Abstract
The utility model discloses a claw type shaft coupler which comprises two bases, wherein a rotating shaft is arranged between the two bases, a handle is fixedly arranged at the end part of the rotating shaft, a U-shaped shifting fork disc is fixedly arranged in the middle part of the rotating shaft, and main control pawls are clamped between jack catches of the U-shaped shifting fork disc; and a main transmission shaft is arranged above the bases, and fixing pawls which are matched with the main control pawls are fixedly arranged on the main transmission shaft. The claw type shaft coupler is simple and convenient for operation, and can avoid the restraint of main transmission by reasonably configuring assistant transmission according to the design requirements, thus reducing abrasion and prolonging service life.
Description
Technical field:
The utility model relates generally to the transmission device of noria, especially when helper drive is arranged, is used for the paul pawl coupling that is connected between main transmission and the helper drive.
Background technique:
Noria is widely used in the material-transporting system of industries such as building materials, chemical industry, grain because motion speed is fast, so, when test run and regular maintenance are checked, need a kind ofly help manual observation than low speed, this just needs to increase helper drive.Helper drive is a kind of low speed transmission device that is superimposed upon on the main gear reducer.Traditional helper drive is connected one with main transmission by coupling, and the helper drive load-bearing is in main transmission.When main transmission was worked, helper drive was followed passive transport, and coupling damages through regular meeting, and the helper drive specification is retrained by main transmission also.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of novel paul pawl coupling is provided, it is installed between speed reducer and the helper drive, when main transmission is worked, with helper drive and its disengaging, accomplish that helper drive does not turn round, can also be with the helper drive independent stationary, apolegamy is extensively changed conveniently.
The utility model is achieved through the following technical solutions:
Paul pawl coupling includes two bases, between two bases rotating shaft is installed, and described roller end is installed with handle, and described rotating shaft middle part is installed with U-shaped fork dish, and clamping has the master control ratchet between the claw of described U-shaped shift fork dish; There is main drive shaft the base top, and fixed pawl fixing and master control ratchet coupling is installed on the described main drive shaft.
Described paul pawl coupling is characterized in that: described base one side is provided with the base corresponding with handle position.
Described paul pawl coupling is characterized in that: on the described master control ratchet annular protrusion is arranged, the claw of described U-shaped fork dish is clamped in the annular protrusion both sides.
Stroke for the restriction handle is provided with base, and base can limit the handle stroke and prevent to cause fork dish and prominent ring to break away from because of rotation amplitude is excessive.
The utility model by the master control ratchet with the position change between the fixed pawl, make main gear reducer and helper drive in conjunction with separate.
The utility model makes the rotating shaft left-right rotation by pulling handle, and then makes before and after the U-shaped fork dish and rotate, realize the master control ratchet with the combination of fixed pawl with separate.
When main drive shaft was worked, helper drive and the utility model broke away from, and had reduced helper drive service time, had avoided fatigue damage.When the helper drive independent stationary, alleviate the main transmission load-bearing, strengthen main transmission working life indirectly.
The utility model has the advantages that:
The utility model is simple, and is easy to operate; According to the design needs, the reasonable disposition helper drive makes it retrained by main transmission, and then reduces wear, and has increased working life.

Embodiment:
Paul pawl coupling includes between 2, two bases 2 of two bases rotating shaft 5 is installed, and described rotating shaft 5 ends are installed with handle 1, and described rotating shaft 5 middle parts are installed with U-shaped fork dish 6, and clamping has master control ratchet 3 between the claw of described U-shaped shift fork dish 6; On the described master control ratchet 3 annular protrusion 8 is arranged, the claw of described U-shaped fork dish 6 is clamped in annular protrusion 8 both sides.There is main drive shaft base 2 tops, are installed with on the described main drive shaft and the fixed pawl 4 of deciding master control ratchet 3 couplings.Described base 2 one sides are provided with the base 7 corresponding with handle 1 position.
