The agricultural main clutch device of voltage-controlled friction chip
Technical field
The workpiece power that the utility model structure belongs to a kind of large-scale self propelled harvester tool connects the improvement with separated safety apparatus structure, particularly a kind of for voltage-controlled friction chip main clutch.
Background technique
Current large-scale harvest machinery has become the market demand; but the critical piece as power source---main clutch; but become the bottleneck of development; traditional main clutch structure belongs to pull bar or guy structure; handle structure is complicated; can not meet the requirement of high-power machinery, lack overload protection, and cannot realize hommization and handle.
Summary of the invention
The purpose of this utility model is to provide a kind of voltage-controlled friction chip agricultural main clutch device, its compact structure, reasonable, performance safety is reliable, can effectively solve the clutch function of the power source of large-scale harvest machinery, can prevent that the damage parts phenomenon occurring because of overload from occurring, easy to operate.
The purpose of this utility model is achieved in that the agricultural main clutch device of a kind of voltage-controlled friction chip, be included on main clutch axle, by bearing, belt pulley be installed, on the spoke of belt pulley by bolt affixed ring gear, affixed the gear shaft with shelves dish on main clutch axle, rigidity friction plate and clutch top cover and gear shaft spline joint, bakelite friction plate and ring gear spline joint, it is characterized in that: on the sliding shaft sleeve of installing at main clutch axle, moving cooperation is installed with handgrip seat, the bearing support that bearing is housed is installed on handgrip seat, bearing support is connected with fixed plate, the articulated electric pushrod of ram seat is passed through in lower end at fixed plate, the gripper hinged in handgrip seat outer end matches with lock nut, electric pushrod draws and pushes away fixed plate and make gripper and lock nut act on respectively clutch top cover and gear shaft, to increase and to reduce the frictional force of rigidity friction plate and bakelite friction plate, reach the connection of belt pulley and main clutch axle with separated.
The utility model adopts a pair of tapered roller bearing to be connected with main clutch shaft by belt pulley, is having or not under load condition, and belt pulley and internal gear are all in idling conditions.When electric pushrod promotes electric pushrod seat, effect fixed plate, gripper bearing support, deep groove ball bearing and handgrip seat are slidably reciprocated on sliding shaft sleeve, interact power is passed to clutch top cover with gripper bearing support and three grippers, clutch top cover, bakelite friction plate, rigidity friction plate and gear shaft push generation frictional force mutually, internal gear is by strength transmission gear shaft, gear shaft is just connected with flat key with main clutch shaft, thereby reach automatically controlled power, connects and separated safety installations.
The utility model compact structure, reasonable, performance safety is reliable, has effectively solved the clutch function of the power source of large-scale harvest machinery, has prevented that the damage parts phenomenon occurring because of overload from occurring, easy to operate.

Embodiment
The agricultural main clutch device of a kind of voltage-controlled friction chip, as Fig. 1, Fig. 2, shown in Fig. 3, be included on main clutch axle 8, by bearing, belt pulley 4 be installed, on the spoke of belt pulley 4 by bolt affixed ring gear 5, affixed the gear shaft 12 with shelves dish on main clutch axle 8, rigidity friction plate 13 and clutch top cover 6 and gear shaft 12 spline joints, bakelite friction plate 14 and ring gear 5 spline joints, it is characterized in that: on the sliding shaft sleeve 9 of installing at main clutch axle 8, moving cooperation is installed with handgrip seat 10, the bearing support 11 that bearing is housed is installed on handgrip seat 10, bearing support 11 is connected with fixed plate 3, the articulated electric pushrod 1 of ram seat 2 is passed through in lower end at fixed plate 3, the gripper 7 hinged in handgrip Zuo10 outer end matches with lock nut 16, electric pushrod 1 draws and pushes away fixed plate 3 and make gripper 7 and lock nut 16 act on respectively clutch top cover 6 and gear shaft 12, to increase and to reduce the frictional force of rigidity friction plate 13 and bakelite friction plate 14, reach the connection of belt pulley 4 and main clutch axle 8 with separated.The quantity of bakelite friction plate 14 is 2, and rigidity friction plate 13 is 1.In the bearings mounted axis hole of belt pulley 4, on the axis hole wall between two dish bearings, jump-ring slot is being set, check ring 19 is installed in jump-ring slot.Belt pulley 4 is through hole, adds and does not need to change direction man-hour; Inner side machining clamp spring slot, increases notched check ring 19, thereby improves machining accuracy.The cage knob 18 that spring 17 controls are installed on the wheel hub of clutch top cover 6 matches with the opening lockhole of uniform setting on lock nut 16 outer peripheral surfaces.Loosening with clutch top cover 6 in order to prevent gear shaft 12, with spring 17, cage knob 18, lock nut 16 is blocked.Only press cage knob 18, could regulate lock nut 16.At the bearings mounted axis hole of belt pulley 4 two ends, rigid seal circle 15 is installed respectively.On the fitting surface of rigid seal circle 15 and main clutch axle 8,3 road oil grooves are being set.To prevent that dust from entering, extend the working life of bearing.
