Abstract
The invention relates to a big locking nut assembling and disassembling tool which comprises a wrench and a sleeve. The key points are that four positioning keys are uniformly distributed on the end face of the opening of the sleeve; a pulling pin hole and a torque measuring square hole are formed in the wrench end face of the sleeve; the wrench is provided with a pulling cylindrical pin and a lengthened pin column both matching with the pulling pin hole; the wrench and the sleeve are connected through the pulling cylindrical pin and the pulling pin hole. The big locking nut assembling and disassembling tool is simple in structure, easy to produce, and convenient to assemble and disassemble as the wrench and the sleeve are connected by adopting the cylindrical pin; as the wrench is provided with the lengthened pin column, convenience is brought to connection of a lengthened rod, and force is saved and security is ensured when a big locking nut is wrenched; as the sleeve is provided with the torque measuring square hole, screwing torque is measured conveniently, a big nut is ensured to be mounted in place, a rolling body is stressed uniformly, service life of a bearing is prolonged, and integral performance of a traveling speed reducer is increased; the tool is suitable for assembling and disassembling big nuts of traveling speed reducers of the series of 6 tons, 7 tons, 8 tons, 9 tons and the like, and is good in universality and practicability.
Description
Technical field
The present invention relates to a kind of installing/dismounting frock, be specifically related to a kind of locking big nut installing/dismounting frock for driving speed reducer.
Background technology
The locking big nut of the driving speed reducer of excavator effectively raises the pretightning force of large bearing axis, extends the service life of bearing, also improves the overall performance of driving speed reducer simultaneously.And install, when dismantling big nut, the moment that big nut needs is large, adopt conventional spanner, the time-consuming effort of installing/dismounting, the installing/dismounting time is long, also easily damages spanner and big nut, next is because big nut size is large, conventional torque spanner can not be used to measure the screw-down torque of big nut, preloading of the bearing that also just cannot effectively control, safety and reliability can not get ensureing.
Summary of the invention
The object of the invention is the deficiency that will overcome above-mentioned technology, a kind of low price is provided, easy to operate, for the locking big nut installing/dismounting frock of driving speed reducer.
Locking big nut installing/dismounting frock of the present invention, comprises spanner and sleeve, it is characterized in that: the running-on end face of described sleeve is evenly equipped with four positioning keys, and the spanner end face of sleeve is provided with pulls pin-and-hole; Described spanner be provided with pull that pin-and-hole matches pull straight pin, pull straight pin and be fixed tightly on spanner by nut; Described spanner is connected by pulling straight pin and pulling pin-and-hole with sleeve.
In order to better realize above-mentioned purpose:
The center of the spanner end face of described sleeve is provided with the torgue measurement square hole measuring big nut moment.
The two ends of described spanner are also provided with the lengthening pin connecting extension bar, lengthen pin and are fixed tightly on spanner by nut.
Locking big nut installing/dismounting frock of the present invention, structure is simple, easy to manufacture, and spanner and sleeve adopt straight pin to be connected, easy to loading and unloading, spanner is provided with lengthening pin, facilitates the connection of extension bar, not only laborsaving but also safety during twisting big nut, sleeve is provided with torgue measurement square hole, be convenient for measuring screw-down torque, ensure that big nut is in place, rolling element uniform stressed, extend bearing life, thus improve the overall performance of driving speed reducer; This frock is applicable to that the big nut of the serial driving speed reducers such as 6 tons, 7 tons, 8 tons, 9 tons is installed, dismounting, versatility and practicality good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, spanner, 2, pull straight pin, 3, sleeve, 4, positioning key, 5, torgue measurement square hole, 6, lengthen pin, 7, running-on end face, 8, spanner end face.
Detailed description of the invention
Locking big nut installing/dismounting frock of the present invention, comprises spanner 1 and sleeve 3.The running-on end face 7 of sleeve 3 is evenly equipped with four positioning keys 4, the spanner end face 8 of sleeve 3 is provided with pulls pin-and-hole and torgue measurement square hole 5.Spanner 1 be provided with pull that pin-and-hole matches pull straight pin 2 and be connected the lengthening pin 6 of extension bar, pull straight pin 2 and lengthening pin 6 is fixed tightly on spanner 1 by nut.Spanner 1 is connected by pulling straight pin 2 and pulling pin-and-hole with sleeve 3.
When locking big nut on driving speed reducer macro-axis is installed, sleeve 3 is enclosed within big nut, four positioning keys 4 of sleeve 3 snap in four grooves of big nut, two of spanner 1 pull and correspondingly on spanner end face 8 that straight pin 2 inserts sleeve 3 pull in pin-and-hole, rotary spanner 1 can be tightened or loosening big nut, take off spanner 1, the square toes of torque spanner are inserted in the torgue measurement square hole 5 on the spanner end face 8 of sleeve 3, pull the screw-down torque that torque spanner can measure big nut, ensure that large bearing preloads.When screw-down torque is larger, also connect extension bar by the lengthening pin 6 on spanner 1, so both laborsaving and security good.
