Abstract
The utility model discloses a torque limiter, and relates to a protecting device of overloads of a mechanical rotation component when material blocking is caused in a free sampler. The torque limiter mainly solves the problem that existing overload protection is controlled through an electric appliance, and if control through the electric appliance loses efficacy, a reamer of the sampler will be damaged or a reducer shaft will be broken. The torque limiter is characterized in that a driving ring is fixed on a middle ring through a bolt, the other circular face of the middle ring is connected with a driven ring through a steel ball, a transmission rod is connected in an axial hole of the driving ring and an axial hole of the driven ring, and the driven ring and the middle ring are in tight contact connection through the transmission rod by a gland nut for an adjusting spring on the transmission rod. The torque limiter is installed between a reducer of the sampler and the reamer, when material blocking is caused inside the sampler, output power of the reducer can be cut off, device damage and accident causing are accordingly avoided, the service life of devices is prolonged, and the operation cost and the maintaining cost are reduced.
Description
Technical field
The utility model belongs to torque limiter, specifically relate to a kind of while protecting Autosampler to avoid putty mechanical component overload damage the torque limiter of risk.
Background technique
In Autosampler; because sampling time is long; sample collector materials inside continues accumulative total until sample collector inside is blocked; if automatically controlled part overload protection lost efficacy; motor will remain in operation and continue outputting power by speed reducer; until sample collector reamer is damaged, reductor shaft is fractureed, cause irreversible accident to occur.
Summary of the invention
Order of the present utility model is for above-mentioned deficiency, and propose a kind of in the situation that overload protection lost efficacy, can guarantee that sample collector reamer and speed reducer are not damaged, alleviate the torque limiter of running cost and maintenance cost.
Technical solution of the present utility model is that torque limiter is: initiatively ring is bolted on central ring, another disc of central ring is connected with driven torus by steel ball, drive link is connected in the axial bore of active ring and driven torus, and drive link makes driven torus be connected with central ring close contact by the Regulation spring on it with gland nut.
On the junction surface of the central ring described in technical solution of the present utility model and driven torus, be provided with groove along even circumferential, steel ball is located in the groove of central ring.
Torque limiter of the present utility model is arranged between Autosampler speed reducer and spiral reamer, in the time of sample collector putty, if electrical equipment control lost efficacy, the utility model can cut off speed reducer outputting power, spiral reamer quits work, thereby has avoided the damage of sample collector spiral reamer and reductor shaft, has avoided the generation of irreversible accident, extend the working life of equipment, reduced running cost and maintenance cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, initiatively encircling 1 is fixed on central ring 2 by bolt 5, another disc of central ring 2 is connected with driven torus 6, its Placement is, on this disc of central ring 2, be provided with groove along even circumferential, in groove, be provided with steel ball 3, this face of central ring 2 is connected with driven torus 6 contacts by steel ball 3; One end of drive link 8 be connected to initiatively encircle 1 and the axial bore of central ring 2 in, drive link 8 can initiatively encircle 1 and central ring 2 in freely rotate; Drive link 8 makes driven torus 6 be connected with central ring 2 close contacts by the Regulation spring 7 use gland nuts 4 that connect thereon; When use, initiatively encircle 1 axis hole and be connected with the output shaft of Autosampler speed reducer; Drive link 8 is connected with sample collector spiral reamer, and in the time of normal work, speed reducer drives and initiatively encircles 1 rotation, and power is delivered to spiral reamer by central ring 2, steel ball 3, driven torus 6, drive link 8, spiral reamer rotation sampling.In the time of the inner putty of sample collector, spiral reamer is subject to larger resistance, and resistance feeds back to driven torus 6 by drive link 8, in the time that resistance continues to increase, driven torus 6 left side steel balls are deviate from from groove, now speed reducer outputting power is cut off, and spiral reamer is no longer worked, and makes it avoid damaging risk.
