Abstract
The invention relates to a novel friction clutch for a walking tractor, which is characterized in that the conical disc type friction clutch has a stationary fitted inclined surface; the stationary fitted inclined surface is installed on a transmission shaft on one side of a gear case; a rotatable fitted inclined surface and the stationary fitted inclined surface are oppositely installed on the transmission shaft; an operating lever is connected with the rotatable fitted inclined surface; a fly wheel is installed on the transmission shaft on the outer side of the rotatable fitted inclined surface through a bearing; a formed inner conical surface is formed on the outer side of the fly wheel; a drive disc is a conical body, the conical degree of the drive disc is the same as that of the inner conical surface at the inner side of the fly wheel, and the drive disc is installed on the transmission shaft on the outer side of the fly wheel through a spline; and a compression spring is installed on the transmission shaft on the outer side of the drive disc by a nut.
Description
Technical field:
The present invention relates to a kind of hand tractor friction clutch, particularly a kind of novel hand tractor friction clutch belongs to agricultural machinery technological field.
Background technique:
The structure of clutch is the important transmission part of hand tractor, at present, and in the structure of the clutch of hand tractor; The main friction clutch that adopts multi-disc type, though the clutch of this structure has compact structure, advantage that frictional force is bigger; Because structure aspects, also there is certain defective in this kind clutch, 1, Security is relatively poor; This kind clutch is because under separated state, its driven plate and driven shaft are in the state that rotates freely, and rotating plate is when high speed rotating; Dust and other foreign matter get between principal and subordinate's moving plate easily; Cause separating effect relatively poor or separate unclearly, not only damage easily relevant component, especially serious is to cause certain security incident; 2, this kind clutch is because complex structure also exists cost higher, and rate of fault is high, and the defective of installation and maintenance inconvenience.
Summary of the invention:
The objective of the invention is to: a kind of novel hand tractor friction clutch is provided, overcomes existing clutch owing to structure aspects, the Security that is caused is relatively poor, cost is higher, rate of fault is high and the defective of installation and maintenance inconvenience.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of novel hand tractor friction clutch, and it is by the cone disk type friction clutch the one fixed inclined-plane that agrees with to be arranged, fixed agreeing with on the transmission shaft that the inclined-plane is installed in gear-box one side; Agree with the inclined-plane turnably and the fixed inclined-plane that agrees with relatively is installed on the transmission shaft, operating handle with agree with the inclined-plane turnably and be connected; Flywheel is agreeing with on the transmission shaft in the inclined-plane outside through Bearing Installation turnably; There is the inner conical surface that produces in the outside of flywheel; Drive plate is a taper, and its tapering is identical with the inner conical surface of flywheel inboard, and drive plate is installed on the transmission shaft in the flywheel outside through spline; Pressure spring is installed on the transmission shaft in the drive plate outside, and nut is installed in pressure spring on the transmission shaft.
Beneficial effect: the present invention is owing to adopt the cone disk type friction clutch; The friction clutch that replaces existing square position formula; So, having overcome existing clutch owing to structure aspects, the Security that is caused is relatively poor, cost is high, rate of fault is higher and the defective of installation and maintenance inconvenience.
Description of drawings:
Fig. 1 is a structure principle chart of the present invention;
Shown in the figure: 1, gear-box; 2, the rotatable inclined-plane that agrees with; 3, operating handle; 4, transmission shaft; 5, bearing; 6, flywheel; 7, drive plate; 8, pressure spring; 9, nut; 10, the fixed inclined-plane that agrees with; 11, gear housing.
Embodiment:
The cone disk type friction clutch has a fixed inclined-plane 10 that agrees with, fixed agreeing with on the transmission shaft 4 that inclined-plane 10 is installed in gear-box 1 one sides; Agree with inclined-plane 2 turnably and relatively be installed on the transmission shaft 2 with the fixed inclined-plane 10 that agrees with, operating handle 3 with agree with inclined-plane 2 turnably and be connected; Flywheel 6 is installed on the transmission shaft 4 that agrees with 2 outsides, inclined-plane turnably through bearing 5; There is the inner conical surface that produces in the outside of flywheel 6; Drive plate 7 is tapers, and its tapering is identical with the inner conical surface of flywheel 6 inboards, and drive plate 7 is installed on the transmission shaft 4 in flywheel 6 outsides through spline; Pressure spring 8 is installed on the transmission shaft 4 in drive plate 7 outsides, and nut 9 is installed in pressure spring 8 on the transmission shaft 4.
