Abstract
The utility model provides a rapid-reducing clutch. The main technical structure is that: an outer shell is covered out of a single-row tapered roller bearing via a bolt; the inner side of the single-row tapered roller bearing is a gland screw nut; a gland screw rod and a screw nut are covered on the gland screw nut; a washer is padded between the gland screw nut and the single-row tapered roller bearing. Compared with the prior art, the advantages of the rapid-reducing clutch are that: the rapid-reducing clutch is arranged on an electric hoist, which causes the electric hoist to have the function of rapidly descending to impact and break the object.
Description
Technical field
The utility model relates to engineering machinery, and is particularly relevant with electric wire hoist equipment.
Background technique
At present, existing electric wire hoist only has the effect that weight is slowly promoted and slowly descends, its function singleness.
Summary of the invention
According to above-mentioned existing problem, the spy designs this product, and its objective is provides a kind of proprietary parts prompt drop clutch that can realize that electric wire hoist descends rapidly.
Major technique structure of the present utility model is as follows;
Shell covers in outside the single-row tapered roller bearing by screw, and the single-row tapered roller bearing inboard is a gland nut, and gland screw rod and nut sleeve are enclosed within on the gland nut, and the packing ring pad is between gland nut and single-row tapered roller bearing.
The utility model is compared its advantage with prior art and is that this prompt drop clutch is installed on the electric wire hoist, makes it have the function that quick decline is impacted, smashed object.
Description of drawings
Concrete technical pattern of the present utility model is provided by the following drawings.
Fig. 1 is the utility model general structure schematic representation;
Fig. 2 is the A-A cut-away view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in Figure 1, 2, shell 1 covers in single-row tapered roller bearing 5 outsides by screw 7, be used to limit single-row tapered roller bearing 5 longitudinal movements, single-row tapered roller bearing 5 inboards are gland nuts 2, gland screw rod 6 and nut sleeve 3 are enclosed within on the gland nut 2, be used to clamp single-row tapered roller bearing 5 overcoats, packing ring 4 pads are between gland nut 2 and single-row tapered roller bearing 5.When moment is passed to the electric gourd drum work that hoists, is risen be raised to constrain height and stop after, press the decline push button, make nut sleeve 3 despinings, thereby the prompt drop clutch unclamps single-row tapered roller bearing 5 overcoats, make the weight broken object that descends rapidly.The present invention is applied on other machinery after can passing through a screw axis and gland nut 2 cooperate.
Claims (1)
1, a kind of prompt drop clutch, it mainly is made up of tapered roller bearing, screw rod, nuts and washers, it is characterized in that: shell (1) passes through screw (7) fixed cover in single-row tapered roller bearing (5) outside, single-row tapered roller bearing (5) inboard is gland nut (2), gland screw rod (6) and nut sleeve (3) are enclosed within on the gland nut (2), and packing ring (4) fills up between gland nut (2) and single-row tapered roller bearing (5).
