SU424398A1 - Face Ratchet Wrench - Google Patents

Description

I

The invention relates to an assembly tool and can be used in any industry where it is necessary to fasten fasteners.

Known mechanical ratchet wrench, containing a housing with a handle, conical

a gear and two working heads, kinematically connected with a bevel gear by means of ratchet mechanisms, including the left and right ratchet wheels

rotations

j The known key is actuated by rotating the handle in a circular fashion, which limits its use in places that do not allow the handle to rotate in a circular fashion, i.e. in difficult places.

In addition, in a known key, both working heads rotate simultaneously on the / one side, i.e. either screwing or unscrewing the fastener is performed. 1 In order to ensure operation in hard-to-reach places and to ensure multidirectional rotation of the working heads of the proposed face ratchet wrench, the conic transmission was implemented in the form of differential gears with two mutually perpendicular output shafts carrying working heads, hp wheels of bearing; The fuse: shy on the axes of the satellites of the differential, and the handle is complete in the form of a swing; open loop frames with 10 tanks on the free ends, through which it interacts genetically with the corresponding ratchet wheel.

The drawing shows the kinematic

1D s.hema proposed key.

i It contains a conic differential with gears 1-4 and two output shafts 5 and 6, on which they are mounted

20 interchangeable working heads 7 and 8. The handle, 9 is installed in the slots of the body (on the black; not shown) and is connected to the satellites of the differential through the ratcheting mechanisms | 10 and 11, one of which is left and the other right-hand rotation. On the free ends of the handle t2si, in the fe-shaped form of the swinging frame of an unclosed contour, ratchet dogs MexairaaMOB are fastened, for fixing the fastener the working head g

Cu 7 is installed and secured to the output shaft 6. The working head is put on the nut, then turning the handle 9 towards you and away from you, i.e. Together with it, the oscillatory motion is made to tighten the nut. When the handle is turned towards itself, the nut is transmitted through the ratchet mechanism 10, 1 and the gear 1-4, the output shaft 6 with the working head 7. The ratchet mechanism 11 rotates. idle and takes effect when you turn the knob away from yourself. Working hopeful 8 in this case can be removed. The fastening is unscrewing in the same way as screwing through the working head 8. The working heads can be replaced with a screwdriver. In this case-. You can tighten the screws and screws.
