Abstract
The utility model relates to a ratchet wheel backstop, including ratchet and pawl, set up a draw -in groove on the ratchet wheel hub, install in the draw -in groove rather than mating snap ring, the snap ring be two and half the ring structure with the bolt concatenation, installs compression spring on the bolt, bore on the snap ring be equipped with one with the fixed mounting hole of connecting rod, the connecting rod other end is fixed with the pawl, pawl one side is equipped with the stop device and the spacing bolt of regulation its and ratchet distance. The beneficial effects of the utility model are that: the pawl was thrown off when bucket elevator ratchet wheel backstop can guarantee to run well, meshed during reverse operation, moved more reliably, and the noiseless does not have wearing and tearing, reformed transform with low costsly, and life is extra long, and application effect is very good.
Description
Technical field
The utility model relates to a kind of ratchet holdback.
Background technology
Common bucket elevator ratchet holdback forms primarily of ratchet, ratchet and bearing pin.In real work, because ratchet contacts with ratchet all the time, ratchet gear teeth height rises and falls, and ratchet often turns over gear teeth and all can clash into ratchet, and noise is comparatively large, and easy to wear, service life is short.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of ratchet holdback.
The utility model solves the technical scheme that its technical matters adopts: a kind of ratchet holdback, comprise ratchet and pawl, ratchet wheel hub is offered a draw-in groove, snap ring with its pairing is installed in draw-in groove, snap ring is two semicircular ring structures with bolt splicing, and bolt is provided with Compress Spring, snap ring is drilled with a mounting hole fixed with connecting rod, the connecting rod other end and ratchet are fixed, and ratchet side is provided with the inhibiting device and caging bolt that regulate itself and ratchet distance.
Further, respectively there is 1mm in snap ring both sides and draw-in groove wall gap.
Further, the pawl point of ratchet is limited in lOmm farthest with the distance of the tooth top circle of ratchet.
The beneficial effects of the utility model are: when bucket elevator ratchet holdback can ensure normal operation, ratchet is thrown off, and engages during reversed operation, and run more reliable, noiseless, without wearing and tearing, improvement cost is low, and service life lengthens, and effect is very good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. ratchet, 2. ratchet, 3. snap ring, 4. Compress Spring, 5. connecting rod, 6. inhibiting device, 7. caging bolt.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of ratchet holdback as shown in Figure 1, comprise ratchet 1 and ratchet 2, a draw-in groove offered by ratchet 1 wheel hub, snap ring 3 with its pairing is installed in draw-in groove, snap ring 3 is two semicircular ring structures with bolt splicing, bolt is provided with Compress Spring 4, snap ring 3 is drilled with a mounting hole fixed with connecting rod 5, connecting rod 5 other end and ratchet 2 are fixed, and ratchet 2 side is provided with the inhibiting device 6 and caging bolt 7 that regulate itself and ratchet 1 distance.
Respectively there is 1mm in snap ring 3 both sides and draw-in groove wall gap.The pawl point of ratchet 2 is limited in lOmm farthest with the distance of the tooth top circle of ratchet 1.
By forward rotating bucket lifting head axle, observe snap ring whether with ratchet rotating Vortex, drivening rod pushes ratchet open simultaneously.If snap ring can not with ratchet synchronous rotary, then regulate the pressure of Compress Spring by bolt, increase the friction force of snap ring and ratchet, until can with ratchet synchronous rotary.Then adjust caging bolt, make the pawl of ratchet point be limited in about lOmm farthest with the distance of the tooth top circle of ratchet.When so both ensureing forward to rotate, ratchet is thrown off and is touched less than ratchet, and when making again retrograde rotation, ratchet engages with ratchet in a short period of time.
Normal when forward operating, snap ring under the effect of friction force with ratchet rotating Vortex, drivening rod pushes ratchet open simultaneously.When ratchet turns to caging bolt position, because the application force of caging bolt to ratchet is greater than the friction force that snap ring and ratchet ask, now snap ring skids on ratchet, and not with ratchet synchronous rotary, ratchet, connecting rod and snap ring can only be static.Ratchet is in disengaged condition always, can not produce and clash into, noiseless with ratchet.In like manner, during retrograde rotation, snap ring drivening rod, pulls to ratchet by ratchet, and final ratchet engages with ratchet, plays the effect of check.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
