Description

The waterproof device for revolving and driving

Technical field

The utility model relates to a kind of device for revolving and driving, especially a kind of waterproof device for revolving and driving.

Background technique

Device for revolving and driving is a kind of device that is widely used in industries such as engineering machinery, building machinery, photovoltaic.Usually, device for revolving and driving need move under physical environment and severe environmental conditions, especially in areas such as tropical rain forests; Under the heavy rain weather conditions of being everlasting, move; The inner water inlet easily of device has a strong impact on the inner tooth portion back lash of device etc., causes device to reduce greatly working life.Therefore, increasingly high requirement has been proposed its water-tight performance.Usually the method that adopts is to install rain cover additional to device for revolving and driving, perhaps adopt conventional water-tight structure, but its sealed waterproof effect is all undesirable, and the device for revolving and driving using scope is restricted.

The model utility content

The inventor is through discovering, the device for revolving and driving water inlet mainly contains three approach: the one, and the gap between pedestal and the top board, general sealing can only guarantee not invading of sand and dust, can not stop rainwater such as heavy rain to penetrate into through the gap between pedestal and the top board; The 2nd, the surface of contact and the mounting hole of pedestal and pivoting support inner ring, water gets into through the mounting hole of ring gap and inner ring in pedestal and the pivoting support; The 3rd, the immersion that all mounting holes, water can be slowly.

The purpose of the utility model is in order to solve the technical problem of the water-tight poor performance that device for revolving and driving exists, and provide a kind of simple in structure, cost is low, make and be easy to high performance waterproof device for revolving and driving.

For realizing the utility model purpose; This waterproof device for revolving and driving comprises pedestal (5), pivoting support (15), worm screw (8), and said pedestal (5) partly is made up of axle housing and seat ring (41) two; The shaft axis of the shaft axis of axle housing and seat ring (41) is orthogonal in the spatial position; Said worm screw (8) is installed in the axle housing of pedestal (5), said pivoting support (15) comprise inner ring (31), external toothing (32) and be embedded at inner ring (31) and external toothing (32) between ball (33), external toothing (32) is provided with some installation screws; Inner ring (31) is fixed on the top of the seat ring (41) of pedestal (5); External toothing (32) and worm screw (8) engagement also are provided with top board (18), and said top board (18) is provided with external toothing (32) the corresponding hole of screw is installed; Top board (18) is installed on the top of external toothing (32) and inner ring (31); Between external toothing (32) and the seat ring (41) lip-type packing (16) is installed also, said inner ring (31) is provided with some downward opening blind holes, and pedestal (5) is provided with inner ring (31) and goes up the corresponding mounting hole of blind hole; Be provided with Ο shape seal ring between the upper surface of top board (18) and inner ring (31), said top board (18) all is connected through bolt, waterproof washer with seat ring (41) with external toothing (32), inner ring (31).

The technological scheme that is more preferably is: the below of top board (18) is provided with annular protrusion (29), and annular protrusion (29) is inboard to have Ο shape seal ring (19,20) with arranged outside.

The technological scheme that is more preferably is: seat ring (41) is provided with ring-shaped step (42), and an end face of said lip-type packing (16) is installed on the ring-shaped step (42).

The technological scheme that is more preferably is: the below of top board (18) is provided with annular protrusion (29); Annular protrusion (29) is inboard to have Ο shape seal ring (19,20) with arranged outside; Said seat ring (41) is provided with ring-shaped step (42), and an end face of said lip-type packing (16) is installed on the ring-shaped step (42).

In the utility model; Be motive sealing between top board and seat ring, the inner ring, utilize the interference of lip-type packing lip and self fastening function to make Sealing produce resiliently deformable, block the gap; Because lip has bigger spring-back force, thereby realize the water-tight between top board and the seat ring; Adopt the extrusion pressing type sealing between the inner ring of top board and pivoting support, make the Ο RunddichtringO produce resiliently deformable, block the gap, realize water-tight by extruding force is installed; The porose static seal structure that is utilizes pad to be sealed under the impacting force effect, and packing ring self produces elasticity and plastic deformation, and gap between the fill plug seal face reaches the purpose of sealing.Simultaneously, all should smear an amount of grease when lip-type packing, Ο shape seal ring are installed, when construction bolt and waterproof are synthesized packing ring, can smear an amount of sealer, thereby realize high-grade sealed waterproof effect.

The utility model solved in the device for revolving and driving three very easily key positions water inlet problems of water inlet, solved the worry that device that the user causes because of the device water inlet can not normally use, and the classification of waterproof of the utility model can reach more than the IPX6.

The utility model design science, rationally original, practical effect is excellent, efficient is high, installs simply, easy to maintenance, reliable and stable, has good development prospect, and the utility model is applicable to that industries such as engineering machinery, building machinery, photovoltaic use.

Need to prove that under the prerequisite of principle that does not change the utility model and design, can also make some changes or distortion to the utility model, this belongs to the protection domain of the utility model equally.
