Description
Technical field
The utility model is related to a kind of speed reducer backstopping devices with pawl, are particularly suitable for ribbon conveyer and are subtracted with pawl type
Fast machine holdback, belongs to ribbon conveyer equipment technical field.
Background technology
Ribbon conveyer is the ideal equipment for realizing remote bulk material, high speed, automation, continuative transport, extensively
It is general to be applied to the departments such as electric power, metallurgy, chemical industry, coal, mine, harbour, grain, generally by belt, roller, upper supporting roller, subiculum
The compositions such as roller impact idler.When inclined surface or heavy load are stopped phenomenon of moving backward may occur for ribbon conveyer in order to prevent, need
Check or brake apparatus are installed.Current check or brake apparatus are generally all mounted on speed reducer low speed end, by holdback housing,
The compositions such as inner sleeve, spring leaf, special-shaped block, the opposing torque formed when being inverted by inner sleeve achieve the purpose that check stops.This knot
There is the problems such as reversing positive action is not strong, service life is short, maintenance cost is high in the holdback of structure.
Utility model content
The utility model aim is to provide a kind of speed reducer backstopping device with pawl, and check effect is good, easy to maintain, uses
Long lifespan solves the problems, such as background technology.
The technical solution of the utility model is：
A kind of speed reducer backstopping device with pawl, including pawl, holdback housing, check fluted disc and reductor shaft, check
Fluted disc is fixed on reductor shaft, and the circumferencial direction of check fluted disc is equipped with ratchet, and pawl is cylinder, and one end of pawl is ball
Face structure, holdback housing be with the matched cirque structure of check fluted disc, holdback housing is fixed on check fluted disc, inverse
It is only put on outside device equipped with one and the matched through-hole of pawl, one end of pawl spherical structure, which passes through to cover outside holdback, to be led to
Hole, pawl are fixed on outside holdback and put on.
The diameter of the spherical structure of described pawl one end is more than or equal to the diameter of pawl.
The center of the check fluted disc is equipped with and the matched circular hole of reductor shaft.
Using the utility model, when ribbon conveyer belt roller rotates, drives check fluted disc to act together, work as belt
When transporter stops, check fluted disc reverses, and pawl and check fluted disc are stuck, achievees the purpose that check is shut down.
The utility model has the beneficial effects that：Compared with traditional speed reducer backstopping device, spring leaf and special-shaped block are eliminated
Equal vulnerable parts, easy to maintain, check effect is good, and service life is long.
Description of the drawings
Fig. 1 is the utility model front view；
Fig. 2 is the utility model side view；
In figure：Pawl 1, holdback housing 2, check fluted disc 3, reductor shaft 4.
Specific implementation mode
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
With reference to attached drawing 1,2, a kind of speed reducer backstopping device with pawl, including pawl 1, holdback housing 2, check fluted disc 3
With reductor shaft 4, check fluted disc 3 is fixed on reductor shaft 4, and the circumferencial direction of check fluted disc 3 is equipped with ratchet, and pawl 1 is
One end of cylinder, pawl 1 is spherical structure, and holdback housing 2 is and 3 matched cirque structure of check fluted disc, check
Device housing 2 is fixed on check fluted disc 3, set on holdback housing 2 there are one with 1 matched through-hole of pawl, 1 spherical surface knot of pawl
One end of structure passes through the through-hole on holdback housing 2, pawl 1 to be fixed on holdback housing 2.
In the present embodiment, check fluted disc 3 is the ratchet disk of GN150 models, is mounted on reductor shaft 4, and pawl 1 is circle
Cylindricality, size are：The spherical structure of radius >=15mm is processed into one end of pawl 1 by Φ 30 × 100.
Holdback housing 2 is to be fixed on check fluted disc 3 with 3 matched cirque structure of check fluted disc, holdback housing 2
On, 30.8 through-holes of Φ are beaten in the surface of holdback housing 2.
The spherical structure of pawl 1 is passed through into 30.8 through-holes of Φ, insertion depth 55mm--60mm, and pawl 1 is fixed
On holdback housing 2, pawl 1 is matched with the ratchet of check fluted disc 3.
In process, the diameter of pawl 1 is determined according to the model of check fluted disc 3 used in speed reducer, the length of pawl 1
It can determine according to actual needs.
When ribbon conveyer belt roller rotates, check fluted disc 3 is driven to act together, when ribbon conveyer stops,
Check fluted disc 3 reverses, and pawl 1 and check fluted disc 3 are stuck, achievees the purpose that check is shut down.
Compared with traditional speed reducer backstopping device, the vulnerable parts such as spring leaf and special-shaped block are removed, holdback housing is increased
And pawl, convenient for oily, abrasion is small, and service life is long.
