Abstract
The utility model relates to a bidirectional self-locking brake, which can effectively solve the problem that the traditional brake is not safe and reliable. The technical scheme for solving the problems is that the bidirectional self-locking brake comprises a brake ring and an output shaft, wherein the output shaft is arranged in the center of the brake ring; the output shaft is provided with a star wheel arranged in the brake ring; the inner wall of the brake ring is in sliding contact with a fork-type wheel installed on a motor; grooves around the star wheel are provided with interference pin rollers; and the adjacent interference pin rollers in every two grooves are connected by a compression spring. The bidirectional self-locking brake has the advantages of simple structure, low cost and energy saving, is easy to install and use and is environmentally-friendly.
Description
Technical field
The utility model relates to braking machinery, particularly a kind of bidirectional self-locking break.
Background technique
Break is to have to make moving element (or movable machinery) slow down, stop or keeping the device of halted state.Be widely used in mechanical fields such as lathe, metallurgy, mine, building, building materials, communications and transportation, mass transport, elevator, petrochemical industry, engineering machinery, Aero-Space, military affairs.Break divides industrial break and automotive brake.Frictin braek and non-friction type break arranged, embrace block brake, interior shoe brake, band brake, disk type braker.
Break is the important mechanism that whole world safety in production ensures life and property.The break that uses at present is because structural problem, needs machine power, electromagnetism, hydraulic pressure, device such as pneumatic to support.Part is many, and mechanism falls behind, and action is complicated.Some the break manufacturing of the difference of Environmental Conditions is more complicated, needs machinery, electrical equipment, hydraulic pressure, the interlocking of working in coordination.Because the difference and the uncertain fault of component of Environmental Conditions lost efficacy support organization often, caused the accident.Particularly large-scale underground mine lifting means, construction machinery equipment, crane gear, facilities for transport and communication, elevator etc.How solving the safety reliability problem of break, is the technical barrier that needs to be resolved hurrily in the industry.
Summary of the invention
To above-mentioned situation, for overcoming the defective of existing technology, the purpose of the utility model just provides a kind of bidirectional self-locking break, can effectively solve safe and reliable problem.
The technological scheme that the utility model solves is; Comprise trig loop and output shaft; Output shaft is contained in the center of trig loop, and the star-wheel that places in the trig loop is housed on the output shaft, trig loop inwall and the V shape wheel sliding contact that is contained on the motor (not drawing among the figure); Groove on the star-wheel periphery is built-in with the interference roller, and adjoining interference roller is linked by pressure spring in per two grooves.
The utility model is simple in structure, and cost is low, is easy to install and use energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the structural front view of the utility model.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model.
Provide by Fig. 1; The utility model comprises trig loop and output shaft; Output shaft is contained in the center of trig loop, and the star-wheel 2 that places in the trig loop 1 is housed on the output shaft 6, and the trig loop inwall is taken turns 3 sliding contacts with the V shape that is contained on the motor; Groove on star-wheel 2 peripheries is built-in with interference roller 4, and adjoining interference roller 4 is linked by pressure spring 5 in per two grooves.
Groove on described star-wheel 2 peripheries has three that are uniformly distributed with, and each groove is built-in with two interference rollers, and V shape wheel 3 places between two interference rollers.
The working condition of the utility model is, during use trig loop is fixed on the gear housing of speed reducer, and the V shape wheel links to each other with motor, by driven by motor V shape wheel promotion interference roller, makes the pressure spring return and rotates.Drive the fixedly output shaft output on the star-wheel, the motor stall by the effect of pressure spring, back into interference position, bidirectional self-locking to left and right sides interference roller.
The utility model is safe in utilization, and the life-span is long, need not any auxiliary device, can practice thrift the great deal of raw materials and the energy, and be the innovation on the braking equipment, economic and social benefit is remarkable.
