Description
Technical field
The utility model is specifically related to a kind of integral type differential mechainsm for miniature tiller.
Background technique
Because current agricultural microtilling machine build is less, so inner space is limited, what mainly adopt when designing is indifferential mode, and walking gear directly drives two cutters, synchronously moves in the same way during work, and turning to during use painstakingly again can not flexible operating.Power transmission is switched according to clutch, not only complicated operation, small product size is comparatively large and weigh, part is again had to use the outer plug-in type design of general output shaft, product mix position is more, use middle because of needs transmit larger torsion, Product Assembly gap will directly affect transmission of power and working life.
Next adopts clutch to switch power transmission, complicated operation, small product size is comparatively large and weigh, part is again had to use the outer plug-in type design of general output shaft, product mix position is more, use middle because of the larger torsion of needs transmission, the assurance in Product Assembly gap will directly affect transmission of power and working life.
Model utility content
It is little that the utility model is intended to provide one to take up room, stressed large integral type differential mechainsm for miniature tiller.
Integral type differential mechainsm for miniature tiller in this programme, comprise the semiaxis and differential gear that are wholely set, planetary pinion is meshed with differential gear, and also comprise differential gear and two limit lids, described limit is covered and is set in respectively on two semiaxis and offsets respectively with differential gear two end faces; Described differential gear comprises the differential body limit be set in respectively on two semiaxis and covers and walking gear, and described walking gear comprises umbrella gear and is arranged on the planetary pinion groove of umbrella gear one end face; The madial wall of described planetary pinion groove is circular arc, and described planetary pinion symmetry is located on the sidewall of planetary pinion groove, the axes normal of described planetary axis and umbrella gear.
The utility model has the advantages that: (1) is covered due to limit and offseted with differential gear two end faces respectively, and when differential gear transmission is stressed, differential gear rotatingshaft not easily tilts, and greatly reduces wearing and tearing, improves working life; (2) because differential body limit lid is fixedly connected with walking gear, when umbrella gear engagement driving, stressed the while of differential body limit lid and walking gear, what improve walking gear is subject to force intensity; (3) because umbrella gear one end face is provided with planetary pinion groove, the madial wall of planetary pinion groove is circular arc, and the planetary large end of bevel gear structure is the cambered surface of evagination, adapts, make full use of space with the madial wall of planetary pinion groove.
Further, be provided with bearing and oil sealing between described limit lid and semiaxis, described bearing is between oil sealing and differential gear.Such oil sealing the minimizing of maximum flow can enter bearing and planetary dust, reduces gear wear.
Further, all sides of described differential body limit lid are provided with connection boss, described connection boss are also evenly equipped with several fastening screw trip bolts be fixedly connected with planetary pinion groove, are convenient to differential body limit lid and install with walking gear and dismantle.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model integral type differential mechainsm for miniature tiller embodiment;
Fig. 2 is the structural representation of the utility model integral type differential mechainsm for miniature tiller embodiment differential gear.
In figure, 1 is umbrella gear, and 2 is differential body limit lid, and 3 is fastening screw trip bolt, and 4 is planetary pinion groove, and 5 is axis hole, and 6 is bearing, and 7 is oil sealing, and 8 is limit lid, and 9 is differential gear, and 10 is planetary pinion.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
According to Fig. 1, integral type differential mechainsm for miniature tiller, comprises two semiaxis be wholely set and differential gear 9, and this differential gear 9 is oppositely arranged, and two planetary pinions 10 are all meshed with differential gear 9.Differential gear comprises differential body limit lid 2 and walking gear, and walking gear is made up of umbrella gear 1 and the planetary pinion groove 4 that is arranged on umbrella gear 1 one end face.In order to better utilize space, the inwall of planetary pinion groove 4 is the circular arc adapted with planetary pinion 10.Planetary pinion 10 is positioned at the space that differential body limit lid 2 is formed with planetary pinion groove 4, and planetary pinion 10 is rotationally connected and is symmetrical arranged with the sidewall of planetary pinion groove 4, the axis of planetary pinion 10 and the axes normal of umbrella gear 1.Install for the ease of differential body limit lid 2 with walking gear and dismantle, all sides of differential body limit lid 2 are provided with connection boss, and differential body limit lid 2 is fixedly connected with walking gear by this connection boss by two fastening screw trip bolts 3.Two limits lid 8 be positioned at differential gear both sides and cover 2 respectively with differential body limit, umbrella gear 1 offsets.In order to reduce the dust entering bearing 6 and planetary pinion 10, reduce gear wear, be provided with coaxial oil sealing 7 and two bearings 6 between limit lid 8 and semiaxis, this bearing 6 is between oil sealing 7 and differential gear.
During use, planetary pinion 10 is arranged on the stationary axle in planetary pinion groove 4, and differential gear 9 is positioned at planetary pinion groove 4 and engages with planetary pinion groove 4, and the semiaxis of differential gear 9 is through axis hole 5.When umbrella gear 1 engagement driving, stressed the while of differential body limit lid 2 and walking gear, what improve walking gear is subject to force intensity.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
