Abstract

The utility model discloses a connecting device of a screw rod and a motor base. The connecting device includes a screw rod bearing which is sleeved on the screw rod and the motor base. The connecting device further comprises a bearing gland, a locknut, a first framework oil seal and a second framework oil seal. The first framework oil seal and the second framework oil seal are respectively arranged on both lateral end surfaces of the screw rod bearing. The first framework oil seal is arranged between the motor seat and the screw rod bearing, the second framework oil seal is arranged between the bearing gland and the screw rod bearing. The bearing gland is connected with the motor base. Protrusions on the bearing gland abut against an outer ring of the screw rod bearing. The locknut is arranged inside the bearing gland and is connected with the screw rod in a screw joint mode. The connecting device of the screw rod and the motor base can prevent scrap iron, dust, cutting fluid, lubricating oil and other sundries from entering the screw rod bearing so as to prolong the service life of the screw rod bearing and prolong maintenance period of the screw rod bearing.

The model utility content
Technical problem to be solved in the utility model is, can stop iron filings, dust, cutting fluid, lubricated wet goods foreign material to enter the screw mandrel bearing to improve screw mandrel bearing working life, the screw mandrel that extends screw mandrel bearing maintenance period and the connection set of motor cabinet thereby provide a kind of.
technical solution of the present utility model is, a kind of the have screw mandrel of following structure and the connection set of motor cabinet are provided, it comprises screw mandrel bearing and the motor cabinet that is socketed on screw mandrel, it also comprises bearing gland, locking nut, the first outside framework oil seal and the second outside framework oil seal, described the first outside framework oil seal and the second outside framework oil seal divide and are located at the both sides end face that screw axis holds, described the first outside framework oil seal is located between motor cabinet and screw mandrel bearing, described the second outside framework oil seal is located between bearing gland and screw mandrel bearing, described bearing gland be connected with motor cabinet and bearing gland on projection be against on the screw axis bearing outer-ring, described locking nut is located in bearing gland and is spirally connected with screw mandrel.
After adopting above structure, the connection set of screw mandrel of the present utility model and motor cabinet compared with prior art has the following advantages:
because the screw mandrel bearing two side ends face in the connection set of screw mandrel of the present utility model and motor cabinet is provided with the first outside framework oil seal and the second outside framework oil seal, the first outside framework oil seal and the second outside framework oil seal can stop iron filings preferably, dust and other impurities enters in bearing by two end faces of screw mandrel bearing, stop cutting fluid, lubricated wet goods liquid enters in the screw mandrel bearing by the gap of screw mandrel bearing both ends of the surface, thereby guarantee screw mandrel bearing cleaning inside and the cleaning that guarantees special grease and full, reduce the wearing and tearing of screw mandrel bearing, improve screw mandrel bearing working life, extend screw mandrel bearing up-time, the screw mandrel bearing does not need often maintenance and safeguards up-time after prolongation, correspondingly maintenance period is extended.
As preferably, described the first outside framework oil seal is located between motor cabinet and screw mandrel bearing and refers to, described motor cabinet is provided with annular recess towards the one side of screw mandrel bearing, described the first outside framework oil seal simultaneously is against on annular recess, one side is against on the screw mandrel bearing, the first outside framework oil seal can not only stop iron filings, dust, cutting fluid, lubricated wet goods foreign material to enter the screw mandrel bearing well, and the annular recess that the first outside framework oil seal is installed on motor cabinet is easy to process, and the first outside framework oil seal is installed and also is easier to.
As preferably, described the second outside framework oil seal is located between bearing gland and screw mandrel bearing and refers to, described bearing gland inboard is provided with annular slot, the second outside framework oil seal simultaneously is against on the screw mandrel bearing, another side is against the annular slot place of bearing gland, compress the second outside framework oil seal and screw mandrel bearing by bearing gland, prevent that iron filings, dust, cutting fluid, lubricated wet goods foreign material from entering the screw mandrel bearing, the second outside framework oil seal is installed more convenient.
As preferably, described the first outside framework oil seal and the second outside framework oil seal are the Double-lip framework oil sealing, and it is better that the Double-lip framework oil sealing is put the dust anti-leak result.
As improvement, it also comprises trembleuse cup, and described trembleuse cup is fixedly connected with motor cabinet, and trembleuse cup plays the effect of buffering.
