Abstract
The utility model relates to the field of mechanical manufacturing, and in particular relates to a ratchet wheel mechanism of a mesh-belt quenching furnace. The ratchet wheel mechanism of the mesh-belt quenching furnace comprises a round ratchet wheel, pawls and an oscillating bar; the pawls are regularly arranged around the side edge of the ratchet wheel; a through hole formed in the ratchet wheel is arranged at an axis of the ratchet wheel and passes through the ratchet wheel; the ratchet wheel is connected with one end of the oscillating rod through a shaft; holes are formed in the other end of the oscillating rod; the pawls are hinged to the oscillating rod through the holes; the pawls of the ratchet wheel are asymmetrically trapezoidal; the pawls are four-teeth pawls engaged with the ratchet wheels by teeth shape; the ratchet wheel is 8mm in thickness, and the pawls are 7mm in thickness. According to the technical scheme, the ratchet wheel mechanism of the mesh-belt quenching furnace has the advantages that the stressing capacity is high, and the service life is long.
Description
Technical field
The utility model relates to mechanical manufacturing field, is specifically related to a kind of ratchet mechanism of mesh-belt quenching furnace.
Background technique
Ratchet mechanism, a kind of one-way intermittent motion mechanism being formed by ratchet and pawl.The advantages such as ratchet mechanism is simple in structure with it, easy processing, extensive use in all kinds of machinery, is used for feeding, transposition or calibration, brakes, surmounts, the occasion such as counting.The ratchet mechanism of prior art, adopt a tooth papillae pawl, the ratchet number of teeth is generally 80, and the ratchet thickness of prior art is 3mm, ratchet thickness is 2mm, and ratchet and pawl is in the process of braking, ratchet and pawl easily produces fatigue damage, cause click to damage, blowing out is changed frequent, to production, brings many troubles.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide that a kind of stress-bearing capability is strong, the ratchet mechanism of the mesh-belt quenching furnace of long service life.
In order to solve the problems of the technologies described above, the utility model provides a kind of ratchet mechanism of mesh-belt quenching furnace, comprise ratchet, ratchet and fork, described ratchet is circular, be periphery and be placed with ratchet in edge the rule of described ratchet, inside at described ratchet arranges through hole, described through hole is arranged at the axle center of described ratchet and connects described ratchet, ratchet is connected with fork one end by axle, the other one end of described fork arranges porose, ratchet is articulated with on fork by hole, and the ratchet shape of described ratchet is set as asymmetric trapezoidal; Ratchet is and four tooth papillae pawls of the profile of tooth engagement of described ratchet, and the thickness of ratchet is set to 8mm, and the thickness of ratchet is set to 7mm.
Adopt the tool of technique scheme to have the following advantages: described ratchet is made as four tooth papillae pawls, ratchet and ratchet are in the process of braking, stressed relatively stable, reduced the fatigue damage between ratchet and ratchet, the thickness of ratchet and pawl is increased respectively to 5mm, increase to a certain extent the stress-bearing capability of click, reduced the damage of click; The profile of tooth of while ratchet is set as asymmetric trapezoidal, makes ratchet mechanism can bear larger load, not fragile.
As preferred version, in order further to increase the intensity of ratchet, the number of teeth of described ratchet is made as 72.
As preferred version, in driving ratchet rotation process, ratchet and pawl is not fragile, and described ratchet is elastic pawl.
Accompanying drawing explanation
Fig. 1 is to be structural representation of the present utility model;
In figure: 1-fork, 2-ratchet, 3-ratchet, 4-axle.
embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
As shown in Figure 1: the utility model provides a kind of ratchet mechanism of mesh-belt quenching furnace, comprise ratchet 3, ratchet 2 and fork 1, ratchet 3 is circular, be periphery and be placed with ratchet in edge the rule of ratchet 3, in the inside of ratchet 3, through hole is set, through hole is arranged at the axle center of ratchet 3 and connects ratchet 3, ratchet 3 is connected with fork 1 one end by axle 4, the other one end of fork 1 arranges porose, and ratchet 2 is articulated with on fork 1 by hole, and the ratchet shape of ratchet 3 is set as asymmetric trapezoidal; Ratchet 2 is the four tooth papillae pawls with the profile of tooth engagement of ratchet 3, the thickness of ratchet 3 is set to 8mm, the thickness of ratchet 2 is set to 7mm, the number of teeth of ratchet 3 is made as 72, increase the intensity of ratchet 3, ratchet 2 is elastic pawl, and when fork 1 counterclockwise swings, ratchet 2 just inserts hook tooth to promote ratchet 3 rotating in same directions; When fork 1 clockwise direction swings, ratchet 2 slips on ratchet 3, and ratchet 3 stops operating.Fork 1 reciprocally swinging, ratchet 2 promotes ratchet 3 intermittent rotaries.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (3)
1. the ratchet mechanism of a mesh-belt quenching furnace, comprise ratchet, ratchet and fork, described ratchet is circular, be periphery and be placed with ratchet in edge the rule of described ratchet, in the inside of described ratchet, through hole is set, described through hole is arranged at the axle center of described ratchet and connects described ratchet, ratchet is connected with fork one end by axle, the other one end of described fork arranges porose, and ratchet is articulated with on fork by hole, it is characterized in that: the ratchet shape of described ratchet is set as asymmetric trapezoidal; Ratchet is and four tooth papillae pawls of the profile of tooth engagement of described ratchet, and the thickness of ratchet is set to 8mm, and the thickness of ratchet is set to 7mm.
