Description
Technical field
The utility model relates to mining equiment field, particularly relates to the main shaft group on a kind of sand equipment processed.
Background technology
In mining equiment field, common be sand equipment processed is sand machine processed, has another name called vertical shaft impact crusher; Its operation principle material is divided into the material casting at middle part and the blanking of periphery, main shaft group rotor driven group high-speed rotation, and the material casting at middle part is dished out and collides with the blanking of periphery at a high speed by rotor set, by the broken building stones of the mode of " stone-crash-stone ".The main shaft group of existing sand machine processed, comprise main spindle box and main shaft, main shaft is positioned at main spindle box body inside by bearing; But existing main shaft group ubiquity the phenomenon of main shaft stability deficiency, bearing seal poor effect, thus equipment operation is caused to there is potential safety hazard.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide the main shaft group on a kind of sand equipment processed, and this main shaft group has main shaft good stability, the advantage that bearing seal effect is good.
In order to realize above-mentioned object, the utility model have employed following technical scheme:
Main shaft group on a kind of sand equipment processed, comprise main spindle box, and the main shaft in location and installation main spindle box, the inner top side of described main spindle box is provided with has upper roller bearing by top bearing cover location and installation, outer end and the main spindle box of top bearing cover closely cooperate, and are provided with seal disc between the inner of top bearing cover and main shaft; Be provided with O RunddichtringO between described upper seal disc and main shaft, between upper seal disc and top bearing cover, be provided with lip-type packing and Vd sealing ring; The inside lower end of described main spindle box has lower roller bearing and block bearing by lower bearing end cap location and installation, and lower roller bearing and block bearing set gradually from top to bottom, are also provided with cage ring between lower roller bearing and block bearing.
As preferably, described block bearing adopts deep groove ball bearing.
The utility model adopts technique scheme, main shaft group on this sand equipment processed comprises main spindle box and main shaft, main shaft is by upper roller bearing, lower roller bearing and block bearing location and installation in main spindle box, and block bearing, for increasing the holding capacity of main spindle box, ensures the stability of main shaft; And wherein, upper roller bearing is located by top bearing cover, be provided with lip-type packing and Vd sealing ring between top bearing cover and upper seal disc, between upper seal disc and main shaft, be provided with O RunddichtringO; The bearing seal effect of main shaft group is ensured by three kinds of sealing rings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
A main shaft group as shown in Figure 1 and Figure 2 on sand equipment processed, comprises main spindle box 51, and the main shaft 52 in location and installation main spindle box 51; The inner top side of described main spindle box 51 is provided with has upper roller bearing 53 by top bearing cover 54 location and installation, and outer end and the main spindle box 51 of top bearing cover 54 closely cooperate, and are provided with seal disc 55 between the inner of top bearing cover 54 and main shaft 52; Be provided with O RunddichtringO 551 between described upper seal disc 55 and main shaft 52, between upper seal disc 55 and top bearing cover 54, be provided with lip-type packing 552 and Vd sealing ring 553; The inside lower end of described main spindle box 51 has lower roller bearing 56 and block bearing 58 by lower bearing end cap 57 location and installation, and block bearing 58 preferentially adopts deep groove ball bearing; Lower roller bearing 56 and block bearing 58 set gradually from top to bottom, are also provided with cage ring between lower roller bearing 56 and block bearing 58.
The utility model adopts technique scheme, main shaft group on this sand equipment processed comprises main spindle box 51 and main shaft 52, main shaft 52 by upper roller bearing 53, lower roller bearing 56 and block bearing 58 location and installation in main spindle box 51, block bearing 58, for increasing the holding capacity of main spindle box 51, ensures the stability of main shaft 52; And wherein, upper roller bearing 53 is located by top bearing cover 54, between top bearing cover 54 and upper seal disc 55, be provided with lip-type packing 552 and Vd sealing ring 553, between upper seal disc 55 and main shaft 52, be provided with O RunddichtringO 551; The bearing seal effect of main shaft group is ensured by three kinds of sealing rings.
