Description
Technical field
The invention belongs to mechanical manufacturing field, particularly relate to a kind of be applied to harvester, road roller, drilling equipment, etc. job that requires special skills wheel machine use driving speed reducer.
Background technology
Driving speed reducer is wheeled or the preferable driving means of the vehicle of caterpillar drive, its compact conformation, it is adapted for attachment in the equipment that space is less, owing to employing hardened gear and the ring gear of via nitride process, add the raising of production and assembly technique, driving speed reducer is made to have extraordinary bearing capacity, reliable and low noise, so, its range of application is the widest, the field that can use includes: excavator, airport wheel of vehicle drives, garbage truck vehicle wheel drives, the wheel of harvester drives, road roller hoofing part, drilling equipment.Driving speed reducer is the critical component guaranteeing its mobile security on wheeled formula vehicle, determines the quality of wheeled vehicle travelling performance to a great extent.At present, the A interface of traditional driving speed reducer and the fixing connection of support, power is delivered to high speed level sun gear from input interface spline housing connection sliding block, then transferring power to output interface B by Gear Planet Transmission drives walking mechanism to move, the defect of this device is: in the case of dynamic failure, brake (afunction voluntarily), engineering truck can not be dragged the most easily, make the movement of engineering truck be subject to certain restrictions.Therefore, in order to adapt to different working conditions, it is desirable to engineering truck, especially security performance is required that high engineering truck (afunction voluntarily) in the case of dynamic failure, brake can drag the most easily.For the defect overcoming traditional driving speed reducer to exist, tradition driving speed reducer is reformed by the present invention, innovation point is: as shown in Figure 1, Bolt dismantling on end cap is got off, anti-removable open loop, disengaging ring promotes ejector pin and slide block to move to left, slipper push compression spring, and spring is the tightest under the effect of limit shaft；Mutually disengaging between slide block and sun gear, when running out of steam, power intake is fixed, but output B (connecting with crawler belt or tire) is freely rotatable, it is achieved trailer function.Driving speed reducer after improving is used for engineering vehicle walking mechanism, in the case of dynamic failure, brake (afunction voluntarily), engineering truck can be dragged the most easily, have great practical value, and dependable performance, maintenance process is simple.
Summary of the invention
For the defect overcoming traditional driving speed reducer to exist, after traditional driving speed reducer is disengaged that ring is counter and fills by the present invention, when driving speed reducer runs out of steam, such as motor failure, system cut-off (brake cannot be opened), power intake is braked, but outfan B is freely rotatable, thus realize trailer function.
The present invention adopts the technical scheme that:
A kind of band machinery disengages the driving speed reducer of function, including: spline housing, limit shaft, slide block, spring, sun gear, ejector pin, end cap, bolt, disengagement ring；It is characterized in that: spline housing is fixing with limit shaft to be connected, spring housing is contained on limit shaft and loads among slide block, slide block left end loads spline housing and couples with spline housing internal spline, right-hand member loads sun gear and couples with sun gear internal spline, slide block can move along a straight line vertically, ejector pin is contained on end cap, disengages ring concave surface and is inwardly bolted on end cap.
The further technical scheme of the present invention is:
Coupled by spline between described slide block and spline housing, sun gear.
Described ejector pin uses as limit element.
The material of described sun gear is 20CrMnTi steel, heat treatment carburizing and quenching, and machining accuracy is GB/T10095-2008 precision 6 grades.
Described limit shaft, the raw material of ejector pin are 42CrMo steel, nitrogen treatment, and machining accuracy is GB/T10095-2008 precision 6 grades.
The invention has the beneficial effects as follows: provide a kind of band machinery and disengage the driving speed reducer of function, Bolt dismantling on end cap is got off by this driving speed reducer, anti-removable open loop, outfan can be made in the case of dynamic failure, brake to rotate freely, realize trailer function, engineering truck can be dragged the most easily, have great practical value, and dependable performance, maintenance process is simple.
Accompanying drawing illustrates:
If Fig. 1 is the sectional structure chart of the present invention.
Detailed description of the invention
Embodiment:
1, a kind of band machinery disengages the driving speed reducer of function, including: spline housing 1, limit shaft 2, slide block 3, spring 4, sun gear 5, ejector pin 6, end cap 7, bolt 8, disengagement ring 9；It is characterized in that: spline housing 1 is fixing with limit shaft 2 to be connected, spring housing 4 is contained on limit shaft 2 and loads among slide block 3, slide block 3 left end loads spline housing 1 and couples with spline housing 1 internal spline, right-hand member loads sun gear 5 and couples with sun gear 5 internal spline, slide block 3 can move along a straight line vertically, ejector pin 6 is contained on end cap 7, disengages ring 9 concave surface and is inwardly bolted on end cap 7.Coupled by spline between described slide block and spline housing, sun gear；Described ejector pin uses as limit element；The material of described sun gear is 20CrMnTi steel, heat treatment carburizing and quenching, and machining accuracy is GB/T10095-2008 precision 6 grades；Described limit shaft, the raw material of ejector pin are 42CrMo steel, nitrogen treatment, and machining accuracy is GB/T10095-2008 precision 6 grades.
2, band machinery is disengaged driving speed reducer interface A and the fixing connection of support of function, power is delivered to high speed level sun gear 5 from input interface spline housing 1 connection sliding block 3, then transfers power to output interface B by Gear Planet Transmission and makes engineering machinery move normally；In the case of dynamic failure, brake (afunction voluntarily), disengaging ring 9 and promote ejector pin 6 and slide block 3 to move to left, slide block 3 promotes compression spring 4, and spring 4 is the tightest under the effect of limit shaft 2；Mutually disengaging between slide block 3 and sun gear 5, power intake is braked, and makes output B be freely rotatable, it is achieved trailer function.
