Abstract
The utility model relates to an anti-counter-rotation device for a motor tractor, which comprises a motor rotor, an anti-counter-rotation ratchet, an anti-counter-rotation member and a combined gear. The device is characterized in that one end surface of the combined gear is provided with an inner concave part and the end surface is positioned right facing the anti-counter-rotation member. The inner concave part and the revolution center of the combined gear are coaxially disposed. One part of the anti-counter-rotation member downwardly extends into the inner concave part to form an engagement part with the combined gear. The viscous lubricating grease is smeared in the inner concave part. Since the viscous lubricating grease is smeared in the inner concave part of the combined gear, the viscous lubricating grease in the combined gear is prevented from overflowing during rotation. Therefore, the loss of the viscous lubricating grease during long-time usage can be effectively prevented, and the lubrication and friction service life of the viscous lubricating grease is prolonged. The anti-counter-rotation member is embedded in the inner concave part. In this way, the utilization space along the axial direction is effectively utilized due to the embedded arrangement of the anti-counter-rotation member.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of anti-reverse device of using of motor tractor, comprise rotor, anti-reverse with ratchet, anti-reverse with member and combination gear, described combination gear engages with the structure gear drive on rotor, described be anti-reversely fixedly installed with ratchet and rotor, described combination gear and be anti-reversely arranged on gyroaxis with component coaxial, and at the anti-reverse viscosity lubricating grease of smearing with the junction surface place of member and combination gear, described anti-reverse with having on member in order to described anti-reverse by ratchet competing braking parts, this braking parts is stretched out outside combination gear, it is characterized in that: described combination gear with anti-reverse with being provided with inner fovea part on the just right end face of member, the centre of gyration of inner fovea part and combination gear coaxially arranges, the described anti-reverse part with member stretches into the junction surface of inner fovea part formation and combination gear downwards, and described viscosity lubricating grease is applied in described inner fovea part.
Improve further, the bottom surface of above-mentioned inner fovea part is provided with evagination and the annular wall with the coaxial setting of the centre of gyration of combination gear, it is inside and outside two parts by female parts that this annular wall is positioned at inner fovea part, the described anti-reverse cannelure embedding for annular wall that is provided with member corresponding end-faces, the anti-reverse sidewall with member has curved elasticity support arm, and the outer end of elasticity support arm has the friction part inconsistent with described annular wall outer peripheral face.Anti-reverse have the friction part inconsistent with annular wall outer peripheral face with member, friction part draws to ensure between friction part and annular wall, to have balanced soft contact force life-saving by flexible leg, this soft contact force plays the effect of auxiliary contact combination gear, even have under certain miss status at viscosity lubricating grease, the direction rotation of combination gear also can drive anti-reverse with member, guarantee anti-reversely can be under inverted status mutually conflict with ratchet with anti-reverse by the braking parts on member, realize the braking to rotor.
Improve further, above-mentioned elasticity support arm has and be arranged in parallel with the centre of gyration of combination gear and to downward-extension limited post.After assembling, limited post can be conflicted with the stationary plane of motor tractor inside, prevents that the friction part on elasticity support arm from popping up and separating with annular wall, also just guarantees the stability that the friction part on elasticity support arm contacts with annular wall.
Above-mentionedly anti-reversely be provided with perforation with member.Anti-reverse with member its weight must be lighter and handier, perforation is set can effectively reduces the weight of anti-reverse member so that the reverse rotation of combination gear can more easily drive and anti-reversely reverse with member thereupon, reduce the energy loss of motor tractor.
Above-mentionedly anti-reversely be provided with limited location fork with contiguous braking parts position on member.Limited location fork can be conflicted and coordinate with the gear post in motor tractor, make in motor forward process, the anti-reverse member of using is with combination gear forward, after limited location fork contacts with gear post, anti-reversely skid with member is relative with combination gear, ensure the anti-reverse braking parts with member away from anti-reverse with in ratchet, prevent from again anti-reversely continuing to interfere with combination gear rotation and other parts in motor tractor with member.
Above-mentionedly anti-reversely expose combination gear outside by braking parts side on member.Facilitate like this stop part to coordinate with ratchet with anti-reverse.
Compared with prior art, the utility model has the advantage of: viscosity lubricating grease is applied in and in the inner fovea part of combination gear, can prevents that combination gear viscosity lubricating grease in it in rotary course from overflowing, effectively prevent that the loss that viscosity is lubricated after long-time use from extending the lubricated and friction life-span, anti-reversely be embedded in inner fovea part by member part, the set-up mode of embedded shape can also effectively utilize the space that utilizes on axial direction.
