Abstract
The utility model discloses a kind of modified model roller mill speed reducer, angular wheel shaft (1) is fixed on bearing housing (2) by tapered roller bearing (3) and selfaligning roller bearing (4), crowned teeth axle (20) is arranged on upper box (5) by roller bearing (15) and tapered roller bearing (19) and lower box (18) is gone up and connected with sun gear (11) by attachment tooth cover (12), umbrella gear (16) is fixed on crowned teeth axle (20) by key, output flange (7), planet carrier (10) and planet wheel (8) are fixed together by planet wheel shaft (9) and are supported by thrust-bearing (6), overall formation Novel vertical mill speed reducer.The utility model adopts the casing of two-piece unit, easily manufactured, and technique is simple, installs and uses easy to maintenance, and planet wheel shaft had not only been used for fixing planet wheel simultaneously but also the output torque of planet carrier is passed to output flange, and compact structure is reliable.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of modified model roller mill speed reducer.
Background technique
Domestic existing roller mill speed reducer body mainly contains two kinds of structural types, one is integrated type, another kind is the structural type that upper box adds ring gear and adds lower box again, along with expanding economy and technological progress, the use of the type speed reducer is more and more extensive, the problems such as use specification is increasing, and its machining cylinder block, final assembly and maintenance are inconvenient are outstanding all the more.
Summary of the invention
The purpose of this utility model is: design a kind of modified model roller mill speed reducer, has both ensured that manufacture cost was relatively low, and technique is simple, ensures again to install and use reliably, easy to maintenance.
Technical solution of the present utility model is: this speed reducer comprises angular wheel shaft, umbrella gear, crowned teeth axle, sun gear, planet wheel, ring gear, upper box, lower box and output flange, upper box and lower box bolt group are fixed, in upper box, ring gear is installed, upper box installs output flange, the two ends of angular wheel shaft are arranged in bearing housing through tapered roller bearing and selfaligning roller bearing respectively, crowned teeth axle to be arranged on upper box and lower box by roller bearing and tapered roller bearing and to be connected with sun gear by attachment tooth cover, umbrella gear is fixed on crowned teeth axle by key, output flange, planet carrier and planet wheel are fixed together by planet wheel shaft and are supported by thrust-bearing, planet wheel shaft not only fixes planet wheel but also the output torque of planet carrier is passed to output flange, one end of planet carrier is fixed on upper box by inner ring without the roller bearing of rib, overall formation roller mill speed reducer.
The utility model has the following advantages:
1, adopt the casing of two-piece unit, easily manufactured, technique is simple.
2, one end of planet carrier and one end of crowned teeth axle are fixed without the roller bearing of rib and upper box by inner ring, make planet carrier and upper box easily install and take out, easy to maintenance.
3, planet wheel shaft was both used for fixing planet wheel, and again the output torque of planet carrier is passed to output flange, compact structure is reliable simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1 angular wheel shaft, 2 bearing housings, 3 tapered roller bearings, 4 selfaligning roller bearings, 5 upper boxes, 6 thrust-bearings, 7 output flanges, 8 planet wheels, 9 planet wheel shafts, 10 planet carriers, 11 sun gears, 12 attachment tooth covers, 13 ring gears, 14 roller bearings, 15 roller bearings, 16 umbrella gear, 17 bolt groups, 18 lower boxes, 19 tapered roller bearings, 20 crowned teeth axles.
Embodiment
Accompanying drawing discloses concrete structure of the present utility model without limitation, and below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, this speed reducer comprises angular wheel shaft 1, umbrella gear 16, crowned teeth axle 20, sun gear 11, planet wheel 8, ring gear 13, upper box 5, lower box 18 and output flange 7, upper box 5 and lower box 18 bolt group 17 are fixed, in upper box 5, ring gear 13 is installed, upper box 5 is installed output flange 7, the two ends of angular wheel shaft 1 are arranged in bearing housing 2 through tapered roller bearing 3 and selfaligning roller bearing 4 respectively, crowned teeth axle 20 to be arranged on upper box 5 and lower box 18 by roller bearing 15 and tapered roller bearing 19 and to be connected with sun gear 11 by attachment tooth cover 12, umbrella gear 16 is fixed on crowned teeth axle 20 by key, output flange 7, planet carrier 10 and planet wheel 8 are fixed together by planet wheel shaft 9 and are supported by thrust-bearing 6, planet wheel shaft 9 not only fixes planet wheel 8 but also the output torque of planet carrier 10 is passed to output flange 7, one end of planet carrier 10 is fixed on upper box 5 by inner ring without the roller bearing 14 of rib, overall formation roller mill speed reducer.
