Technical field
The present invention relates to a kind of deceleration mechanisms of hydraulic motor.
Background technique
The deceleration of hydraulic motor is typically all to be driven by gear to realize, this maximum problem of deceleration mechanism is exactly to subtract
Speed ratio is not adjustable, and some occasions is just unable to satisfy, it is therefore necessary to be improved.
Summary of the invention
For the deficiencies in the prior art, the present invention provides a kind of deceleration mechanism of hydraulic motor, structure is simple
And different revolving speeds can be exported according to demand.
The present invention is achieved through the following technical solutions: the deceleration mechanism of hydraulic motor, including cabinet, in the cabinet
It is provided with an input shaft and an output shaft, it is characterised in that: it is the conical surface that a lateral wall is provided on the input shaft
First friction pulley, is provided with the second friction pulley that a lateral wall is cylindrical surface on the output shaft, first friction pulley and
Second friction pulley is in close contact, and the axis of the output shaft and the cross section of the conical surface are arranged in parallel, and described second rubs
It wipes slipping to be connected on the output shaft, further includes a screw rod, the both ends of the screw rod are rotatably connected on the cabinet,
A swivel nut is connected on the screw rod, the both ends of the swivel nut are provided with baffle, and the baffle is located at second friction pulley
Two sides, the swivel nut matches with screw rod.In use, by the position of rotation adjustable second friction pulley of screw rod, thus
Realize different transmission ratios, this structure is simple, and cost is relatively low, and is able to achieve continuously adjusting for revolving speed.
In above-mentioned technical proposal, it is preferred that the distance between two described baffles are greater than the thickness of second friction pulley.
In above-mentioned technical proposal, it is preferred that second friction pulley place of being connected to the output shaft is provided with flat key.
The invention has the following beneficial effects: in use, by rotation adjustable second friction pulley of screw rod position, from
And realize different transmission ratios, this structure is simple, and cost is relatively low, and is able to achieve continuously adjusting for revolving speed.
