Description
Technical field
The present invention relates to a kind of speed reducer, specifically a kind of concrete mixing and transporting car speed reducer, belongs to speed reducer technical field.
Background technique
Transit mixer in actual use, because of the impact of the various factors such as road conditions, operating mode, needs output flange can provide compared with wide-angle deflection.Existing transit mixer speed reducer, for realizing output flange angular deflection, generally adopts crowned teeth adpting flange 1-1 to add the structural type of non-standard self-aligning roller bearing 1-2, and is equipped with a bowl formula sealing 1-3 at output flange place, and its structural principle as shown in Figure 1.Described crowned teeth needs chain digital control gear hobbing machine or digital control gear shaper to process conventionally, and strong to device dependence, processing cost is higher; Described selfaligning roller bearing is for realizing compared with wide-angle deflection, adopt nonstandard design, inner ring is normal width, outer ring is specially widened, to guarantee that roller can not come off when compared with wide-angle deflection, and this kind of nonstandard bearing is mainly provided by FAG, and imported bearing cost is higher, has further improved the manufacture cost of speed reducer; The sealing of described bowl formula is ceaselessly pushed a certain side rubber lip limit because the frequent deflection of output flange causes, and has accelerated the aging of rubber, thereby has caused speed reducer leakage of oil.And maintain and replace is very inconvenient, conventionally also adopt import parts for ensuring the quality of products, cost is higher compared with conventional seals.
In sum, comparatively complexity of existing transit mixer speed reducer drive mechanism, and because adopting application specific architecture, non-standard, import parts to cause manufacture cost higher, inconvenient maintenance, is unfavorable for the raising of economic benefit.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of concrete mixing and transporting car speed reducer, is made up of standard piece, simple in structure, is convenient to maintenance, overcomes the dependence of existing transit mixer speed reducer to import parts, reduces manufacture cost.
For solving the problems of the technologies described above, the present invention includes planet carrier, also comprise the double-row conical bearing of spherical hinge connection mechanism, back-to-back configuration, radially reinforced seal and output flange;
Described spherical hinge connection mechanism is made up of the outer bulb on interior ball-and-socket and base plate on housing;
Described planet carrier is connected with output flange by interior external splines;
The double-row conical bearing of described back-to-back configuration is fastened on output flange running shaft by interference fit; The double-row conical bearing of described back-to-back configuration, between two outer rings of two tapered roller bearings and two inner rings, respectively there is a spacer ring, the load line of two bearings separates towards bearing axis, is the bearing configuration that rigidity is relatively high, and can bears tilting moment.
Described radially reinforced seal is set in output flange running shaft outside, prevents that with this speed reducer inner chamber gear oil from leaking; Described radially reinforced seal is for having deformable cross section, and inside has metal frame to support, and the radial force applying by sealing cutting edge prevents the seal ring of fluid leakage.
Further, around spherical hinge connection mechanism, be arranged with two or more than two for clamping the damping rubber block of spherical hinge connection mechanism, reduce the mixing drum impact force of bringing that deflects, the rubber-metal piece that provides buffering to support for speed reducer beat.
Further, the double-row conical bearing of back-to-back configuration is connected with output flange by locking nut, thereby regulates bearing clearance between the two by locking nut, to guarantee that two bearings effectively work.
Compared with prior art, the present invention has the following advantages:
1), adopt spherical hinge connection mechanism to realize output flange deflection, cancel crowned teeth connecting flange structure, make output flange and planet carrier by spline joint, can significantly reduce planet carrier outside dimension and height, the forging cost of demoting;
2), use double-row conical bearing to replace nonstandard selfaligning roller bearing, the double-row conical bearing of back-to-back configuration can bear tilting moment, guarantees the rigidity of whole system with this.Replace nonstandard bearing with standard rolling bearing, also can reduce purchase cost and guarantee the supply of material in time.Wherein, the double-row conical bearing of back-to-back configuration can adopt the bearing of two same model, also can adopt different tapered roller bearings according to force analysis, can reduce costs simultaneously;
3), use common radially reinforced seal to replace the sealing of bowl formula, because output flange is with respect to the bearing hole of base housing, just do the pure rotation around its axis, no longer include deflection, and be atmospheric pressure sealed, use common radially reinforced seal can meet the seal request of speed reducer;
4), between base plate and reducer shell, increase damping rubber block, slow down the mixing drum impact force of bringing that deflects, extended the working life of equipment;
5), the present invention is simple in structure, not easy to wear, be easy to manufacture, and do not rely on import parts, low cost of manufacture, and the economic benefit that is conducive to improve enterprise easy to maintenance.
