom of the flange 3 is connected with the top of the hollow shaft through a plurality of bolts 6, and the bottom of the hollow shaft is connected with the powder concentrator rotor through the bolts 6.
The transmission system 7 of the embodiment drives the rotor of the powder concentrator to rotate through the groove 4 of the transmission belt pulley 2 and the boss 5 (also connected by the bolt 6) on the flange 3.
