Description

RV speed reduction multiplying torque device

Technical Field

The utility model relates to the field of machining, especially, relate to a RV speed reduction power torque device.

Background

In the field of machining, certain torque requirements are required for screwing bolts, and torque wrenches are required for torque requirements when bolts are required to be fixed. Especially, when a large torque wrench is adopted, the length is very long, the weight is heavy, and the use is inconvenient; meanwhile, potential safety hazards exist due to too large force.

The common multiple-force torque tool applied at present can amplify the torque in the using process, but the amplification factor of the torque is too small, generally 3-5 times, so that a device which can not only avoid the inconvenience of using a large-torque wrench and the occurrence of potential safety hazards, but also amplify the small torque into larger torque is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a borrow RV speed reducer principle, become big moment and do not have the multiple force torque device of potential safety hazard with the low moment amplification.

In order to achieve the above object, the utility model provides a RV speed reduction power torque device, which comprises an input end, first order increase torque device is connected to the input, first order increase torque device connects second level increase torque device, second level increase torque device connects the output.

Preferably, the first stage torque-increasing means comprises a sun gear and planet gears, the sun gear being in mesh with the planet gears.

Preferably, the second-stage torque increasing device comprises an eccentric shaft, a cycloid wheel, a supporting plate, a needle gear shell and a planet carrier, one end of the eccentric shaft is connected with the planet wheel, the other end of the eccentric shaft is connected with the supporting plate, the eccentric shaft is provided with the cycloid wheel, the needle gear shell is provided with a needle roller, the needle roller is meshed with the cycloid wheel, and the second-stage torque increasing device is connected with an output end through the planet carrier.

Preferably, the output end is a wrench head.

Preferably, the number of planet wheels and eccentric shafts is 3 each.

Preferably, the number of the cycloid gears is 2.

Preferably, the pin gear shell is fixedly connected with the limit plate.

The utility model discloses achievable beneficial effect is, accessible two-stage increase torque device enlarges into big moment with little moment, can enlarge moment to hundreds of times, is applicable to the condition of big moment demand, the situation that the incident appears when can not causing big moment spanner to use.
