Abstract
A power tool comprises a housing having at least two housing parts and at least one recess, a portion of the recess provided by each housing part, and a bearing located in the recess. The power tool includes a seal comprising an elongate seal member located between the housing parts to seal at least a portion of the housing. The seal includes at least one polymeric extension part extending from the elongate seal member and in contact with an external part of the bearing without extending around the bearing. The polymeric extension part of the seal prevents the external part of the bearing from rotating with respect to the housing during use of the power tool.
Claims16
A Power tool, comprising:
- a housing having at least two housing parts, each housing part having an inner portion defining a recess therein;
- a bearing located in the housing, the bearing having an outer race, wherein the respective recesses of the two housing parts mate around the outer race of the bearing and come in direct contact with the outer race of the bearing to support the bearing inside the housing;
- and
- a seal comprising an elongate seal member located between the housing parts to seal at least a portion of the housing;
- wherein the seal includes at least one polymeric extension part extending from the elongate seal member between the two housing parts and in direct contact with the outer race of the bearing without extending around the bearing, so as to prevent the outer race of the bearing from rotating with respect to the housing during use of the power tool.
A power tool, comprising:
- a main outer housing;
- an inner housing having at least two housing parts disposed within the main outer housing, each housing part having an inner portion defining a recess therein;
- an opening formed between the at least two housing parts of the inner housing the opening providing access to an inner portion of the inner housing to facilitate machining of the respective recesses within the two housing parts, wherein a portion of the opening is provided by each housing part;
- a bearing located in the housing, the bearing having an outer race, wherein the respective recesses of the two housing parts mate around the outer race of the bearing and come in direct contact with the outer race of the bearing to support the bearing inside the housing
- a seal comprising an elongate seal member located between the housing parts to substantially seal at least a portion of the inner housing;
- and
- a substantially planar-shaped plug member located in the opening to close the opening of the inner housing to an inner portion of the main outside housing, the plug member having a first face facing the inner portion of the inner housing and a second face facing the inner portion of the main outside housing;
- wherein the elongate seal member extends between the at least two housing parts around the plug member to seal between the plug member and the inner housing.
